We are excited to announce an in-person SCEC Community Stress Drop Workshop to be held on August 20, 2026 at the USGS Moffett Field, Mountain View, CA. The Community Stress Drop Validation Study aims to understand and reduce uncertainties in estimated spectral stress drop and related source parameters, strengthening their use in empirical ground motion models and earthquake source representations in simulations. The aim of this in-person workshop is to develop the design for the planned synthetic tests and begin analysis of the first synthetic data, together with selection of the optimal Bay Area empirical dataset. We will also further discuss future directions and leadership for additional thrusts of the proposed TAG, including efforts on seismic moment and magnitude, as well as modeling site attenuation and amplification.
|
To evaluate how effectively different methods can separate source, site, and path effects, identifying the effects of heterogeneity in each part, will require multiple, carefully designed synthetic experiments. For this workshop, we will distribute a small dataset of simple synthetic earthquake Fourier amplitude spectra for a community-scale test. All workshop attendees, and any additional interested participants, are invited (and encouraged!) to take part in this initial community effort. These results will be discussed at the workshop, where we will also develop plans for the next, larger phase of the synthetic experiment.
|
|
The format will be primarily discussion based with time for networking, breakout groups and a poster session, and will run the whole day, approximately 9am - 5pm. SCEC is offering limited travel support for both local and long-distance participants, which may include lodging, travel and meal expenses. Please apply by Thursday, July 16 to attend the workshop; please complete the travel support section carefully to be fully considered for support.

Who Should Apply. We welcome applications from, and aim to achieve a balanced representation of, participants from observational seismologists and engineers, rupture modelers, and lab-based geophysicists. We welcome those who have or want to analyze stress drop, and those who want to learn more about it, or are interested in supporting or leadership roles in the project.
|
We also seek a balance across career stages, including graduate students, early-career researchers, and established investigators, to promote cross-generational exchange and collaboration. An in-person poster session will enable participants to showcase and discuss ongoing work on stress drop and related topics. Participants are encouraged to bring a new or previously presented poster on any relevant theme.
