    In 2000 I reported at this symposium about multi-institutional graduate field trips to IAVCEI events, such as the Bali meeting and its importance in building international collegiality and awareness among the volcanology doctoral students. NSF was an enthusiastic supporter of these field sessions and this support has continued through the highly successful Pucon and Reykjavik sessions. International volcanology graduate program development began with several exchange programs. EHaz was a highly successful program (McGill, Simon Fraser, Michigan Tech, Buffalo, UNAM and Universidad de Colima) funded by the Department of Education (FIPSE) that moved students across North America where dozens of graduate students spent semesters of their study abroad and shared annual field trips and online student led graduate seminar classes. Michigan Tech’s volcanology graduate program started a Masters International program that combined Peace Corps service with hazards mitigation graduate study and students were placed by Peace Corps in countries with prominent natural hazards. The new program funded 2 year residences in foreign environments, principally in Pacific Latin America. NSF strongly supported this program from its inception, and eventually it gained NSF PIRE support. Dozens of students have initiated the 3 year program (15 completed) to date. A similar PIRE developed at UAF with a link to volcanology in the Russian Far East. One gain is the development of many socially-conscious research selections. Beginning this year transatlantic dual degree masters programs in volcanology are being offered by a consortium of US and European volcanology programs (Michigan Tech, Buffalo, Clermont Ferrand and University of Milan Bicocca), again aided by FIPSE funding. Students have dual advisors on both sides of the Atlantic and spend about half of their two year programs in Europe and half in US. Faculty also travel in the program and the four campuses are increasingly linked by

    Full Text Available Modelling has been used in the study of volcanic systems for more than 100 years, building upon the approach first applied by Sir James Hall in 1815. Informed by observations of volcanological phenomena in nature, including eye-witness accounts of eruptions, geophysical or geodetic monitoring of active volcanoes, and geological analysis of ancient deposits, laboratory and numerical models have been used to describe and quantify volcanic and magmatic processes that span orders of magnitudes of time and space. We review the use of laboratory and numerical modelling in volcanological research, focussing on sub-surface and eruptive processes including the accretion and evolution of magma chambers, the propagation of sheet intrusions, the development of volcanic flows (lava flows, pyroclastic density currents, and lahars, volcanic plume formation, and ash dispersal. When first introduced into volcanology, laboratory experiments and numerical simulations marked a transition in approach from broadly qualitative to increasingly quantitative research. These methods are now widely used in volcanology to describe the physical and chemical behaviours that govern volcanic and magmatic systems. Creating simplified models of highly dynamical systems enables volcanologists to simulate and potentially predict the nature and impact of future eruptions. These tools have provided significant insights into many aspects of the volcanic plumbing system and eruptive processes. The largest scientific advances in volcanology have come from a multidisciplinary approach, applying developments in diverse fields such as engineering and computer science to study magmatic and volcanic phenomena. A global effort in the integration of laboratory and numerical volcano modelling is now required to tackle key problems in volcanology and points towards the importance of benchmarking exercises and the need for protocols to be developed so that models are routinely tested against real

  4. Undergraduate and graduate education in Volcanology at University of Bristol, UK

    2002-05-01

    Volcanology education at Bristol is unique for several reasons. The Bristol group operates within a University Research Centre in Environmental and Geophysical Flows (CEGF), involving over 30 staff-to-PhD-level researchers, centered around close collaboration between 4 depts including Earth Sciences and Applied Maths. The uniquely-multidisciplinary setting supports training in volcanology with strong emphasis on combining field-based physical volcanology, theoretical modelling and simple analogue lab experiments. PhD students gain expertise in at least 2 of these 3 aspects during the PhD. Our dept itself is one of the most multidisciplinary in Earth Sciences and is ranked among the 3 leading ES Depts for its research quality. At dept level, there is a strong focus on understanding physical and chemical processes of magmatic/volcanic systems. Teaching/training of students is thus supported by excellent research, and aims at providing profound insights and practical experience into research. At undergraduate level, key experiences of students include 1.) a week-long field class to textbook-quality field sections on one of the most studied active volcanoes (Santorini, Greece), 2.) an independent project where the aim is to learn about all aspects of research as part of a well-focused study including gaining the experience of producing one potentially-publishable paper, 3.) a hands-on research project centered on using the latest analytical methods to solve a problem - this is most successful for 2 reasons: a.) Bristol hosts the EU Geochemical Facility and coordinates an EU Marie Curie Training Centre and b.) the students operate the instruments themselves (ie. they are not run for them); 4.) fourth-year students are especially challenged on the quantitative front (computer programming, statistical data analyses and hypothesis testing -we have excellent computer labs support for teaching), advanced field work and several independent projects. Students are helped into

    2010-12-01

    Michigan Tech, Buffalo, Universite Blaise Pascal and University of Milan Bicocca have formed an educational consortium to offer dual MS degrees in volcanology and geotechniques. Students in the program spend half of their MS in Europe and half in the US and have graduate advisory committees that bridge the Atlantic. The new program combines the expertise of four campuses and give students a broader choice of study options than any one campus can offer, while building an international professional experience. The initiative is funded jointly by the US Department of Education and the Education, Audiovisual and Culture Executive Agency (EACEA) of the European Community. Volcanology and geotechniques are global concerns: the volcanological community is fully globalized, while international consortia now deal with major geotechnical problems. Importantly, both fields require clear appreciation of specific local cultural, social and economical conditions. The new generation of researchers and professionals require international vision, but also the ability to understand local conditions. This masters specifically answers this need. This program will give students a language and cultural training in American English, French and Italian, as well as a wide course choice to meet each individual’s professional requirements. Students benefit from both research and professional approaches, acquiring a sound multidisciplinary profile for an excellent start to their careers. The trained INVOGE masters students will: meet a clear need for professionals/researchers with broad volcanology/geotechniques skills, and provide a workforce with international vision, but capable of addressing local projects. The project is innovative, combining international experience, strong multidisciplinary grounding and a broad subject range: students can choose among many possible advanced coursework and research combinations, and can have a broad choice of graduate advisors, field sites and

  6. Experimental Volcanology: 2010 and 2020

    2010-12-01

    The advent of an experimental approach to volcanology has its roots in decades-old laboratory based approaches to characterising the properties of magmas and analog materials, together with the attempts at simulating volcanic processes in the lab. A little over ten years ago many new thrusts of experimental advance led to a new dawn for experimental science applied to volcanic eruptions. Along with that, new expectations, new goals and new strategies emerged about ten years ago. Ten years later, in 2010, many fruits have been born of this labour, and new frontiers are being unfolded as we meet here. Here are some of the youngest captivating themes being explored in experimental programs today: 1) interfacing volcanic monitoring systems to experimentally generated eruptions. 2) elucidating the physicochemical behavior of experimentally generated volcanic ash as an agent in the earth system. 3) blending experimental rock deformation and magmatology studies to understand the strength and stability of volcanic materials and volcanic structures 4) exploiting the kinematics of experimentally-generated versus natural volcanic products to understand flow style and strain history. The past ten years of experimental developments in volcanology have prepared us for great advances in the future, most of which were not perceived as likely avenues of investigation as little as ten years ago! The situation is likely to repeat itself in 2020.

    After five years experience in bringing American students to meet and learn with Russian students in Kamchatka and bringing Russian students to meet and learn with American students in Alaska, it is possible to make some generalizations about the problems and benefits this growing program. Some 200 students, including many from other countries besides the United States and Russian Federation, have now had this experience. The context of their collaboration is the International Volcanological Field School, sponsored by the University of Alaska Fairbanks, Kamchatka State University, and the Institute of Volcanology and Seismology, and also a comparison of Mount St Helens, Bezymianny, and Shiveluch volcanoes under the National Science Foundation's Partnerships in International Research in Education, with important support from the Russian Academy of Sciences, Far East Division. Elements of these two projects are adaptation to unfamiliar, harsh, and remote environments; intensive courses in Russian language, history, geography, and culture; and sharing of research and education experiences among students. The challenges faced by the program are: · Slow and complex visa processes. · Demise of a direct airline connection, necessitating round-the-world travel to go 3000 km. · Adequately communicating to students beforehand the need for physical fitness, mental fortitude in uncomfortable conditions, and patience when bad weather limits mobility. Benefits of the projects have been: · Experiences that students report to be career- and life-changing. · Much more positive perceptions of Russia and Russian people by American students and of America and Americans by Russian students. · Introduction to the "expedition style" volcanology necessary in challenging environments. · Development of long-lasting collaborations and friendships in the context of international science. Students often comment that hearing about what their peers have done or are doing in research at

    In many scientific fields, decades are the time intervals of choice for retrospective and prospective reflections and speculations. AGU Session V02 seeks to apply this perspective to the assessment of where volcanology has been since 2000 and where it is headed in the next ten years. Most sciences progress through incremental observational, experimental and theoretical steps, accelerated by the identification of new socially-relevant applications, technological breakthroughs or conceptual insights, and jolted by largely unanticipated events. Volcanology is unusual in the dominant role that unpredictable eruptive observations play in controlling the evolution of the discipline. As a result, the most important constraints on how the field will change are virtually unknowable. At a session at the Fall AGU meeting in 2000 on "Volcanology 2010" a dozen talks sought to forecast how volcano science and policy would change in the next ten years, focusing on such topics as seismology, petrology, remote sensing, deformation, volcano-tectonic interactions, communications, graduate education, international cooperation, numerical modeling, database querying, and networking of observatories. While progress occurred in many of these areas, what was perhaps the most important influence on volcanology was not mentioned: for the first 9.5 years of the decade, there were no eruptions disastrous or novel enough to garner global public or political attention, with associated prioritization by funding agencies. The notable exception was the eruption of Eyjafjallajökull in mid-2010, which captured the western world’s attention due to the magnitude of the disruption, the frustrating inability of scientists to provide guidance, and the fortunate lack of casualties. We can expect continuing technical advances in all aspects of geoscience to improve the understanding of volcanic processes in the coming decade. However, another natural disaster in 2010 might hold more relevance for how

    Through funding from the European FP7 programme, the International Civil Aviation Authority (ICAO), as well as the local Icelandic government and RANNÍS research fund, the establishment of the Icelandic volcano observatory (VO) as a cross-disciplinary, international volcanological data node and data service is starting to materialize. At the core of this entity is the close collaboration between the Icelandic Meteorological Office (IMO), a natural hazard monitoring and research institution, and researchers at the Earth Science Institute of the University of Iceland, ensuring long-term sustainable access to research quality data and products. Existing Icelandic Earth science monitoring and research infrastructures are being prepared for integration with the European EPOS infrastructure. Because the VO is located at a Met Office, this infrastructure also includes meteorological infrastructures relevant to volcanology. Furthermore, the FP7 supersite project, FUTUREVOLC cuts across disciplines to bring together European researchers from Earth science, atmospheric science, remote sensing and space science focussed on combined processing of the different data sources and results to generate a multiparametric volcano monitoring and early warning system. Integration with atmospheric and space science is to meet the need for better estimates of the volcanic eruption source term and dispersion, which depend not only on the magma flow rate and composition, but also on atmosphere-plume interaction and dispersion. This should lead to better estimates of distribution of ash in the atmosphere. FUTUREVOLC will significantly expand the existing Icelandic EPOS infrastructure to an even more multidisciplinary volcanological infrastructure. A central and sustainable part of the project is the establishment of a research-quality data centre at the VO. This data centre will be able to serve as a volcanological data node within EPOS, making multidisciplinary data accessible to

    Full Text Available An emerging challenge in modern volcanology is the apparent contradiction between the perception that every volcano is unique, and classification systems based on commonalities among volcano morphology and eruptive style. On the one hand, detailed studies of individual volcanoes show that a single volcano often exhibits similar patterns of behaviour over multiple eruptive episodes; this observation has led to the idea that each volcano has its own distinctive pattern of behaviour (or personality. In contrast, volcano classification schemes define eruption styles referenced to type volcanoes (e.g. Plinian, Strombolian, Vulcanian; this approach implicitly assumes that common processes underpin volcanic activity and can be used to predict the nature, extent and ensuing hazards of individual volcanoes. Actual volcanic eruptions, however, often include multiple styles, and type volcanoes may experience atypical eruptions (e.g., violent explosive eruptions of Kilauea, Hawaii1. The volcanological community is thus left with a fundamental conundrum that pits the uniqueness of individual volcanic systems against generalization of common processes. Addressing this challenge represents a major challenge to volcano research.

  11. Science development on volcanology flawed by the Spanish IGN

    2016-04-01

    Scientists performing research activities in the field of volcanology, related more specifically to volcano monitoring in the Canary Islands, recently discovered that not all seismic events that occurred in the country had been listed in the Spanish National Seismic Catalogue and its related data base. The National Geographic Institute (IGN) is the legal Spanish institution in-charge of the National Seismic Catalogue, together with volcanic surveillance in Spain. It was therefore a huge surprise to discover that the number of seismic events registered in and around Tenerife Island in 2010, and according to the national catalogue, was only approximately 60, while the real number of seismic events recorded by the IGN in the region was 1,176. The existence of two different accounts of seismic activity registered by the IGN in and around Tenerife Island, keeping one for the public eye, while hiding the other one from even the scientific community, is not only illegal but also unscientific, hindering the progress of science. In addition, most importantly it is detrimental for timely forecasting of sudden/instantaneous dynamic events, such as major earthquakes and/or volcanic eruptions which might spell disaster for the population, the economy of the island, and severely impact tourism. This unethical behaviour by IGN's volcanological staff has already caused damage to open scientific discussions; a key parameter for scientific development. A scientific contribution was recently published using data from 15 years of research on diffuse CO2 emission monitoring from the summit cone of Teide volcano (Pérez et al., 2013). The seismic data that was used to discuss the observed temporal variations of the degassing pattern from Teide volcano came from the National Seismic Catalogue. In contrast it is obvious that the observed variations on diffuse CO2 emission from Teide volcano from 1997 to 2011 provided a better scientific explanation when using the real seismic data that

    The increasing prevalence of digital instrumentation in volcanology and rock physics is leading to a wealth of data, which in turn is increasing the need for computational analyses and models. Today, these are largely developed by each individual or researcher. The introduction of a shared library that can be used for this purpose has several benefits: 1. when an existing function in the library meets a need recognised by a researcher it is usually much less effort than developing ones own code; 2. once functions are established and multiply used they become better tested, more reliable and eventually trusted by the community; 3. use of the same functions by different researchers makes it easier to compare results and to compare the skill of rival analysis and modelling methods; and 4. in the longer term the cost of maintaining these functions is shared over a wide community and they therefore have greater duration. Python is a high-level interpreted programming language, with capabilities for object-oriented programming. Often scientists choose this language to program their programs because of the increased productivity it provides. Although, there are many software tools available for interactive data analysis and development, there are not libraries designed specifically for volcanology and rock physics data. Therefore, we propose a new Python open-source toolbox called "VarPy" to facilitate rapid application development for rock physicists and volcanologists, which allow users to define their own workflows to develop models, analyses and visualisations. This proposal is triggered by our work on data assimilation in the NERC EFFORT (Earthquake and Failure Forecasting in Real Time) project, using data provided by the NERC CREEP 2 experimental project and volcanic experiments from INVG observatory Etna and IGN observatory Hierro as a test cases. In EFFORT project we are developing a scientist gateway which offers services for collecting and sharing volcanology

    Integrated volcanological-probabilistic approaches has been used in order to simulate pyroclastic density currents and fallout and produce hazard maps for Campi Flegrei and Somma Vesuvius areas. On the basis of the analyses of all types of pyroclastic flows, surges, secondary pyroclastic density currents and fallout events occurred in the volcanological history of the two volcanic areas and the evaluation of probability for each type of events, matrixs of input parameters for a numerical simulation have been performed. The multi-dimensional input matrixs include the main controlling parameters of the pyroclasts transport and deposition dispersion, as well as the set of possible eruptive vents used in the simulation program. Probabilistic hazard maps provide of each points of campanian area, the yearly probability to be interested by a given event with a given intensity and resulting demage. Probability of a few events in one thousand years are typical of most areas around the volcanoes whitin a range of ca 10 km, including Neaples. Results provide constrains for the emergency plans in Neapolitan area.

    Volcanic activity is an excellent hook for engaging college and university students in geoscience classes. An increasing number of Internet-accessible real-time and near–real time volcano monitoring data are now available and constitute an important resource for geoscience education; however, relatively few data sets are comprehensive, and many lack background information to aid in interpretation. In response to the need for organized, accessible, and well-documented volcano education resources, the U.S. Geological Survey's Hawaiian Volcano Observatory (HVO), in collaboration with NASA and the University of Hawai`i at Manoa, established the Volcanoes Exploration Project: Pu`u `Ō`ō (VEPP). The VEPP Web site (http://vepp.wr.usgs.gov) is an educational resource that provides access, in near real time, to geodetic, seismic, and geologic data from the active Pu`u `Ō`ō eruptive vent on Kilauea volcano, Hawaii, along with background and context information. A strength of the VEPP site is the common theme of the Pu`u `Ō`ō eruption, which allows the site to be revisited multiple times to demonstrate different principles and integrate many aspects of volcanology.

  18. Punctuated Evolution of Volcanology: An Observatory Perspective

    Burton, W. C.; Eichelberger, J. C.

    2010-12-01

    Volcanology from the perspective of crisis prediction and response-the primary function of volcano observatories-is influenced both by steady technological advances and singular events that lead to rapid changes in methodology and procedure. The former can be extrapolated somewhat, while the latter are surprises or shocks. Predictable advances include the conversion from analog to digital systems and the exponential growth of computing capacity and data storage. Surprises include eruptions such as 1980 Mount St Helens, 1985 Nevado del Ruiz, 1989-1990 Redoubt, 1991 Pinatubo, and 2010 Eyjafjallajokull; the opening of GPS to civilian applications, and the advent of an open Russia. Mount St Helens switched the rationale for volcanology in the USGS from geothermal energy to volcano hazards, Ruiz and Pinatubo emphasized the need for international cooperation for effective early warning, Redoubt launched the effort to monitor even remote volcanoes for purposes of aviation safety, and Eyjafjallajokull hammered home the need for improved ash-dispersion and engine-tolerance models; better GPS led to a revolution in volcano geodesy, and the new Russian Federation sparked an Alaska-Kamchatka scientific exchange. The pattern has been that major funding increases for volcano hazards occur after these unpredictable events, which suddenly expose a gap in capabilities, rather than out of a calculated need to exploit technological advances or meet a future goal of risk mitigation. It is up to the observatory and national volcano hazard program to leverage these sudden funding increases into a long-term, sustainable business model that incorporates both the steadily increasing costs of staff and new technology and prepares for the next volcano crisis. Elements of the future will also include the immediate availability on the internet of all publically-funded volcano data, and subscribable, sophisticated hazard alert systems that run computational, fluid dynamic eruption models.

  20. Progress in 1988 1990 with computer applications in the ``hard-rock'' arena: Geochemistry, mineralogy, petrology, and volcanology

    Science.gov (United States)

    Rock, Nicholas M. S.

    This review covers rock, mineral and isotope geochemistry, mineralogy, igneous and metamorphic petrology, and volcanology. Crystallography, exploration geochemistry, and mineral exploration are excluded. Fairly extended comments on software availability, and on computerization of the publication process and of specimen collection indexes, may interest a wider audience. A proliferation of both published and commercial software in the past 3 years indicates increasing interest in what traditionally has been a rather reluctant sphere of geoscience computer activity. However, much of this software duplicates the same old functions (Harker and triangular plots, mineral recalculations, etc.). It usually is more efficient nowadays to use someone else's program, or to employ the command language in one of many general-purpose spreadsheet or statistical packages available, than to program a specialist operation from scratch in, say, FORTRAN. Greatest activity has been in mineralogy, where several journals specifically encourage publication of computer-related activities, and IMA and MSA Working Groups on microcomputers have been convened. In petrology and geochemistry, large national databases of rock and mineral analyses continue to multiply, whereas the international database IGBA grows slowly; some form of integration is necessary to make these disparate systems of lasting value to the global "hard-rock" community. Total merging or separate addressing via an intelligent "front-end" are both possibilities. In volcanology, the BBC's videodisk Volcanoes and the Smithsonian Institution's Global Volcanism Project use the most up-to-date computer technology in an exciting and innovative way, to promote public education.

  1. Some major problems with existing models and terminology associated with kimberlite pipes from a volcanological perspective, and some suggestions

    Five significant problems hinder advances in understanding of the volcanology of kimberlites: (1) kimberlite geology is very model driven; (2) a highly genetic terminology drives deposit or facies interpretation; (3) the effects of alteration on preserved depositional textures have been grossly underestimated; (4) the level of understanding of the physical process significance of preserved textures is limited; and, (5) some inferred processes and deposits are not based on actual, modern volcanological processes. These issues need to be addressed in order to advance understanding of kimberlite volcanological pipe forming processes and deposits. The traditional, steep-sided southern African pipe model (Class I) consists of a steep tapering pipe with a deep root zone, a middle diatreme zone and an upper crater zone (if preserved). Each zone is thought to be dominated by distinctive facies, respectively: hypabyssal kimberlite (HK, descriptively called here massive coherent porphyritic kimberlite), tuffisitic kimberlite breccia (TKB, descriptively here called massive, poorly sorted lapilli tuff) and crater zone facies, which include variably bedded pyroclastic kimberlite and resedimented and reworked volcaniclastic kimberlite (RVK). Porphyritic coherent kimberlite may, however, also be emplaced at different levels in the pipe, as later stage intrusions, as well as dykes in the surrounding country rock. The relationship between HK and TKB is not always clear. Sub-terranean fluidisation as an emplacement process is a largely unsubstantiated hypothesis; modern in-vent volcanological processes should initially be considered to explain observed deposits. Crater zone volcaniclastic deposits can occur within the diatreme zone of some pipes, indicating that the pipe was largely empty at the end of the eruption, and subsequently began to fill-in largely through resedimentation and sourcing of pyroclastic deposits from nearby vents.

    FUTURVOLC is a collaborative project funded through a FP7 Environment 'supersite' call of the European Union, with 26 partners in 10 countries. The main objectives of FUTUREVOLC are to establish an integrated volcanological monitoring procedure, develop new methods to evaluate volcanic crises, increase scientific understanding of magmatic processes and improve delivery of relevant information to civil protection and authorities. To reach these objectives the project combines broad expertise in seismology, volcano deformation, volcanic gas and geochemistry, infrasound, eruption monitoring, physical volcanology, satellite studies of plumes, meteorology, ash dispersal forecasting, and civil protection. The consortium members together with a more extensive group of collaborators, has applied to CEOS for making the Iceland volcanoes a permanent geohazard supersite. In summer 2013 FUTUREVOLC partners improved volcano monitoring in Iceland by installing new equipment, including seismometers, GPS receivers, an infrasound array, and electrical sensors. A key element of the project is to combine Icelandic ground based monitoring data with satellite observations in an improved manner. This applies to different disciplines, including e.g. deformation from ground observations and InSAR, and quantification of volcanic ash clouds during eruptions by combining measurements from ground based infrared (IR) cameras and satellite microwave and IR detectors. The FUTUREVOLC project has open data policy for real-time data streams, near real-time data and science products. Implementation of a data hub will begin in 2013 with making available data for the 2010 Eyjafjallajökull eruption. Access of monitoring data through one common interface will allow timely information on magma movements from combined interpretation of relocated earthquake sources, magma sources inferred from ground and space geodetic data, and measurements of volcanic volatiles. For better response during eruptions, the

    Archean calderas provide valuable insight into internal geometries of subaqueous calderas. The New Senator caldera, Abitibi greenstone belt, Canada, is an Archean example of a subaqueous nested caldera with a basal stratigraphy dominated by gabbro-diorite dykes and sills, ponded magmas and basalt and andesite lava flows. The aim of our study is to focus on the use of physical volcanology to differentiate between the various mafic units found at the base of the New Senator caldera. Differentiation between these various mafic units is important from an exploration point of view because in modern subaqueous summit calders (e.g. Axial Seamount) margins of ponded magmas are often sites of VMS formation.

    Volcanology in Italy and in the world has rapidly developed during last decades. In the Seventies, stratigraphy and petrology provided the basic knowledge on the volcanic activities that still forms the root for modern volcano research. During the Eighties and Nineties the interest was more on the quantitative description of the volcanic processes, with enormous progresses in different but complementary fields including laboratory measurements and experiments, physico-mathematical modeling and numerical simulations, geophysical surveys and inverse analysis, and volcano monitoring and surveillance. In year 2000 a large number of magma properties and magmatic and volcanic processes was characterized at a first or higher order. Volcano research in Italy during the first decade of the new millennium has further developed along those lines. To-date, the very high risk Campi Flegrei and Vesuvius volcanoes, and the less risky but permanently active Etna and Stromboli volcanoes, are among the best monitored and more deeply investigated worldwide. The last decade has also seen coordinated efforts aimed at exploring exploitation of knowledge and skills for the benefit of the society. A series of projects focused on volcanic hazard and risk have joined >1000 researchers from Italian and foreign (Europe, US, Japan) Universities and Research Centers, on themes and objectives jointly defined by scientists from INGV and end-users from the national Civil Protection Department. These projects provide a global picture of volcano research in year 2010, that appears to be evolving through i) further rapid developments in the fields of investigation listed above, ii) their merging into effective multidisciplinary approaches, and iii) the full inclusion of the concepts of uncertainty and probabilities in volcanic scenario predictions and hazard forecast. The latter reflects the large inaccessibility of the volcanic systems, the extreme non-linear behaviour of volcanic processes put in

    Recently, Italian newspapers reported the statements of Japanese and American volcanologists which declared the high hazard related to the future occurrence of catastrophic eruption at Vesuvius. Is this a reliable picture from scientific point of view? The evaluation of volcanic hazard is based on a general statistical law for which the chances of an eruptive event increase when energy decreases. This law is constructed on the basis of empirical data. Thus, the possibility that a plinian-like eruption occurs, for each volcano, is rare and further reduced for worst-case scenario. However, empirical data are not supported by a robust scientific theory, experimentally verifiable through an exact forecast of a long-term eruption, both in time limits and in energy. Today, the lack of paradigms able to predict in a deterministic way such a complex phenomena, limit the field of the scientists that cannot go further evaluations of a purely probabilistic nature. From this point of view volcanology cannot be considered an hard quantitative Science. The declaration according to which Vesuvius, sooner or later, will produce a catastrophic eruption, yet apparently obvious if we consider the very high degree of urbanization, is not supported by any experimentally verifiable theory. Therefore, the statement according to which Vesuvius next eruptive event will be catastrophic is false. In probabilistic terms, it is actually the least possible scenario. Recognizing the cognitive limits in this research field means to encourage research itself towards the determination of more solid paradigms, in order to get more exact forecasts about such complex phenomena. The scientific compromise of defining risk scenarios, rather than deterministic evaluations about future eruptive events, precisely reflects the limits of research that have to be contemplated even by Civil Protection. Having considered these limits, every risk scenario, even the most conservative, will be ineffective in

    Santorini, the famous stratovolcano in the Aegean Sea, erupted three time periods during the 20th century (1925-1928, 1939-1941, 1950) and since then remains dormant. This study tried to combine and evaluate new and published volcanological, petrological, geochemical, environmental and sociological data of these three phases of Santorini's activity, which practically restricted to the caldera center on the Nea Kameni Islet. After field work on the formed dacite flows, pyroclastics and domes, representative rock samples and enclaves were collected and investigated for their texture, physical parameters, mineralogy and chemical composition by polarizing light microscope, scanning electron microscope (SEM-EDS), XRD, Raman spectroscopy and ICP-MS. The petrogenetic evaluation of the data obtained suggests slight but significant changes in the solid and aerial phases produced during the three explosion stages, which can be attributed to minor variations in the magmatic differentiation and magma chamber physicochemical conditions. These variations were also expressed by decrease of duration and intensity of the eruptions, as well as in their volume of ejecta and lava. Probably, the subsequent relatively long dormant period of the volcano is also related to this tension of decrease. The first compared results were collected from scientific literature, old photos as well as local and regional press and state documents from the different periods of volcanism, record the past hazard case scenarios and civil defense planning of the individual eruptions. As part of the disaster management a pilot survey, in which personal interviews with aged local islanders that were eye-witnesses of the events and elderly people or tourists that they indirectly experienced or have heard about them, was also conducted. This event-tracing, along with air pollution software models using volcanological data have shown the social impacts and the environmental consequences of the volcanic

    In the last years, it has been clearly shown how the multiparametric approach is the winning strategy to investigate the complex dynamics of the volcanic systems. This involves the use of different sensor networks, each one dedicated to the acquisition of particular data useful for research and monitoring. The increasing interest devoted to the study of volcanological phenomena led the constitution of different research organizations or observatories, also relative to the same volcanoes, which acquire large amounts of data from sensor networks for the multiparametric monitoring. At INGV we developed a framework, hereinafter called TSDSystem (Time Series Database System), which allows to acquire data streams from several geophysical and geochemical permanent sensor networks (also represented by different data sources such as ASCII, ODBC, URL etc.), located on the main volcanic areas of Southern Italy, and relate them within a relational database management system. Furthermore, spatial data related to different dataset are managed using a GIS module for sharing and visualization purpose. The standardization provides the ability to perform operations, such as query and visualization, of many measures synchronizing them using a common space and time scale. In order to share data between INGV observatories, and also with Civil Protection, whose activity is related on the same volcanic districts, we designed a "Master View" system that, starting from the implementation of a number of instances of the TSDSystem framework (one for each observatory), makes possible the joint interrogation of data, both temporal and spatial, on instances located in different observatories, through the use of web services technology (RESTful, SOAP). Similarly, it provides metadata for equipment using standard schemas (such as FDSN StationXML). The "Master View" is also responsible for managing the data policy through a "who owns what" system, which allows you to associate viewing/download of

    The lavas of the Deccan Volcanic Province (DVP), India, were erupted across the Cretaceous-Tertiary boundary (KTB) and, as such, have been suggested as a candidate for causing the KTB mass extinction event. Understanding the development of such large outpourings of lava is essential to deducing their environmental impact. Detailed flow-by-flow logging was undertaken along four roads up the Mahabaleshwar Plateau, and a further three road sections to the north and south were investigated in order to study the volcanological style of this area of the DVP. Logging along the four roads which ascend the Mahabaleshwar Plateau was combined with detailed geochemical and paleomagnetic sampling and provides the first integrated study of its kind in the DVP. The logging demonstrated that almost all the lavas encountered were inflated pahoehoe sheet lobes. No `a'a flows were encountered and one rubbly pahoehoe flow may have been observed. Statistical analyses of XRF trace element data, and the occurrence of differing thicknesses and numbers of lava units between the paleomagnetic reversal horizon (Chron 29r/29n) and the top of the Ambenali Formation, suggest that individual sheet lobes are not greater than the width of the Plateau c. 20 km. This provides an explanation for the topography, up to 95 m in our study area, on the surface of the DVP at the time when the lavas were being erupted. As the sheet lobes were emplaced and inflated they left areas uncovered by lava, the topographic difference between these two areas could be many 10s of metres, and as this process occurred over the whole DVP the topographic differences could increase. As well as topography, this leads to other complexities. When later lavas in-fill these depressions it causes them to occur physically lower in the sequence than older lavas. This demonstrates that the previously held concept of large, flat-lying sheets lobes covering vast tracts of the province is not probable, as on the local scale tracing

    Full Text Available The VST02 cruise carried out in the summer of 2002 was focused at sedimentologic and volcanologic researches over selected areas of the deep portion of the Tyrrhenian sea. Chirp lines and seafloor samples were collected from the Calabrian slope surrounding Stromboli island, in the Marsili deep sea fan, in the Vavilov basin and in the Vavilov seamount. Submarine volcanic activity, both explosive and effusive, is occuring in the Stromboli edifice. Explosive submarine volcanism affects also the shallowest areas of the Vavilov seamount. Submarine carbonate lithification has been observed on the sediment-starved flanks of the Vavilov seamount. Acoustic transparent layers make up the recentmost infill of the Gortani basin, the easternmost portion of the Vavilov basin. Channels comprised of a variety of architectural elements and depositional lobes are the main elements of the Marsili deep-sea fan where, apparently, sedimentation occurs mainly through debris flow processes.

  11. VIDEOGRAMMETRIC RECONSTRUCTION APPLIED TO VOLCANOLOGY: PERSPECTIVES FOR A NEW MEASUREMENT TECHNIQUE IN VOLCANO MONITORING

    Full Text Available This article deals with videogrammetric reconstruction of volcanic structures. As a first step, the method is tested in laboratory. The objective is to reconstruct small sand and plaster cones, analogous to volcanoes, that deform with time. The initial stage consists in modelling the sensor (internal parameters and calculating its orientation and position in space, using a multi-view calibration method. In practice two sets of views are taken: a first one around a calibration target and a second one around the studied object. Both sets are combined in the calibration software to simultaneously compute the internal parameters modelling the sensor, and the external parameters giving the spatial location of each view around the cone. Following this first stage, a N-view reconstruction process is carried out. The principle is as follows: an initial 3D model of the cone is created and then iteratively deformed to fit the real object. The deformation of the meshed model is based on a texture coherence criterion. At present, this reconstruction method and its precision are being validated at laboratory scale. The objective will be then to follow analogue model deformation with time using successive reconstructions. In the future, the method will be applied to real volcanic structures. Modifications of the initial code will certainly be required, however excellent reconstruction accuracy, valuable simplicity and flexibility of the technique are expected, compared to classic stereophotogrammetric techniques used in volcanology.

    The Reale Osservatorio Vesuviano (ROV), historic home of the Istituto Nazionale di Geofisica e Vulcanologia (INGV), is the oldest volcanological observatory in the world. It was founded in 1841 by the Bourbon king of Naples. The building is located on the western slope of Mount Vesuvius, one of the most famous and dangerous volcanoes in the world. Since its foundation, the ROV has always attracted researchers, visitors and students from many countries. The ROV site is an elegant neo-classical building which at present hosts permanent exhibitions of part of its inheritance of valuable mineral, scientific instrument and art collections. A radical change is now under way, starting with the structural reinforcement of the building, renewal and upgrading of services, and the redefinition of exhibition itineraries so as to make visits still more enjoyable and informative. This will include the integration of outdoor footpaths and theme-based routes designed for users of differing levels of expertise. This major transformation also involves a study and a number of operations aimed at the possibility of developing self-financed activities. To this end an analysis of tourist movements in Campania was conducted, in part so as to attract to the ROV a larger and more varied group of visitors. In an area that - despite its unique characteristics - is currently significantly degraded and underused, the creation of such a powerful tourist and cultural attraction would serve as a focus for the development of additional activities and services that would greatly enhance it and stimulate growth. These activities would, of course, be compatible with a territory that has a high risk of volcanic hazards - indeed, such growth would constitute an important component in mitigating this risk in the area. The example given illustrates how the restoration and enhancement of a piece of our historic, scientific and cultural heritage could be the driving force behind the economic revival of an

    Vulcano and Stromboli are the most active volcanoes of the Aeolian Islands. Vulcano is quiescent since the eruption of 1888-90 but in the last decades it experienced several crises with huge increase of gas output and temperature of the crater fumaroles, and variations in the magmatic gas components. Stromboli is characterized by a permanent mild explosive activity, episodically interrupted by major explosions, lava effusions, or paroxystic explosive events (October 2001: a tourist killed; December 2002: lava effusion, tsunami generated by flank collapse; April 2003: explosive paroxysm, block fallout on Ginostra village; February-March 2007: lava effusion and paroxysm). These islands are renowned tourist sites for the marvelous sea and the fascination that the volcanoes evoke. In fact, during summer risk increases as there are 10,000-15,000 persons per island (only a few hundreds in winter). Starting from the 1990 the INGV and the Civil Protection established a Volcanological Information Centre on each island with the main goal to inform population and tourists on the risks related to each volcano. During the year the two centres are visited by 8000-10,000 visitors coming from different countries. Researchers and trained students are involved in the educational activity devoted to inform visitors on the scientific aspects of volcano monitoring and hazard assessment and to ensure that tourists, willing to climb the summit crater area, will behave properly. In 2008 the Vulcano exhibition has been totally restyled. The INGV Laboratorio Grafica e Immagini has created for the project a composite and innovative graphic study. This includes a series of products (logos, brochures, panels ecc) with the intent to create new effective information means. The logo creation has been the first step for all the communications: an image with strong impact on volcano information distributed in strategic zones of the village to stimulate interest in the INGV centre and its exhibition.

    The VIDA Framework as an Education Tool: Leveraging Volcanology Data for Educational Purposes Dohy Faied, Aurora Sanchez (on behalf of SSP08 VAPOR Project Team) While numerous global initiatives exist to address the potential hazards posed by volcanic eruption events and assess impacts from a civil security viewpoint, there does not yet exist a single, unified, international system of early warning and hazard tracking for eruptions. Numerous gaps exist in the risk reduction cycle, from data collection, to data processing, and finally dissemination of salient information to relevant parties. As part of the 2008 International Space University's Space Studies Program, a detailed gap analysis of the state of volcano disaster risk reduction was undertaken, and this paper presents the principal results. This gap analysis considered current sensor technologies, data processing algorithms, and utilization of data products by various international organizations. Recommendations for strategies to minimize or eliminate certain gaps are also provided. In the effort to address the gaps, a framework evolved at system level. This framework, known as VIDA, is a tool to develop user requirements for civil security in hazardous contexts, and a candidate system concept for a detailed design phase. While the basic intention of VIDA is to support disaster risk reduction efforts, there are several methods of leveraging raw science data to support education across a wide demographic. Basic geophysical data could be used to educate school children about the characteristics of volcanoes, satellite mappings could support informed growth and development of societies in at-risk areas, and raw sensor data could contribute to a wide range of university-level research projects. Satellite maps, basic geophysical data, and raw sensor data are combined and accessible in a way that allows the relationships between these data types to be explored and used in a training environment.

    Probabilistic approaches based on available volcanological data from real eruptions of Campi Flegrei and Somma-Vesuvius, are assembled in a comprehensive assessment of volcanic hazards at the Neapolitan area. This allows to compare the volcanic hazards related to the different types of events, which can be used for evaluating the conditional probability of flows and falls hazard in case of a volcanic crisis. Hazard maps are presented, based on a rather complete set of numerical simulations, produced using field and laboratory data as input parameters relative to a large range (VEI 1 to 5) of fallout and pyroclastic-flow events and their relative occurrence. The results allow us to quantitatively evaluate and compare the hazard related to pyroclastic fallout and density currents (PDCs) at the Neapolitan volcanoes and their surroundings, including the city of Naples. Due to its position between the two volcanic areas, the city of Naples is particularly exposed to volcanic risk from VEI>2 eruptions, as recorded in the local volcanic succession. Because dominant wind directions, the area of Naples is particularly prone to fallout hazard from Campi Flegrei caldera eruptions in the VEI range 2-5. The hazard from PDCs decreases roughly radially with distance from the eruptive vents and is strongly controlled by the topographic heights. Campi Flegrei eruptions are particularly hazardous for Naples, although the Camaldoli and Posillipo hills produce an effective barrier to propagation to the very central part of Naples. PDCs from Vesuvius eruptions with VEI>4 can cover the city of Naples, whereas even VEI>3 eruptions have a moderate fallout hazard there.

    Tephra fall is a relevant hazard of Campi Flegrei caldera (Southern Italy), due to the high vulnerability of Naples metropolitan area to such an event. Here, tephra derive from magmatic as well as phreatomagmatic activity. On the basis of both new and literature data on known, past eruptions (Volcanic Explosivity Index (VEI), grain size parameters, velocity at the vent, column heights and erupted mass), and factors controlling tephra dispersion (wind velocity and direction), 2D numerical simulations of fallout dispersion and deposition have been performed for a large number of case events. A bayesian inversion has been applied to retrieve the best values of critical parameters (e.g., vertical mass distribution, diffusion coefficients, velocity at the vent), not directly inferable by volcanological study. Simulations are run in parallel on multiple processors to allow a fully probabilistic analysis, on a very large catalogue preserving the statistical proprieties of past eruptive history. Using simulation results, hazard maps have been computed for different scenarios: upper limit scenario (worst-expected scenario), eruption-range scenario, and whole-eruption scenario. Results indicate that although high hazard characterizes the Campi Flegrei caldera, the territory to the east of the caldera center, including the whole district of Naples, is exposed to high hazard values due to the dominant westerly winds. Consistently with the stratigraphic evidence of nature of past eruptions, our numerical simulations reveal that even in the case of a subplinian eruption (VEI = 3), Naples is exposed to tephra fall thicknesses of some decimeters, thereby exceeding the critical limit for roof collapse. Because of the total number of people living in Campi Flegrei and the city of Naples (ca. two million of inhabitants), the tephra fallout risk related to a plinian eruption of Campi Flegrei largely matches or exceeds the risk related to a similar eruption at Vesuvius.

    Paraná-Etendeka volcanism led to the opening of the Atlantic Ocean during the early Cretaceous. Most Paraná research has focused on the regional scale geochemistry and geochronology. Complementarily, we have taken a physical volcanological approach to elucidate the styles and locations of silicic eruptions with a focus on extrusive vs. explosive varieties, and an ultimate goal to characterise the crustal magmatic conditions. Through satellite to microscopic observations we can zoom from volcanic edifice and deposit morphologies, remarkably preserved in the Mesozoic landscape, to primary microscopic textures. Lava domes appear in clusters with high relief and are surrounded by lower flat-topped terraces comprised of multiple tabular-shaped packages with conspicuous horizontal jointing. Joint thickness coincides with layering from mm-scale laminations to larger lens-shaped blobs up to 20 cm thick and more than a metre long. These layered deposits appear to be compressed and/or stretched into the finer laminations and grade up into the fatter lens-shaped blobs. In other regions, extensive plateaus dominate the landscape with flat-lying flow packages continuous over 10's of kilometres and possibly further. Rheomorphism is evident in places with sub-parallel joints that grade up into a zone of deformation where curvilinear to overturned joint patterns reflect lateral forcing in a more ductile flow regime. Microscopically the blobs and surrounding matrix are almost indistinguishable except for subtle differences in spherulite textures, zonal alteration and distribution of crystal sizes. Although our research is relatively nascent, our observations suggest eruptions may have ranged from edifice building effusive ones to more explosive ones, albeit possibly relatively low fire fountains feeding hybridised lava/pyroclastic flows. Some of these flows are extensive, tens to possibly hundreds of kilometres long, consistent with high eruption rates of hot magma. These

    Continental flood basalt lava flows are widely assumed to represent compositionally uniform and rapidly erupted products of large well-mixed magma reservoirs. However, this study presents new data to illustrate systematic element and isotope variations within the flow field formed by an individual flood basalt eruption, both vertically within each sheet lobe and laterally between the constituent lobes. Such variation is significant in chemostratigraphic correlation of flood basalt lava units, in identifying source variability during one eruption, and in petrogenetic modeling. We investigate the extent and cause of compositional variation through tracing lava sheet lobes in a 2,660 cubic kilometer pahoehoe flow field formed during a single eruption in the Columbia River Basalt Province, USA. This is based on features related to emplacement by the inflation mechanism. This method of emplacement is supported by small but statistically significant and systematic major and trace element variation e.g. MgO 3.09- 4.55 wt%, Ni 17.5-25.6 ppm, indicative of fractional crystallisation. Re-Os isotopes indicate progressive crustal contamination of the magma over the timescale of a single flood basalt eruption. By establishing this physical volcanological framework, we determine a temporal link with the supply of lava from the vent(s) and apply it to investigate sequential magmatic evolution during the timescale of one eruption.

    The study reports the basic physical volcanological and stratigraphical features of a hitherto unrecognized silicic phreatomagmatic fall succession from the Bükk Foreland Volcanic Area (Hungary), known as part of the extensive Miocene ignimbrite volcanism of the northern CPR. The complex have been identified at two sites, in the vicinity of Bogács and Tibolddaróc villages. Tens of mm to several dm thick layers make up the 20 m thick entire succession. The complex could be subdivided into three eruption cycles by two, intercalated well-developed paleosoil horizons, which indicate longer repose periods. The eruption cycles consist of several individual eruptive events. The volcano-sedimentological field approach was completed by granulometrical and low field anisotropy of magnetic susceptibility (AMS) studies. Combined dry sieving and laser diffraction particle size analysis were performed to get information on median grain size (MdΦ) and sorting (σΦ) of friable layers. AMS was used to infer the emplacement processes. Based on the following features the succession is proposed to record a large-scale, silicic, phreatomagmatic fall activity: i) Presence of very fine ash and abundant ash aggregates, ii) General poor sorting, and often bimodal grain-size distributions; ii) Extremely weak magnetic fabric compared to dilute, thin pyroclastic density current deposits. On the basis of comparison of the recorded grain size characteristics with data from other silicic phretomagmatic fall deposits worldwide, several units in the succession can be considered as phreatoplinian fall deposit (sensu lato), described for the first time in the CPR.

To improve the sensitivity and reduce ambient noise, special efforts were made to enhance the design of the seismic vault and the original Stuttgart shielding (D. Kurrle R. Widmer-Schnidrig, 2005) of the broadband seismometers (240 and 120 sec). This renewed network feeds the Caribbean Tsunami Warning System supported by UNESCO and establishes a monitoring tool that produces high quality data for studying subduction and volcanism interactions in the Lesser Antilles arc. Since 2010, the UnderVolc research program has been an opportunity to reinforce the existing volcanic seismic network of Piton de la Fournaise on La Réunion Island (Indian Ocean). 20 broadband seismometers, 20 short-period sensors, and 26 GNSS receivers now cover the volcano. The program successfully developed many new data treatment tools. They have proven to be well-adapted for monitoring volcanic activity such as the tracking of seismic velocity changes inferred from seismic noise, or the injection of dike and the resulting deformations. This upgrade has now established the monitoring network of La Réunion hot spot to high quality standards which will foster the scientific attractiveness of OVPF-IPGP. During

    The density of any material imposes a primary control upon its potential or actual physical behaviour in relation to its surrounds. It follows that a thorough understanding of the physical behaviour of dynamic, multi-component systems, such as active volcanoes, requires knowledge of the density of each component. If we are to accurately predict the physical behaviour of synthesized or natural volcanic systems, quantitative densiometric measurements are vital. The theoretical density of melt, crystals and bubble phases may be calculated using composition, structure, temperature and pressure inputs. However, measuring the density of natural, non-ideal, poly-phase materials remains problematic, especially if phase specific measurement is important. Here we compare three methods; Archimedes principle, He-displacement pycnometry and X-ray micro computed tomography (XMT) and discuss the utility and drawbacks of each in the context of modern volcanologic study. We have measured tephra, ash and lava from the 934 AD Eldgjá eruption (Iceland), and the 2010 AD Eyjafjallajökull eruption (Iceland), using each technique. These samples exhibit a range of particle sizes, phases and textures. We find that while the Archimedes method remains a useful, low-cost technique to generate whole-rock density data, relative precision is problematic at small particles sizes. Pycnometry offers a more precise whole-rock density value, at a comparable cost-per-sample. However, this technique is based upon the assumption pore spaces within the sample are equally available for gas exchange, which may or may not be the case. XMT produces 3D images, at resolutions from nm to tens of µm per voxel where X-ray attenuation is a qualitative measure of relative electron density, expressed as greyscale number/brightness (usually 16-bit). Phases and individual particles can be digitally segmented according to their greyscale and other characteristics. This represents a distinct advantage over both

    The physical volcanology and morphometric analyses of pillowed lava flows from the Chitradurga basin of Chitradurga Greenstone Belt, South India have been undertaken. In the Chitradurga hills individual pillowed flows alternate with massive submarine sheet flows. The pillows from such flows are separated by chert and occur as spheroidal, elongated or reniform units that are devoid of vesicles, vesicle bands or pipe vesicles. The Mardihalli flow is exposed as a small elongated mound in the basin and consists of a massive core that is draped by pillows along the flow crest and flanks. The pillows from Mardihalli occur as spheroidal to elongate units with smooth, spalled or wrinkled surfaces with vesicular interiors. Repeated budding of larger pillows have produced a series of interconnected pillow units indicating fluid lava that was emplaced on steeply dipping flanks. Based on the morphological features the pillowed flows from the Chitradurga basin were emplaced at low effusion rates (≤ 5 m3/s). Pillows in these flows formed from low viscosity lavas that underwent negligible to moderate inflation due to rapid chilling. Sporadic occurrences of pillow breccias, hyaloclastite and chert breccias in the pillowed flow fields indicate disruption of pillows due to lava surges and slumping. It is envisaged that the Chitradurga basin witnessed distinct episodes of submarine tholeiite eruptions that produced pillowed lavas that variably interacted with sea water to produce geochemistries. The field and stratigraphic relationships of the volcanics and associated clastic sediments suggest that the pillow lavas were emplaced in a shallow marine marginal inter/back arc basin.

  3. Sustaining an Online, Shared Community Resource for Models, Robust Open source Software Tools and Data for Volcanology - the Vhub Experience

    Over the last 5 years we have created a community collaboratory Vhub.org [Palma et al, J. App. Volc. 3:2 doi:10.1186/2191-5040-3-2] as a place to find volcanology-related resources, and a venue for users to disseminate tools, teaching resources, data, and an online platform to support collaborative efforts. As the community (current active users > 6000 from an estimated community of comparable size) embeds the tools in the collaboratory into educational and research workflows it became imperative to: a) redesign tools into robust, open source reusable software for online and offline usage/enhancement; b) share large datasets with remote collaborators and other users seamlessly with security; c) support complex workflows for uncertainty analysis, validation and verification and data assimilation with large data. The focus on tool development/redevelopment has been twofold - firstly to use best practices in software engineering and new hardware like multi-core and graphic processing units. Secondly we wish to enhance capabilities to support inverse modeling, uncertainty quantification using large ensembles and design of experiments, calibration, validation. Among software engineering practices we practice are open source facilitating community contributions, modularity and reusability. Our initial targets are four popular tools on Vhub - TITAN2D, TEPHRA2, PUFF and LAVA. Use of tools like these requires many observation driven data sets e.g. digital elevation models of topography, satellite imagery, field observations on deposits etc. These data are often maintained in private repositories that are privately shared by "sneaker-net". As a partial solution to this we tested mechanisms using irods software for online sharing of private data with public metadata and access limits. Finally, we adapted use of workflow engines (e.g. Pegasus) to support the complex data and computing workflows needed for usage like uncertainty quantification for hazard analysis using physical

    Eruptions come in a range of magnitudes. Numerical simulations and laboratory experiments show that rare, giant super-eruptions and smaller, more frequent events reflect a transition in the essential driving forces for volcanism.

  18. The VEI-7 Millennium eruption, Changbaishan-Tianchi volcano, China/DPRK: New field, petrological, and chemical constraints on stratigraphy, volcanology, and magma dynamics

    Field relations, petrography, bulk and micro-scale chemistry reveal that the most recent history of hazardous Changbaishan-Tianchi volcano should be revised with important implications for volcanic hazard in NE Asia. Currently, the two most recent large eruptions are identified separately as a VEI 5 trachytic Baguamiao eruption (BGM) and the much heralded VEI 7, late 946 CE (Common Era) "Millennium" eruption (ME) of comendite. However, we find that the former is part of the latter based on the following evidence: (1) trachytic fallout of the BGM lies directly on the comendite tephra of the ME without any indication of depositional hiatus; (2) abundant mingled trachyte-comendite pumice in the tephra deposits; (3) similar chemistry of mingled pumice and its components to those in the BGM and ME products; (4) correlation of bimodal glass shard compositions in the distal 'B-Tm' ash from the Japan Sea with comendite and trachyte glass from the BGM and ME products. Based on the above evidence, we suggest that the great Millennium eruption of 946 CE should be revised finally to include the BGM trachyte as its final stage. Furthermore, deposits attributed to two other trachytic eruptions in 1668 and/or 1702 CE (also called Baguamiao by some authors), and 1903 CE referred to in historic accounts were also examined. Our field observations, petrography, bulk and micro-scale chemistry combined with previously published Ra/Th ages indicate that all these trachytes are either primary deposits of the ME or its reworked deposits. Thus our findings do not support two separate post-ME eruptions and require that volcanic hazard assessment at Changbaishan volcano include this new interpretation. Recently published geochronological data integrated with our new petrochemical and volcanological framework informs the magma dynamics leading to the ME. The ME comendite, derived from a parental trachyte similar to the BGM started accumulating at shallow levels around 12 ka to 8 ka. Around 4

    In this paper the application of the Synthetic Aperture Radar Interferometry (INSAR) on volcanology is analysed. Since it is not a real novelty among the different applications of INSAR in Earth Observation activities, at the beginning of this paper it is analysed the state of the art of the researches in this field. During the discussion, the point of view of volcanologists is favoured because it is considered that the first applications were often badly aimed. Consequently, the initial INSAR performances in volcanology were overrated with respect to the real capabilities of this technique. This fact lead to discover some unexpected limitations in INSAR usage in volcano monitoring, but, at the same time, spurred on scientists to overcome these drawbacks. The results achieved recently allow to better apply SAR to volcanology; in the paper a possible operative work-plan aimed at introducing INSAR in the volcano monitoring system is presented.

    Historically, significant advances in volcanology have been catalyzed by volcanic disasters or crises, reflecting the the simple fact that volcanoes seem to receive serious scientific and public attention only when they cause, or threaten to cause, trouble. For example, three deadly eruptions in 1902, Mount Pelee, Santa Maria, and Soufriere (St.Vincent), spurred the movement to establish permanent volcano observatories there. Profoundly impresses by the devastation cused by Mont Pelee, Thomas A. Jaggar, Jr. founded the Hawaiian Volcano Observatory (HVO) in 1912. Since then, studies conducted at HVO and new observatories have been pivotal in transforming the nascent science of volcanology into the multidisciplinary science that it is today.

    DEFF Research Database (Denmark)

    Iceland is one of the most active terrestrial volcanic regions on Earth with an average of more than 20 eruptions per century. Around 80% of all events are tephra generating explosive eruptions, but less than 10 % of all known tephra layers have been mapped. Recent hazard assessment models show...... that the two key parameters for hazard assessment modeling are total grain size distribution (TGSD) and eruptive style. These two parameters have been determined for even fewer eruptive events in Iceland. One of the most hazardous volcanoes in Iceland is Katla and no data set of TGSD or other eruptive...... parameters exist. Katla has not erupted for 99 years, but at least 2 of the 20 eruptions since the settlement of Iceland in 871 have reached Northern Europe as visible tephra fall. These eruptions occurred in 1755 and 1625 and remain enigmatic both in terms of actual size and eruption dynamics. This work...

    There was no volcano in Precambrian and Mesozoic eras in Iran, but in most place of Iran during the next eras volcanic rocks with green series and Dacites were seen. By the recent survey in Sahand mountain in NW of Iran volcanography, determination of rocks and the age of layers were estimated. The deposits of Precambrian as sediment rocks are also seen in the same area. All of volcanic periods in this place were studied; their extrusive rocks, their petrography and the result of their analytical chemistry were discussed. Finally volcano sedimentology of Sahand mountain were described

    Full Text Available Three-dimensional reconstruction of the ground surface (Digital Terrain Model, DTM, derived by airborne GPS photogrammetric surveys, is a powerful tool for implementing morphological analysis in remote areas. High accurate 3D models, with submeter elevation accuracy, can be obtained by images acquired at photo scales between 1:5000-1:20000. Multitemporal DTMs acquired periodically over volcanic area allow the monitoring of areas interested by crustal deformations and the evaluation of mass balance when large instability phenomena or lava flows have occurred. The work described the results obtained from the analysis of photogrammetric data collected over the Vulcano Island from 1971 to 2001. The data, processed by means of the Digital Photogrammetry Workstation DPW 770, provided DTM with accuracy ranging between few centimeters to few decimeters depending on the geometric image resolution, terrain configuration and quality of photographs.

    Imaging the inner part of large geological targets is an important issue in geosciences with various applications. Different approaches already exist (e.g. gravimetry, electrical tomography) that give access to a wide range of information but with identified limitations or drawbacks (e.g. intrinsic ambiguity of the inverse problem, time consuming deployment of sensors over large distances). Here we present an alternative and complementary tomography method based on the measurement of the cosmic muons flux attenuation through the geological structures. We detail the basics of this muon tomography with a special emphasis on the photo-active detectors.

  10. Volcanology of the Alarcon Rise, Gulf of California

    Portner, R. A.; Clague, D. A.; Dreyer, B. M.; Martin, J. F.; Paduan, J. B.

    2012-12-01

    The Alarcon Rise is a ~50 km long intermediate-rate (~50mm/a) spreading center at the southern end of the Gulf of California. In Spring 2012, an MBARI-led expedition to Alarcon Rise mapped a ~1.5- 3km wide swath of the ridge axis at 1-m resolution and completed 9 dives with the ROV Doc Ricketts (Clague et al., this session). Pillow, lobate, and sheet flows occur along the entire axis. An inflated zone of the axis south of the midpoint along the Rise is dominated by a large sheet/lobate flow that erupted from en echelon fissures that extends for 8 km. This flow extends laterally away from the fissures for at least 2 km and covered nearly all prior flows and pillow mounds in its path. The middle of the segment contains a 1km across flat-topped volcano, virtually unmodified by fissures and faults, which dissect a 2.5 km across shield 5 km to the north. The NE and SW parts of the axis are characterized by more abundant pillow mounds and less voluminous sheet flows. Many of the pillow mounds, especially those in the northern third of the axis are small, steep sided mounds. Examination of sand and slit sized fractions of the basal cm of 87 cores collected by the ROV shows that basaltic pyroclasts with fluidal or bubble-wall (limu o Pele) morphologies are ubiquitous along the entire ridge. A rugged dome-like structure about 0.5x1.2kmx75m tall occurs about 9 km from the northern end of the ridge axis. Its crest is at a depth of 2330 m. Linear ridge-parallel faults and ridges cross-cut or terminate into the dome. These ridges extend several km both NE and SW along strike from the dome. Extensive sampling during two ROV dives shows that the entire dome is constructed of coarse blocky breccia and minor lineated flows of rhyolite. Dacite, andesite, and basaltic andesite flows occur on adjacent slopes to the north, south and west, and exhibit medium- to large-diameter pillow morphologies. Many of these flows and the flanks of the dome are mantled by abundant coarse- to fine-grained volcaniclastic deposits. The eastern side of the dome is onlapped by lobate and sheet basalt flows. Proximal volcaniclastic deposits contain a wide range in componentry. A notable component is comprised of a light brown glass which is brecciated and cemented by a highly vesicular clear glass mesh that contains up to ~80% vesicles. Vesicles in the mesh are locally attenuated into elongate forms along and form expansion cracks that pass through highly fragmented jig-saw fit phenocrysts. Fluidal ash shards and pumice-to scoria clasts are also present. Pelagic sediment in more distal regions contains a significant amount of finer-grained volcaniclastic material, including some thin colorless glass shards, comparable to mafic limu o Pele. The dome was probably extruded as a series of lobes accompanied by minor explosive activity as the steep flanks of the lobes collapsed. The highly vesicular and fluidal character of some of the lapilli suggests that magma degassing powered the eruption, even at 2300m depth. Foraminifera are common in all hemipelagic sediment samples and will provide a basis for radiocarbon dating. Sedimentation ages will be used in conjuncton with zircon geochronology, to constrain the timescales of dome construction and the ages of surrounding flows.

  11. Venusian channels and valleys - Distribution and volcanological implications

    Science.gov (United States)

    1993-01-01

    An updated map is presented which shows the distribution of more than 200 channels and valleys on Venus. A large number of channels are concentrated in equatorial regions characterized by highlands, rift and fracture zones, an associated volcanic features. Many channels associated with flow deposits are similar to typical terrestrial lava drainage channels. They are associated with a wide range of volcanic edifices. More than half of the sinuous rilles are associated with coronae, coronalike features, or arachnoids. Corona volcanism driven by mantle plume events may explain this association. Many valley network are observed in highlands and in association with coronae, coronalike features, or arachnoids. This indicates that highlands and coronae provided fractures and flow-viscosity lavas, both of which seem to be required for network formation by lava sapping processes. Canali-type channels have a unique distribution limited to some plains regions.

    2010-12-01

    The vigorous pursuit of submarine volcanism as a major field emerged in the mid 1900’s with the post WWII recognition that there is a Mid-Ocean Ridge System that is a 70,000 km long volcanic mountain chain stretching around the world like the strings on a baseball. By the mid 1960’s it emerged that rocks from volcanic feature were consistently basaltic in character and that they were the direct result of major melting processes associated with rise of much deeper mantle material beneath the spreading ridges in a global plate tectonics framework. More than 60% of the volcanism on the planet occurs in submarine environments. The next major discovery, using the deep diving submarine ALVIN, was in the late 1970’s involving hydrothermal systems near active ridges close to the Galapagos Islands and Baja California. The idea that these vent sites were the locus of major biological productivity based on volcanically-driven chemosynthesis was a fundamental new insight in the deep ocean ecology of our planet. This was a major planetological discovery and was followed within about 15 years with an even more powerful realization: our planet has a vast sub seafloor microbial biosphere thriving in the pores and the cracks of the oceanic crust driven by circulation of modified ocean fluids through large portions of the lithosphere. These organisms are largely supported by degassing and water-rock reactions associated with submarine volcanoes. Some estimates have posited that: 1) these thermally active systems and the chemosynthetic lifestyle are a natural consequence of certain types of planetary evolution, 2) that life may have originated in these systems, and, 3) that the biomass associated with the modern sub seafloor systems rivals most other living carbon on the continents. Indeed, parallel exploration of the outer solar system has lead to propositions that the second moon of Jupiter, Europa, has (or had) a high potential to harbor analogous hydrothermal life forms owing to the fact that it is covered with water ice and is the next door neighbor to the most volcanically active body in the solar system - Io. Future approaches to studying both terrestrial and off-planet volcanic systems will involve an increasingly sophisticated use of cutting edge technologies enabled by robotic systems, novel and mobile sensor modalities in four dimensions, very high bandwidth communication systems, power extraction from the environment, massive computational power, nanotech systems, unparalleled in situ imaging capabilities, and the capacity to support human telepresence and machine autonomy in remote environments at levels that are totally unprecedented. Earth’s oceans will be the experimental test bed for deploying and maturing these capabilities, but oceans in our solar system and beyond will become the ultimate targets for exploration of one of the ultimate questions: Are we alone

  13. Educational activities of CAREER: Crystallization Kinetics in Volcanology

    Professional development of teachers is recognized as critical for improving student learning outcomes. The major outreach initiative of my CAREER award was to develop a teacher professional development program for middle school (grades 6-8) teachers that would improve teacher's mastery of geoscience and basic science skills and practices and expose them to an authentic research environment. The explicit objectives of the Research Experience for Teachers in Volcano-Petrology (RET/V-P) were for teachers to (1) master technical skills for safe and productive laboratory work, (2) deepen understanding of science content, (3) develop scientific "habits of the mind" as outlined in the National Science Standards, and (4) hone science communication skills. Six teachers, one undergraduate, and two graduate students participated in the teacher professional development program during the summers of the CAREER award period. A subsequent EAR award now supports the program, and summer 2011 saw the participation of five additional teachers. The teachers span a wide range of educational backgrounds, prior exposure to geoscience, and teaching assignments at public and private schools. Each year, the program was modified using formative and summative evaluation tools to better serve the scheduling needs and content preferences. In general, the program has evolved from an emphasis on research exposure to an emphasis on imparting basic geoscience concepts. A myriad of approaches including field trips to local outcrops, lecture tutorials and lecture-based active engagement exercises (such as iclicker delivery of Geoscience Concept Inventory questions), with a taste of laboratory work (crystal growth experiments, optics primer), has emerged as the most successful means of achieving objectives 1-4, above. The first summer I advertised the RET/V-P, no teachers applied. (This challenge was overcome in subsequent years by targeting the solicitation using teacher list serves, the Hawaii Science Teachers Association web site, and direct email to teachers at nearby schools.) Instead, I modified the way I taught Mineralogy, using CAREER resources to implement a peer-mentoring program in which upper-level undergraduates assisted with a semester-long mineral specimen identification project. The enrolled students received an authentic discovery-based inquiry experience and were required to write and revise incremental and final reports detailing the physical (primarily optical) and chemical evidence supporting their claim. The peer-mentors benefitted from strengthened understanding of subject material and experience teaching and communicating science. A continuing challenge in implementing this and other innovative teaching strategies is obtaining the necessary institutional support in a climate of deep budget cuts. The benefits of receiving the CAREER and PECASE awards are personal and professional. The awards eased the tenure process at my institution, created opportunities to visit other institutions, and liberated me to pursue new research directions and collaborations. Implementing my educational outreach program improves my introductory-level undergraduate teaching and teaches me to communicate my research more effectively.

  14. Strategies for the implementation of a European Volcano Observations Research Infrastructure

    2015-04-01

    Active volcanic areas in Europe constitute a direct threat to millions of people on both the continent and adjacent islands. Furthermore, eruptions of "European" volcanoes in overseas territories, such as in the West Indies, an in the Indian and Pacific oceans, can have a much broader impacts, outside Europe. Volcano Observatories (VO), which undertake volcano monitoring under governmental mandate and Volcanological Research Institutions (VRI; such as university departments, laboratories, etc.) manage networks on European volcanoes consisting of thousands of stations or sites where volcanological parameters are either continuously or periodically measured. These sites are equipped with instruments for geophysical (seismic, geodetic, gravimetric, electromagnetic), geochemical (volcanic plumes, fumaroles, groundwater, rivers, soils), environmental observations (e.g. meteorological and air quality parameters), including prototype deployment. VOs and VRIs also operate laboratories for sample analysis (rocks, gases, isotopes, etc.), near-real time analysis of space-borne data (SAR, thermal imagery, SO2 and ash), as well as high-performance computing centres; all providing high-quality information on the current status of European volcanoes and the geodynamic background of the surrounding areas. This large and high-quality deployment of monitoring systems, focused on a specific geophysical target (volcanoes), together with the wide volcanological phenomena of European volcanoes (which cover all the known volcano types) represent a unique opportunity to fundamentally improve the knowledge base of volcano behaviour. The existing arrangement of national infrastructures (i.e. VO and VRI) appears to be too fragmented to be considered as a unique distributed infrastructure. Therefore, the main effort planned in the framework of the EPOS-PP proposal is focused on the creation of services aimed at providing an improved and more efficient access to the volcanological facilities

    The European volcanological community contributes to implementation of European Plate Observing System (EPOS) by making operational an integrated platform to guarantee a seamless access to the data provided by the European Solid Earth communities. To achieve this objective, the Volcano Observations Work Package (WP11) will implement a Thematic Core Services (TCS) which is planned to give access to the data and services provided by the European Volcano Observatories (VO) and some Volcanological Research Institutions (VRI; as university departments, laboratories, etc.); both types are considered as national research infrastructures (RI) over which to build the TCS. Currently, the networks on European volcanoes consist of thousands of stations or sites where volcanological parameters are continuously or periodically measured. These sites are equipped with instruments for geophysical (seismic, geodetic, gravimetric, electromagnetic), geochemical (volcanic plumes, fumaroles, groundwater, rivers, soils), environmental observations (e.g. meteorological and air quality parameters), as well as various prototypal monitoring systems (e.g. Doppler radars, ground based SAR). In Europe also operate laboratories for sample analysis (rocks, gases, isotopes, etc.), and almost continuous analysis of space-borne data (SAR, thermal imagery, SO2 and ash), as well as high-performance computing centres. All these RIs provide high-quality information (observations) on the current status of European volcanoes and the geodynamic background of the surrounding areas. The implementation of the Volcano Observations TCS is addressing technical and management issues, both considering the current heterogeneous state of the art of the volcanological research infrastructures in Europe. Indeed, the frame of the VO and VRI is now too fragmented to be considered as a unique distributed infrastructure, thus the main effort planned in the frame of the EPOS-IP is focused to create services aimed at

  14. The contribution of the Volcano Observations Work Package to the implementation of the European Plate Observing System

    2016-04-01

    The overall aim of the implementation phase of European Plate Observing System (EPOS) is to make the integrated platform operational in order to guarantee seamless access to the data provided by the European Solid Earth communities. The Volcano Observations Work Package (WP11) contributes to this objective by implementing a Thematic Core Service (TCS) which is planned to give access to the data and services provided by the European Volcano Observatories (VO) and some Volcanological Research Institutions (VRI; such as university departments, laboratories, etc.). Both types are considered as national research infrastructures (RI) which the TCS will integrate. Currently, monitoring networks on European volcanoes consist of thousands of stations or sites where volcanological parameters are continuously or periodically measured. These sites are equipped with instruments for geophysical (seismic, geodetic, gravimetric, electromagnetic), geochemical (volcanic plumes, fumaroles, groundwater, rivers, soils), environmental observations (e.g. meteorological and air quality parameters), as well as various prototypal monitoring systems (e.g. Doppler radars, ground based SAR). Across Europe several laboratories provide sample characterization (rocks, gases, isotopes, etc.), quasi-continuous analysis of space-borne data (SAR, thermal imagery, SO2 and ash), as well as high-performance computing facilities. All these RIs provide high-quality information (observations) on the current status of European volcanoes and the geodynamic background of the surrounding areas. The implementation of the Volcano Observations TCS will address technical as well as managerial issues, both considering the current heterogeneous state-of-the-art of the volcanological research infrastructures in Europe. Indeed, the current arrangement of individual VO and VRI is considered too fragmented to be considered as a unique distributed infrastructure. Therefore, the main effort in the framework of the EPOS

    Physical and numerical modelling is becoming of increasing importance in volcanology and volcanic hazard assessment. However, new interdisciplinary problems arise when dealing with complex mathematical formulations, numerical algorithms and their implementations on modern computer architectures. Therefore new frameworks are needed for sharing knowledge, software codes, and datasets among scientists. Here we present the Volcano Modelling and Simulation gateway (VMSg, accessible at http://vmsg.pi.ingv.it), a new electronic infrastructure for promoting knowledge growth and transfer in the field of volcanological modelling and numerical simulation. The new web portal, developed in the framework of former and ongoing national and European projects, is based on a dynamic Content Manager System (CMS) and was developed to host and present numerical models of the main volcanic processes and relationships including magma properties, magma chamber dynamics, conduit flow, plume dynamics, pyroclastic flows, lava flows, etc. Model applications, numerical code documentation, simulation datasets as well as model validation and calibration test-cases are also part of the gateway material.

    Magmatic degassing plays a key role in the dynamics of volcanic activity and also in contributing to the carbon, water and sulphur volatile cycles on Earth. Quantifying the fluxes of magmatic gas emitted from volcanoes is therefore of fundamental importance in Earth Science. This has been recognised since the beginning of modern volcanology, with initial measurements of volcanic SO2 flux being conducted with COrrelation SPECtrometer instruments from the late seventies. While COSPEC measurements continue today, they have been largely superseded by compact grating spectrometers, which were first introduced soon after the start of the 21st Century. Since 2006, a new approach to measuring fluxes has appeared, that of quantitative imaging of the SO2 slant column amount in a volcanic plume. Quantitative imaging of volcanic plumes has created new opportunities and challenges, and in April 2013 an ESF-funded MeMoVolC workshop was held, with the objectives of bringing together the main research groups, create a vibrant, interconnected, community, and examine the current state of the art of this new research frontier. This special issue of sixteen papers within the Journal of Volcanology and Geothermal Research is the direct result of the discussions, intercomparisons and results reported in that workshop. The papers report on the volcanological objectives of the plume imaging community, the state of the art of the technology used, intercomparisons, validations, novel methods and results from field applications. Quantitative plume imaging of volcanic plumes is achieved by using both infrared and ultraviolet wavelengths, with each wavelength offering a different trade-off of strengths and weaknesses, and the papers in this issue reflect this wavelength flexibility. Gas compositions can also be imaged, and this approach offers much promise in the quantification of chemical processing within plumes. One of the key advantages of the plume imaging approach is that we can achieve

    Full Text Available In 1989 the first bases of what is now a strong and consolidated Spanish-Italian scientific relationship in Seismology and in Volcano-Seismology were established. The first stage took place at the University of Catania, in the former Department of Earth Sciences, placed in the old Science Faculty, when a pre-doctoral student from the University of Granada, Cartuja Observatory (now called Andalusian Institute of Geophysics, arrived to complete his formation in seismology. During this stage, in addition to the training process, new contacts with researchers and mainly with pre-doctoral students of the former International Institute of Volcanology of the Italian National Research Council (IIV-CNR were stablished. These contacts have endured, grown and created a strong international scientific network with consolidated and credible research production. In a short time new working groups were integrated such as the Osservatorio Vesuviano in Naples or the Department of Physics of the University of Salerno from the Italian side, and the Department of Applied Physics of the University of Almería or the Volcanology Department of the Spanish Research Council (CSIC in Spain. At the present this non-official (but very active network comprises many Italian Research Centers belonging to the National Institute of Geophysics and Volcanology (INGV such as Catania, Naples, Rome, Palermo, Pisa or Bologna; Italian Universities as Salerno, Naples, L’Aquila or Calabrian, several Spanish Universities such as Granada, Almería, Jaen, Complutense, Cádiz or La Laguna, but also from other countries such as USA, Russia, Ireland, Portugal, México, Argentina, Germany, France, Norway or UK among others. This collaboration includes a continuous pre-doctoral students training protocols in which the exchange of fellows among the different institutions is fluent. [...

  18. Volcanic Ash -Aircraft Encounter Damages: in Volcanological Point of View

    Science.gov (United States)

    Aydar, Erkan; Aladaǧ, Çaǧdaş Hakan; Menteş, Turhan

    2017-04-01

    The jet era or age began at 1930 and 40's in aviation sector, with the production of first jet engine for the aircrafts. Since 1950's, the commercial aviation with regular flights were established. Civil aviation and air-transport drastically increased due to intensive demand, and declared at least 10 fold since 1970 by IATA report. Parallelly to technological and economical developpement, the commercial jets became more comfortable, secure and rapid, bringing the world smaller, the countries closer. On the other hand, according to Global Volcanism Program Catalogues of Smithsonian Institute, about 1,500 volcanoes have erupted in the Holocene, 550 of them have had historical eruptions and considered as active. Besides an average of 55-60 volcanoes erupt each year, and about 8-10 of these eruptions produce ash clouds that reach aircraft flight altitudes (Salinas and Watt, 2004). Volcanic ash can be expected to be in air routes at altitudes greater than 9 km (30,000 ft) for roughly 20 days per year worldwide (Miller &Casadeval, 2000). A precious compilation of incidents due to encounters of aircrafts with volcanic ash clouds covering the years between 1953 and 2009 was used in this work (Guffanti et al., 2010-USGS Report) with an additional information on Eyfjallajökull-2010 eruption. According to this compilation,129 incidents happened within the concerned time interval. The damages, in general, fall in second and third class of Severity index, indicating the damages are limited on airframe of the planes, or some abrasions in jet engine, windblast etc.. We focused on fourth class of severity index involving the damages on jet engine of aircraft (engine fail) due to ingestion of volcanic ash and investigate eruption style and caused damage relationships. During the eruptive sequences of Mts Saint Helen (USA), Galunggung (Indonesia, 2 incidents), Redoubt (USA), Pinatubo (Philipinnes), Unzen (Japan), Manam (Papua New Guinea), Soufriere Hills (Lesser Antilles), Chaiten (Chilie), Eyfjallajökull (Iceland). The common point of all those eruptions is that all eruption clouds had the external water input. This input was as phreatomagmatic style eruption, ice plugged-vent clearing-vulcanian, heavy rain fall on eruption cloud or on eruptive vent, typhoon, ice grain in eruptive cloud, etc. We will show water input, case by case, to those eruptions belonging to severity index 4. Besides, we will also present other damages created by volcanic ash-aircraft encounters basing on their eruption styles as a result of advanced statistical methods.

  19. Topography and Volcanology of the Huangtsuishan Volcano Subgroup, Northern Taiwan

    Directory of Open Access Journals (Sweden)

    Yu-Ming Lai

    2010-01-01

    Full Text Available Combining the shaded relief topography model and the slope map from the Digital Terrain Model (DTM images, toporaphical map, field occurrences and petrography, the volcanic sequences of the Huangtsuishan Volcano Subgroup (HVS can be constructed. Two types of volcanic centers can be identified in this area. One is the Tachienhou volcanic dome, which may be located in the center of an older caldera. The other is the Huangtsui composite volcano, which is composed of interbedding lava flows and pyroclastic deposits with a volcanic crater named the Huangtsui pond at the summit. Eight lava plateaus radiated from Mts. Huangtsui and Tachienhou to the north and the east can be distinguished based on the DTM images. The volcanic deposits are comprised of four lithofacies, the lava flows, pyroclastic breccias, tuffs and lahars on the base of field occurrences. At least thirteen layers of lava flow, named the H1 to H13 can be recognized in the HVS and can be reconstructed and categorized into four stages. An old and large volcano erupted lava flows to form the products of stages one and two, then collapsed to form a caldera with a dome for the third stage. The latest stage of lava flow was poured out from the Huangtsui volcano, which formed a crater at the summit.

    The study of volcanic hazards leads inevitably to questions of how past cultures have lived in volcanically active regions of the world. Here we summarize linkages between volcanological, archaeological and anthropological studies of historic and prehistoric volcanic eruptions, with the goal of evaluating the impact of past eruptions on human populations to better prepare for future events. We use examples from papers collected in this volume to illustrate ways in which volcanological studies aid archaeological investigations by providing basic stratigraphic markers and information about the nature and timing of specific volcanic events. We then turn to archaeological perspectives, which provide physical evidence of the direct impacts of volcanic eruptions, such as site abandonment and human migration, as well as indirect impacts on local cultures as reflected in human artifacts. Finally we review anthropological studies of societal responses to past and recent volcanic eruptions. We pay particular attention to both the psychological impact of catastrophic events and records of these impacts encoded within oral traditions. Taken together these studies record drastic short-term eruption impacts but adaptation to volcanic activity over the longer term, largely through strategies of adaptive land use.

    The Kurile-Kamchatka-Alaska portion of the Pacific Rim of Fire spans for nearly 5400 km. It includes more than 80 active volcanoes and averages 4-6 eruptions per year. Resulting ash clouds travel for hundreds to thousands of kilometers defying political borders. To mitigate volcano hazard to aviation and local communities, the Alaska Volcano Observatory (AVO) and the Institute of Volcanology and Seismology (IVS), in partnership with the Kamchatkan Branch of the Geophysical Survey of the Russian Academy of Sciences (KBGS), have established a collaborative program with three integrated components: (1) volcano monitoring with rapid information exchange, (2) cooperation in research projects at active volcanoes, and (3) volcanological field schools for students and young scientists. Cooperation in volcano monitoring includes dissemination of daily information on the state of volcanic activity in neighboring regions, satellite and visual data exchange, as well as sharing expertise and technologies between AVO and the Kamchatkan Volcanic Eruption Response Team (KVERT) and Sakhalin Volcanic Eruption Response Team (SVERT). Collaboration in scientific research is best illustrated by involvement of AVO, IVS, and KBGS faculty and graduate students in mutual international studies. One of the most recent examples is the NSF-funded Partnerships for International Research and Education (PIRE)-Kamchatka project focusing on multi-disciplinary study of Bezymianny volcano in Kamchatka. This international project is one of many that have been initiated as a direct result of a bi-annual series of meetings known as Japan-Kamchatka-Alaska Subduction Processes (JKASP) workshops that we organize together with colleagues from Hokkaido University, Japan. The most recent JKASP meeting was held in August 2011 in Petropavlovsk-Kamchatsky and brought together more than 130 scientists and students from Russia, Japan, and the United States.

    Full Text Available In this column we describe a hands-on data collection lab for an introductory statistics course. The exercise elicits issues of normality, sampling, and sample mean comparisons. Based on volcanology models of tephra dispersion, this lab leads students to question the accuracy of some assumptions made in the model, particularly regarding the normality of the dispersal of tephra of identical size in a given atmospheric layer.

    Data from direct measurements of stratospheric optical depth, Greenland ice-core acidity, and volcanological studies are compared, and it is shown that relatively small but sulfur-rich volcanic eruptions can have atmospheric effects equal to or even greater than much larger sulfur-poor eruptions. These small eruptions are probably the most frequent cause of increased stratospheric aerosols. The possible sources of the excess sulfur released in these eruptions are discussed.

    When teaching at a non-English language university, we often argue that because English is the international language, students need to become familiar with English terms, even if the bulk of the class is in the native language. However, to make the meaning of the terms clear, a translation into the native language is always useful. Correct translation of terminology is even more crucial for emergency managers and decision makers who can be confronted with a confusing and inconsistently applied mix of terminology. Thus, it is imperative to have a translation that appropriately converts the meaning of a term, while being grammatically and lexicologically correct, before the need for use. If terms are not consistently defined across all languages following industry standards and norms, what one person believes to be a dog, to another is a cat. However, definitions and translations of English scientific and technical terms are not always available, and language is constantly evolving. We live and work in an international world where English is the common language of multi-cultural exchange. As a result, while finding the correct translation can be difficult because we are too used to the English language terms, translated equivalents that are available may not have been through the peer review process. We have explored this issue by discussing grammatically and lexicologically correct French, German, Icelandic, Indonesian, Italian, Portuguese, Russian, Spanish, and Japanese versions for terms involved in communicating effusive eruption intensity.

    The Black Swan district, 70 km north east of Kalgoorlie in the Archaean Yilgarn Craton of Western Australia, hosts massive and disseminated nickel sulfide orebodies associated with komatiites. The host rocks and ores preserve some remarkable primary igneous features, which provide important clues as to the origin of komatiite-hosted nickel ores. The series of papers that follow report an extremely detailed study of the petrology, volcanology and geochemistry of these unusually well-preserved orebodies and their host rocks.

    implications regarding the magma reservoir location and arrest levels of ascending magma), iv) hydrothermal facies distribution (mainly at depths affected by thermo-metamorphism), v) elastic parameters (mainly Vp and Vp/Vs) of cored rocks measured in laboratory; vi) surface fluid emissions (as the surface expression of faults and fractures), vii) hydrogeology (location of thermal aquifers and general water circulation), and viii) seismology (location of main geophysical discontinuity and of seismic wave anomaly, seismogenetic and attenuation volumes). Our model evidences the lack of information from deep layers in the eastern caldera sector, i.e., the Bagnoli Plain and in the Pozzuoli Gulf. Investigations of these sites would add important information to our present knowledge of the geothermal system, as well as of the caldera structure and related magma-system behavior. Furthermore, the Bagnoli Plain is one of the largest Italian dismantled industrial areas, affected by metal contamination and undergoing to reclamation. It is, presently, a sparsely inhabited zone within the city of Naples, which therefore allows deep volcanological and geothermal investigations as well as requalification in terms of clean and renewable resource use, in contrast with the other peripherals areas where the high-population density poses strong limitations to the research and to the possibility to plan new rational use of the land and of its resources.
