PaleoSeismology Laboratory The PaleoSeismology Laboratory is a specialized research unit devoted to reconstructing prehistoric earthquake activity through geological, geochemical, and geochronological investigations. The laboratory integrates field geology, stratigraphy, geomorphology, and laboratory-based dating to inform seismic hazard assessments used by agencies and institutions worldwide. Its work informs policy and planning by linking long-term rupture histories to urban, regional, and continental seismic risk across diverse tectonic settings.

Key Findings and Contributions

The laboratory has quantified paleoearthquake recurrence intervals, slip rates, and multi-segment rupture behaviors that have revised hazard models for regions including the San Andreas Fault, Cascadia Subduction Zone, Japan Trench, Nankai Trough, Sumatra Fault, Haiyuan Fault, Haiyang Fault Complex, North Anatolian Fault, East Anatolian Fault, Zagros Fold and Thrust Belt, Alpine Fault, Alps, Himalaya, Kunlun Fault, Denali Fault, Queen Charlotte Fault, Meylan Fault Complex, New Madrid Seismic Zone, Gujarat region, Loma Prieta, Sichuan Basin, Kermadec Trench, Chile Trench, Aleutian Subduction Zone, Puerto Rico Trench, Turkey, Iran, Greece, Italy, New Zealand, Iceland Rift Zone. Contributions have influenced reports by USGS National Seismic Hazard Model, Intergovernmental Panel on Climate Change assessments (tectonic impacts), World Bank seismic risk projects, and building codes in jurisdictions such as California Building Standards Commission and Eurocode-implementing authorities.

Collaborations and Training

The laboratory runs joint programs with universities, government surveys, international agencies, and industry partners, providing training in trenching, paleoseismic interpretation, and geochronology for students and professionals from United Nations Development Programme, USAID, European Union Civil Protection Mechanism, Asian Development Bank, Inter-American Development Bank, Red Cross, FEMA, California Office of Emergency Services, Japan Meteorological Agency, Taiwan Earthquake Research Center, Korea Meteorological Administration, Mexican Seismological Service, Instituto Geofísico del Perú, Geoscience Australia, GeoScience Ireland, U.S. Department of Energy, and private consultancies such as AECOM and Arup.

Notable Case Studies and Applications

Case studies include paleoseismic reconstructions of the 1700 Cascadia earthquake linked to oral histories and tsunami deposits correlated with studies by Vancouver Island, Tofino, Port Alberni, Olympic Peninsula, and Willapa Bay investigations; trenching studies along the Hayward Fault that affected Oakland and San Francisco Bay Area planning; Holocene slip-rate estimation on the Alpine Fault informing Christchurch resilience; and turbidite-based rupture histories in the Japan Trench that fed into tsunami hazard scenarios for Sendai and Fukushima. Other applications include paleoliquefaction evidence used after the 1944 Tonankai earthquake analog studies, sedimentary records relevant to the 1755 Lisbon earthquake debate, and sediment core correlations applied in Sunda Trench tsunami studies for Aceh and Sumatra response planning.
