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.
