[unav_all] REMINDER - Subduction Zone Observatory SIG Meeting at AGU

*Subduction Zone Observatory Special Interest Group Discussion at Fall 
AGU Meeting
*Thursday, December 18
3:30-5:00PM
City Club of San Francisco, Salon Room, 9th Floor
155 Sansome St (~0.7 mile walk from Moscone South)

Discussion Leaders: Geoff Abers, Doug Wiens
The SIG will be framed with short (<10 min each) presentations on the 
outstanding science questions across several subduction zone related topics.
Speakers: Jeff Freymueller (faulting and deformation), Katie Kelley 
(magmatic processes), Magali Billen (geodynamics), John Vidale (hazards)

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.
