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!

Research Highlights

Mike Floyd: State of the Community Geodetic Model (more presentations)

The Community Geodetic Model (CGM) provides displacement time series and velocities of the Earth’s surface over southern California.

The Community Stress Drop Validation technical activity group is focused on resolving discrepancies in earthquake stress drop.

The Community Rheology Model (CRM) provides a three-dimensional description of the ductile rheology of southern California’s lithosphere.
