2008 Annual Meeting: Salton Trough Seismic Project Workshop

Conveners: John Hole, Joann Stock, and Gary Fuis
Date: September 10-11, 2008
Location: Plaza Ballroom AB, Hilton Palm Springs Resort

NSF (Margins/Earthscope) and the USGS are funding an active-source seismic study of the Salton Trough, including the Mexicali, Imperial, and Coachella Valleys, to take place in January 2010. This 1.5 day SCEC workshop is designed to promote synergy between this study and other related research efforts, and to inform relevant land management agencies of the plans and goals of the project. We will discuss the survey plans, other piggyback and complementary studies that have already been proposed, and the general tectonic background of the region. The goal of this workshop is threefold: 1) to update interested researchers and land managers on the current state of plans for this major study; 2) to seek community suggestions for details of instrument placement, timing of shots, etc. in the context of possible piggyback studies; and 3) to encourage discussion of other types of complementary projects in tectonics, geology, seismology, engineering seismology, etc. that may be suitable for proposal submission to SCEC or other funding sources in 2008.

The relationship of this project to the mitigation of earthquake hazards in the Salton Trough is further discussed on a separate page.
