This multidisciplinary workshop will explore potential joint efforts between MARGINS and EarthScope/GeoSwath in the Cascadia subduction zone (a SubFac Allied Site of MARGINS) and the Walker Lane/ Salton Trough extensional corridor. Geophysical measurements are currently ongoing in the area by the EarthScope Transportable and Flexible Arrays and by the Plate Boundary Observatory, and all are relevant to MARGINS initiative goals. The workshop will last 1 day just prior to the March 2007 EarthScope National Meeting in Monterey, CA.
 
The EarthScope facility provides unprecedented tools for imaging the strain and structure of North America. To date, funded EarthScope projects have been largely geophysical, with relatively little integrated studies, because of the nature of the facility, and have been only on shore. By contrast, the MARGINS Program provides a structure and intellectual framework for integrative studies across active continental margins. MARGINS limits field efforts to Focus Sites, which except for the Salton Trough do not overlap with EarthScope targets. As MARGINS reaches the latter part of its decadal cycle, it becomes increasingly apparent that some studies may not be possible within Focus Sites, but are critical to the success of the program.
 
This workshop aims to document fruitful problems of mutual interest in Cascadia and the Walker Lane / Salton Trough areas, and bring together geoscientists interested in multidisciplinary research in these two areas, to discuss future plans.
