******************************************************** From: Barry Voight <voight@xxxxxxxxxxx> ******************************************************** Dear Volcanophiles, We would like to draw your attention to volcanology session V11 at this year's Fall AGU, which addresses imaging and tomography at arc volcanoes. Contributions are invited on geophysical studies of arc islands, and related sea or land investigations, including land and/or sea operations, tomography, reflection profiling, magma generation and storage in arc settings, streamer profiling, inferences of GPS and strain data on magma storage/transport systems, petrology studies bearing on magma storage, and related studies. Please see the session description below and note the abstract submission deadline of 10th September. We hope to have an informative and lively session with plenty of discussion ! Best wishes, Barry Voight and co-convenors ---------------------------------------------------------------------------- V11: Volcano imaging experiments at Montserrat and other arc volcanoes Sponsor: Volcanology, Geochemistry, and Petrology CoSponsor: Seismology Conveners: B Voight [voight@xxxxxxxxxxx], Steve Sparks [Bristol], Eylon Shalev , D Hidayat [PSU] Session description: Since 1995 the eruption of the andesitic Soufrière Hills volcano (SHV), Montserrat, has been studied in unprecedented detail and the volcano has become an important natural laboratory for investigations of volcanic processes. Deep processes exert important controls on this eruption, but the structure of the island arc crust and upper mantle, and the magmatic system, are inadequately defined. The SEA CALIPSO project, implemented in 2008, was therefore devised to image the lithosphere and magma chamber at SHV using tomography and reflection seismology. Thus, geophysical investigations of arc volcanoes (e.g., Montserrat, Deception, Mount St Helens, Unzen, Stromboli) in the last few years have led to new information on the physical structure of the crust and upper mantle under and adjacent to the volcanoes, and on their magma storage and transport systems. Such investigations have been supplemented by studies of seismology, GPS and strain deformation, gravity, petrology, mineralogy, erupted lava budgets, and observational volcanology. These data are useful to develop models of volcanic processes, arc volcanism, arc crust evolution by igneous processes, and andesite magma genesis. We invite papers on geophysical studies of arc islands, and related sea or land investigations, including land and/or sea operations, active source tomography, Q and reflected ray tomography, passive source tomography, reflection profiling, magma generation and storage in arc settings, OBS data and modeling, streamer profiling of structure and stratigraphy of volcanic wedges in sea-floor sediments, implications of GPS and strain data on magma storage/transport systems, pluton xenoliths in relation to observed seismic velocities, petrology studies bearing on magma storage, focal mechanisms from dense seismic arrays.
