********************************************************************* IAVCEI General Assembly 2008 Caldera volcanism (session 2-i) From: Joan Marti <joan.marti@xxxxxxxxxxx> ********************************************************************* Dear colleagues, We would like to draw your attention to the following session on Caldera Volcanism that will be convened at the 2008 IAVCEI General Assembly in Reykjavik, Iceland. The abstract submission deadline is 1 April 2008, and information on the submission process and the Assembly can be found at http://www.jardvis.hi.is/page/i08-tinfo 2-i Caldera volcanism Conveners: J. Martí, Institute of Earth Sciences, Jaume Almera, CSIC, Barcelona, joan.marti@xxxxxxxxxxx A. Gudmundsson, Department of Structural Geology and Geodynamics, Geoscience Centre, University of Göttingen, Agust.Gudmundsson@xxxxxxxx goettingen.de G. De Natale, Osservatorio Vesuviano, INGV, Naples, pino@xxxxxxxxxx Collapse calderas have received considerable attention due to their link to Earth's ore deposits and geothermal energy resources, but also because of their impact on the environment (e.g. climate) and human beings. Volcanic hazards associated with collapse calderas differ markedly in spatial and temporal scales, and in their impact on the physical environment and on people. Possibly one of the most interesting volcanic hazards related to caldera-forming eruptions are the effects on global climate. Historical caldera-forming eruptions such as Tambora in 1815, Krakatau in 1883, and Pinatubo in 1991, although several orders of magnitude smaller than the largest prehistoric eruptions, appear to have had a significant impact on global climate, including visible atmospheric effects such as strange colours and halos around the sun and moon, vivid sunsets and sunrises, and anomalously cold weather. Moreover, calderas also provide key insights into the generation and evolution of large- volume silicic magma bodies. Furthermore, since caldera processes are the culmination of a complex interaction of geological processes occurring at regional and local scales, their study provides us with relevant information on lithospheric dynamics. This session will focus on: - Geological, petrological, geochemical, stratigraphical, structural and physical investigations of caldera-forming eruptions and caldera volcanism - Analogue and mathematical modelling of magma chamber and eruption processes related to caldera formation - Physicochemical properties of melts and magmas related to caldera volcanism - Multiparameter monitoring of restless calderas and implications from modelling - Global and climatic consequences of caldera-forming eruptions - Hazard assessment, risk mitigation and scenario planning at restless calderas ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
