The San Diego Seismic Safety Study

The San Diego Seismic Safety Study is a series of maps that indicate the likely geologic hazards throughout the city. These maps may be used to evaluate the relative risk within a region or to determine if a geotechnical report is required for development or building permits.

The California Department of Conservation continuously updates the Alquist-Priolo Earthquake Fault Zones (City of San Diego - Geologic Hazard Category 11) within the State of California. 

For the most up-to-date limits of the Alquist-Priolo Earthquake Fault Zone, please refer to the Earthquake Hazard Zone map.

These maps do not furnish site-specific information and should be used only as a guide when evaluating risk. They are intended to be an indicator of what to expect at your site and provide general geologic hazard information.
