Produced collectively by tsunami modelers, geologic hazard mapping specialists, and emergency planning scientists from
CGS,
Cal OES, and the
Tsunami Research Center at the University of Southern California, the tsunami inundation maps for California cover most residentially and transient populated areas along the state’s coastline. Coordinated by Cal OES, these official maps are developed for all populated areas at risk to tsunamis in California and represent a combination of the maximum considered tsunamis for each area (Inundation Map Methodology (poster)). Click on the county or county name from the list below to view/download that county's Tsunami Inundation Maps. For local, county, or regional emergency preparedness information, explore the links at the bottom of each county's page.
