Dear Colleagues,
We would like to encourage you to submit abstracts to the following session at the 2013 Fall Meeting of the American Geophysical Union (AGU) this coming December 9-13. All abstract submissions must be received by 6 August 2013 at 23:59ET/3:59+1 GMT.
V047. Volcanism in California: Geophysics, Geology, and Geochemistry of the young and the restless
The USGS established California Volcano Observatory (CalVO) in February 2012 to improve coordination with emergency response agencies and create new opportunities for volcanic hazard awareness and collaborative research. CalVO has broad responsibility for all of California’s potentially threatening volcanoes, most notably Mount Shasta, Medicine Lake, Clear Lake Volcanic Field, and Lassen Volcanic Center in the north; Long Valley Caldera and Mono-Inyo Craters in east-central California; and Salton Buttes, Coso Volcanic Field, and Ubehebe Craters in the southern part of the state.
California is geologically diverse, exhibiting a range of volcanism resulting from subduction, crustal thinning, and extensional rifting in the northern, central, and southern parts of the State, respectively. Volcanic eruptions occur in the State about as frequently as the largest San Andreas Fault Zone earthquakes-more than ten eruptions have occurred in the last 1,000 years, most recently at Lassen Volcanic Center (1666 C.E. and 1914-1917 C.E.) and Mono-Inyo Craters (c. 1700 C.E.). The Long Valley Caldera and Mono-Inyo Craters region underwent several episodes of heightened unrest over the last three decades, including intense swarms of VT earthquakes, rapid ground uplift, and dangerous CO2 emissions. Both Medicine Lake and Lassen are subsiding at the appreciable rate of 8-10 mm/year, and along with Clear Lake, sporadically experience LP earthquakes related to migration of magma or hydrothermal fluid. With the exception of Ubehebe Craters, all of California’s “watch list” volcanoes support vigorous hot springs, boiling mudpots, and/or fumarolic activity, and four are geothermal power producers.
This session is an opportunity to review current knowledge of California volcanism and identify future research directions at potentially threatening volcanoes. This session provides an opportunity to review the current state of knowledge at California and Nevada volcanoes and identify future research directions. We encourage geophysical, geological and geochemical studies contributions on topics including: volcanic history, magma sources and fluxes; current seismicity, deformation, and degassing; tectonic-magmatic interactions; multidisciplinary research; and volcanic hazard assessment and mitigation.
