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.
