APPLICATION DUE: July 10, 2025
Attendance is limited to 40 in-person participants. The accepted participant list will be finalized by July 15, 2025. 

Overview

Developing Community Earth Models (CEMs) is a central initiative of the Statewide California Earthquake Center (SCEC). With the recent expansion of SCEC’s statewide scope, there is an urgent need to broaden the geographical coverage of these models. Among the key components of the CEMs are the Geological Framework Model (GFM) and the Community Thermal Model (CTM), which serve as foundational elements for other models such as the Community Rheology Model (CRM). These models provide essential context for interpreting velocity, geodetic, and stress data.

SCEC’s success will, in part, be measured by its ability to extend these models and other CEM components into northern California. This joint GFM and CTM workshop aims to identify critical datasets and mobilize the community of volunteers dedicated to updating and expanding these models to encompass the entire state of California.

The SCEC GFM/CTM workshop will be held at the University of California, Davis, and will span a day and a half of presentations, discussions, and breakout sessions aimed at advancing Community Earth Models across California. Day 1 will feature model reviews, short contributed talks, and focused discussions on northern California geology and CTM methods. Day 2 will include a recap, an invited overview of the Community Fault Model, and breakout sessions to define next steps for the GFM and CTM.

We welcome applications from individuals across all disciplines relevant to the development of a geological framework or rheological model of California. We especially encourage participation from students, postdocs, and early career scientists. In-person attendance is limited to 40 participants who will be selected on the basis of their statement of interest and the potential of their contributions to the community rheology and geological framework development efforts. Limited travel support will be available. Applicants not accepted will receive a link to join the workshop via Zoom.

SCEC Community Earth Models (CEM) and Datasets

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.

SCEC Activities Code of Conduct

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.

SCEC Meetings and Workshops

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.
