SSA 2026 Session - Southern California Seismicity: Past, Present, and Future

[Tepp, Gabrielle M.]

Dear colleagues,

We invite you to submit to our session at the Seismological Society of America (SSA) annual meeting, April 14-18, 2026, in Pasadena, CA. The abstract deadline is next week - January 13: https://meetings.seismosoc.org/submit/ We encourage presentations related to any aspect of Southern California earthquakes and seismicity.

Southern California Seismicity: Past, Present, and Future

Seismic investigation of Southern California began around a century ago to better understand the processes and hazards associated with several major fault zones, such as the San Andreas, and numerous other minor and subsidiary faults. The long history of seismic monitoring in the region – with regional/teleseismic instrumental monitoring dating back to ~1900, the local seismic network established in the 1920s, and the official earthquake catalog starting in 1932 – has allowed for many ground-breaking studies on earthquakes and their effects. In this session, we welcome all presentations related to Southern California seismicity, from past events preserved in the geologic record to data analysis of recent events to modeling of what we may expect in the future. In order to fully understand both short-term seismic and long-term tectonic processes, we need contributions from seismology, geology, and geodesy as well as from observational, experimental, and theoretical work. We hope this session can help spur discussion and collaboration for furthering our understanding of Southern California seismicity and related hazards.

We look forward to welcoming you to Pasadena and SoCal this spring!
