Seismic Hazards Program

Description / purpose

The Seismic Hazards Program delineates areas prone to ground failure and other earthquake-related hazards including soil liquefaction (the failure of water-saturated soil), earthquake-induced landslides, surface fault rupture, and tsunami inundation. Cities and counties are required to use these maps in their land-use planning and building permit processes so that these hazards are identified and mitigated for development projects prior to the next major earthquake. Additionally, the program reviews and provides comments on geologic and seismic hazards that apply directly to the design and construction of essential and critical facilities around the state. These facilities include schools, hospitals, nuclear power plants, hazardous waste repositories, and others, typically under contract to other state agencies. The program compiles information about past earthquakes, the potential for earthquakes on major faults, and rates of deformation across California to estimate the potential for future earthquakes. The Seismic Hazards Program works closely with the U.S. Geological Survey to produce earthquake shaking maps that are used in development of building codes and in earthquake damage and loss estimates.
