Towards Statewide and 3-D Deformation Fields for California
Date: September 7, 2024 (9:30 am – 5:30 pm)
Location: Hilton Palm Springs, California
Workshop Organizers: Mike Floyd (MIT) , Katia Tymofyeyeva (NASA JPL)
Award: 24074
Do you use or generate geodetic data in your research? Are you interested in using or contributing to a curated set of deformation time series and velocities, showcasing your analysis and applications, or aiding a community effort to address inconsistencies in geodetic products? The SCEC Community Geodetic Model (CGM) is a long-term effort to integrate GNSS and InSAR data, from the modern satellite-based geodetic era, in a self-consistent, rigorous and open manner, to derive secular and time-dependent surface velocity and strain rate fields across California. We invite diverse expertise and users to contribute to and benefit from this effort as we extend the temporal and geographic range statewide.
This full-day pre-SCEC Annual Meeting workshop includes invited talks, breakout sessions, and discussions on geodetic product needs and challenges. We aim to identify key research issues, educate users, and address critical questions in the context of SCEC science goals.
We welcome current or potential users or contributors, and encourage early-career students, postdocs, researchers and faculty to participate in shaping the plans for the next generation of the SCEC Community Geodetic Model.

CEMs are collaborative platforms featuring community-contributed data, models, and tools for earthquake system analysis. They enable 3D visualization, data exploration, sharing, and integrated modeling. The current SCEC Community Geodetic Model (CGM) integrates high-precision GNSS and InSAR data for continuous, detailed ground movement monitoring in Southern California.

The Statewide California Earthquake Center (SCEC) fosters a diverse and inclusive community where everyone feels safe, productive, and welcome. We expect all participants in SCEC-supported events to uphold this commitment by adhering to the SCEC Activities Code of Conduct.
The SCEC Annual Meeting brings together 400-500 participants worldwide to share breakthroughs, assess progress, and chart a collaborative path for earthquake science. All of the Center activities are presented, analyzed, and woven into a set of priorities for SCEC to pursue in the future.
