USC Tsunami Research Center

The TRC is actively involved with all aspects of tsunami research; inundation field surveys, numerical and analytical modeling, and hazard assessment, mitigation and planning.
The TRC has developed the tsunami inundation maps for California and the tsunami code MOST, now used by NOAA. MOST is the only validated code used in the US for tsunami hazard mapping with detailed inundation predictions. TRC faculty and students have surveyed all except one of the "modern" tsunamis since 1992, and have been working on mega-tsunami surveys for the 1946 Aleutian and 1956 Amorgos, Greece events. The TRC is a unit of the Department of Civil Engineering.

We acknowledge the support of the National Science Foundation (NSF), the Federal Emergency Management Agency (FEMA), the Governor's office of Emergency Services (OES) and the Earthquake Engineering Research Institute (EERI) that have made our field and modeling work possible. This site started in 1995 with the generous encouragement and support of NSF's Dr. Cliff Astill and is dedicated to showcasing the impact of recent tsunamis.

Please use our interactive map above to learn about past tsunamis by dragging the blue square on the left map and viewing details on the right. Click on the pulsating circles on the right detail map to learn about a specific location.
