CGS Information Warehouse: Tsunami Inundation Maps

Produced collectively by tsunami modelers, geologic hazard mapping specialists, and emergency planning scientists from the University of Southern California (USC) Tsunami Research Center, CGS, and Cal OES. The Tsunami Inundation Maps for Emergency Planning cover all low-lying, populated areas along the State’s coastline. Coordinated by Cal OES, these inudation maps are developed for at risk areas to tsunamis in California and represent a combination of the maximum considered tsunamis for each area.
