2026 SCEC Stress Drop Workshop (Jan 20, 2026) REGISTER NOW!

[Abercrombie, Rachel]

Dear colleagues,

We invite you to the 2026 SCEC Community Stress Drop Workshop to be held online via Zoom on January 20th, 2026 9:00am - 3:30pm Pacific Time.  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.  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, but welcome those who simply want to listen and learn.

Please see more details and register here for your personal zoom link https://www.scec.org/events/2026-community-stress-drop-validation-workshop. While we always welcome everyone to attend, we encourage you to register by January 16.

We will hold the workshop in three sessions, please join for all or just what you're interested in! As always, we welcome participation and listening from all and we will have plenty of time for participant discussion and contributions.

Times below all Pacific

Session I (9am - 10:45am) Introduction, and ongoing work. We will hear a few invited talks on ongoing work, and then have time for contributed slides and discussion from the whole community on current progress. We are especially interested in how methods have evolved recently given feedback from the first stage of the Community Project.

Session II (11:00am - 12:30pm) New datasets. Presentations from community members on new empirical datasets and regions, with a discussion and perhaps a vote on what data to choose.

Session III (1:30pm - 3:00pm) Synthetic data and looking forward. We will hear about previous synthetic data analysis for earthquake stress drop or source parameters, and then a discussion of several stochastic and other simplistic datasets we will use for the Community Project. We will discuss future SCEC, NSF and international proposals.

Special Session: (3pm - 3:30pm). A review of the morning’s discussion for our global participants who could not make the earlier times (or anyone who was busy!).

*Note that the afternoon schedule and topics may change slightly depending on participation!
