Join us for the 2026 COSMOS Technical Session and Annual Meeting, which will be held at the Degenkolb Office Building, 601 12th Street, Second Floor, Oakland, California, 94607 from February 18-19, 2026. Yes, this is a TWO DAY, hybrid event! Remote/virtual access will be available for participants who cannot attend in person.

COSMOS promotes the use of instrumentation and simulations for ground-motion, geotechnical, and structural response analyses to foster community resiliency by promoting international guidelines, state-of-the-art processes, and global collaboration. Aligned with our mission, the first day of this year’s program includes two related workshops on site characterization and ground motion simulations and include a roundtable discussion led by the Early Career and Student Committee. On the second day, we have relevant presentations on COSMOS/CGS/USGS joint activities (including an update on the NGA-West3 Database), theme sessions related to community velocity modeling and recorded ground motion database development efforts from around the world, and engineering practice-oriented sessions focusing on the use of time series in engineering analyses and upcoming building code updates. The detailed program is presented below. As always, there will be plenty of opportunities for open discussion and dialogue with presenters and panelists throughout the program.

We invite you to help COSMOS bring together the global earthquake community. Our vision is to elevate the standard of practice for seismic hazard assessment and risk reduction through stimulating discussions and information exchange. Please join us this February as we work toward realizing our vision. Hope to see you there!
