Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Combining GPS and Remotely Sensed Data to Characterize Time-Varying Crustal Motion

Development of more physically realistic models of interseismic crustal strain and stressing rates, postseismic effects over multiple time scales, transient deformation, and lithospheric rheology are examples of research applications requiring measurements of Earth surface motion at high spatiotemporal resolution. To address this need, the Southern California Earthquake Center (SCEC) has initiated a 5-year project to create a Southern California community geodetic model (CGM) that will leverage the complementary strengths of temporally dense GPS and spatially dense interferometric synthetic aperture radar (InSAR) data. A workshop was held May 30 - 31, 2013 that brought together experts in the analysis of geodetic data as well as potential users of the CGM. Outcomes of the workshop were further development of the CGM project plan, including required features, overall approach, and progression of tasks; identification of active participants; and to strategizing to coordinate work.
