<b>Subduction Zone Observatory Special Interest Group Discussion at
Fall AGU Meeting<br>
</b>Thursday, December 18<br>
3:30-5:00PM<br>
City Club of San Francisco, Salon Room, 9th Floor<br>
155 Sansome St (~0.7 mile walk from Moscone South)<br>
<br>
Discussion Leaders: Geoff Abers, Doug Wiens<br>
The SIG will be framed with short (<10 min each) presentations on
the outstanding science questions across several subduction zone
related topics.<br>
Speakers: Jeff Freymueller (faulting and deformation), Katie Kelley
(magmatic processes), Magali Billen (geodynamics), John Vidale
(hazards)
<br>
<br>
The discussion will focus on the creation of a Subduction Zone
Observatory (SZO) to enable research on all facets of subduction
zone processes and facilitate a systems approach to a complex,
inter-linked set of processes active at subduction zones including
the incoming and overriding plates. A SZO would improve our
understanding of the physical processes involved in a variety of
natural hazards including earthquakes, tsunamis, volcanic eruptions,
and landslides. The observations would also be relevant to a number
of grand challenges in Earth science, including fluid flux through
the crust and mantle, geochemical processes in arcs, injection of
water into the mantle, and deformation responses to megathrust
earthquakes on times scales from seconds to millions of years and
spatial scales from millimeters to thousands of kilometers. Our
goals at this meeting are to discuss specific objectives for an SZO,
identify potential international collaborators, target other
geoscience communities with interests in SZO science, and to make
progress towards a workshop in Fall 2015 to articulate the major
science objectives and required facilities for a SZO.
