********************************************************* From: David J Schneider <djschneider@xxxxxxxx> ********************************************************* AGU Session A53: The 2008 Eruptions of Okmok and Kasatochi Volcanoes, Alaska We would like to call your attention to a newly added session at the AGU Fall Meeting entitled: The 2008 Eruptions of Okmok and Kasatochi Volcanoes, Alaska Sponsor: Atmospheric Sciences (Session A53) CoSponsors: Geodesy Seismology Volcanology, Geochemistry, and Petrology Description: During the summer of 2008 two large explosive volcanic eruptions occurred in the Aleutian Volcanic Arc at Okmok Caldera and Kasatochi Volcano. On July 12, 2008 Okmok Caldera in the central Aleutian Arc erupted with notably short seismic precursors. Continuing eruptive activity has been characterized by protracted periods of explosive activity accompanied by volcanic tremor and large ground deformation. On August 7, 2008 Kasatochi Volcano began eruption following a strong sequence of earthquake activity and volcanic tremor. These eruptions were highly explosive producing ash plumes that reached altitudes of 10 to 20 km. Volcanic clouds of ash, gas, and aerosols from these eruptions were transported across the Northern Hemisphere and caused disruptions to airline traffic over North America. These are the first two eruptions in the Aleutian arc that have produced such widely distributed atmospheric plumes since 1992, and were tracked by a variety of satellite sensors. Contributions covering all aspects of these two large explosive eruptions are welcome including satellite and ground based remote sensing, ground based monitoring, petrologic studies, as well as the geologic context, hazards and impacts Abstract Deadline is September 10 at 2359 UTC and need to be submitted online at: http://submissions3.agu.org/submission/entrance.asp Feel free to contact myself or one of the CoConveners if you have any questions about this session. We look forward to receiving your abstract on these very interesting eruptions!
