********************* Roberto Scandone scandone@xxxxxxxxxxxxxxx ********************* Dear colleagues, We would like to draw your attention to our session on Calderas II: Calderas and caldera forming eruptions to be held during the IUGG Perugia General Assembly, Perugia, Italy, 2-13 July, 2007. For additional information on the IUGG general assembly 2007 visit http://www.iugg2007perugia.it/ The abstract deadline is 31 January, 2007. Best regards, Roberto Scandone A description of the session is provided below. VS007: Calderas II: Calderas and caldera forming eruptions Sponsoring Association: IAVCEI Calderas involve the rapid eruption of magma from crustal reservoirs that vary in size and shape in different tectonic environments. Some caldera-forming eruptions have been far larger than any in the historical record and may have had large impacts on earth climate. In contrast, other large volcanoes have been active for hundred thousands of years without caldera-forming eruptions. Much recent volcanological research is aimed at understanding the conditions favoring the occurrence of large caldera-forming eruptions, how the magma reservoir develops in time, and how the resulting caldera is related to the style of the causative eruption. Lacking direct observation of unrest that preceded large caldera- forming events, we are dependent on the geologic record of precursory eruptive activity. Will we be able such data to forecast large caldera-forming eruptions in the future? This session focuses on the diverse methods, including field observations, petrologic and geochronologic studies, geophysical monitoring, and physical and numerical modeling, that can help understand the conditions leading to a caldera-forming eruption, its temporal evolution, and the form and shape of the resulting caldera and associated subvolcanic magma reservoir.
