********************************************************************* From: Simon Carn <scarn@xxxxxxxx> ********************************************************************* Dear all, As the abstract deadline approaches, we would like to draw your attention to the following special session at the AGU Fall Meeting. Although the focus is on the eruption of Chaitén, we will gladly consider abstracts on any aspect of recent volcanism in the Chilean southern volcanic zone (SVZ). V17: The First Historical Eruption of Chaitén Volcano, Southern Chile Sponsor: Volcanology, Geochemistry, and Petrology Description: On May 2, 2008 Chaitén volcano (southern volcanic zone, Chile) erupted for the first time in many thousands of years, marking the first monitored eruption of rhyolite magma from a caldera and the first VEI 5 eruption of this century. Between May 2 and May 8, the volcano produced a series of ash plumes that rose to 10-20 km altitude, depositing pumiceous tephra and ash downwind and extending east to the Atlantic coast of Argentina. Following the initial plumes, simultaneous eruption of lower-level ash plumes and a large lava dome took place within the volcano's 4 km-diameter caldera. As of mid-June activity at Chaitén is continuing. The eruption has been monitored by the Chilean National Service of Geology and Mining (SERNAGEOMIN), supplemented by a response team from the USGS Volcano Disaster Assistance Program (VDAP). Contributions on satellite remote sensing, ground-based monitoring, petrological studies, the geologic context and impacts of this unusual eruption are solicited. Papers describing studies of analogous volcanic systems elsewhere are also welcome.
