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.

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.
