7th Kenji Ishihara Colloquium Series on Earthquake Engineering | Day 1
Fault Displacement
Thursday, August 21st, 2025, 8:30am-5pm
University of California, San Diego
Franklin Antonio Hall 1301
The first day of the 7th Kenji Ishihara Colloquium Series on Earthquake Engineering, cohosted with EERI UCSD, will spotlight critical advances in understanding and mitigating surface fault rupture hazards. The program features expert presentations on infrastructure design challenges near active faults, probabilistic fault displacement hazard assessments, and new seismotectonic models for the San Diego region. Notable speakers in the field will offer unique perspectives from engineering practice, international nuclear safety, and academic research.

June 2025 Webinar
ISSUES ASSOCIATED WITH SIMPLIFIED PROCEDURES TO EVALUATE LIQUEFACTION TRIGGERING AND CONSEQUENCES
Wednesday, June 18th, 2025
10:30am-12pm PDT
Virtual Event
This free webinar, presented by the San Diego Regional Chapter, will address some issues associated with simplified procedures to evaluate liquefaction triggering and consequences. These issues include earthquake source type, ground motion shape, loading duration related to liquefaction triggering, and other limitations. New approaches for the calculation of CRR, CSR (subduction environment) and MSF will also be presented. In addition, discussion will include the mismatch between surface evidence and the likelihood of liquefaction that may reach unacceptable values in subduction environments. Case histories presented by the three speakers will be the basis for the discussion in the webinar. Martin Hudson will also open the webinar with an eulogy for Marshall Lew.
