Workshop on subduction, arc magmatic processes completes North Pacific meeting cycle



What was once a remote backwater in the study of Earth processes—subduction and associated volcanism and seismicity of the far north Pacific region—has become a locus of real-time observation. For example, the Alaska Volcano Observatory (AVO)—a collaborative project of the U.S. Geological Survey (USGS), the University of Alaska-Fairbanks (UAF), and the Alaska Division of Geological and Geophysical Surveys (ADGGS) at Anchorage and Fairbanks— now maintains real-time seismic monitoring networks on 25 active volcanoes, from Cook Inlet to Adak Island; conducts continuous operational satellite surveillance of Alaska and Kamchatka for volcanic hot spots and ash plumes; and is now implementing real-time continuous GPS networks. Also, the Kamchatkan Volcanic Eruption Response Team (KVERT) of the Institute for Volcanic Geology and Geochemistry and the Institute of Seismology (both in Petropavlovsk on the Kamchatka Peninsula) is similarly active in the Russian Far East.
