Summary

The Community Stress Drop Validation Study is a global community of researchers that always welcomes new members interested in reliable source parameter measurements. Our focus is understanding the physical controls and methodological reasons for similarity or differences in stress drops and other source characterization parameters, to enable more reliable use by the earthquake science community. Over the past four years, over 20 research groups have submitted stress drop estimates from the 2019 Ridgecrest Sequence common dataset, and many more have participated in analysis, workshops and community building. The results to date were recently published in a BSSA special issue on Improving Measurements of Earthquake Source Parameters. So far, we have demonstrated and quantified the uncertainties in methodological biases in stress drop estimates, and their possible magnitude and depth dependencies. Check here for more info and links to recent work and efforts!

The next step is for the community to investigate and test improved approaches and address the remaining unanswered questions, using a new empirical dataset and synthetic datasets. In this workshop, we will discuss ongoing work on new methods on both empirical and synthetic datasets, and discuss new data. We will also discuss future plans for an expanded community study.

Anyone who is interested in stress drops or source parameters, or their use and implication in other fields, is encouraged to attend! We welcome those from all research backgrounds at any stage of your career. As always, we will have multiple opportunities for discussion and participation.
