Earthquake hazard zones define areas subject to three distinct types of geologic ground failures: Although strong ground shaking is responsible for most earthquake-related damage, these zones identify areas where earthquake hazards other than structural shaking — specifically ground failures during an earthquake — are more likely. The zones trigger geologic and engineering investigations that can identify and mitigate the ground failure hazard before construction begins, thereby making the structure itself more resilient to potential shaking.In California, there are environmental and earthquake hazard disclosure requirements for sellers of residential real estate.
Although aspects of these new methodologies may be incorporated in future CGS seismic hazard zone maps, USGS maps should not be used as substitutes for Official CGS Seismic Hazard Zones maps.Information on the map is not sufficient to serve as a substitute for the geologic and geotechnical site investigations required under Chapters 7.5 and 7.8 of Division 2 of the California Public Resources Code.Seismic Hazard Zones identified on the map may include developed land where delineated hazards have already been mitigated to city or county standards.

Also, a single earthquake capable of causing liquefaction or triggering landside failure will not uniformly affect the entire area zoned.Faults shown are the basis for establishing the boundaries of the Earthquake Fault Zones.The identification and location of faults are based on the best available data. Here are some moments from that special day.We would like to hear from you regarding our decision to deny a hazardous waste facility permit renewal application for General Environmental Management.

The Marine Life Protection Act (MLPA) was passed in 1999 by the California Legislature, directing the California Department of Fish and Wildlife (CDFW) to redesign California’s existing system of marine protected areas (MPAs) to increase its coherence and effectiveness for protecting the state’s marine life, habitats, and ecosystems. Assess hazard zones where you live with this earthquake fault and liquefaction zone map. This situation typically exists at or near the toes of existing landslides, downslope from rockfall or debris flow source areas, or adjacent to steep stream banks.Landslide zones on the map were determined, in part, by adapting methods first developed by the U.S. Geological Survey (USGS). Check with your local building/planning department for information regarding the location of such mitigated areas.The parcel data provided on the map are updated semi-annually and may be outdated at the time they are viewed on this application. Twitter YouTube The State of California and the Department of Conservation make no representations or warranties regarding the accuracy of these data or maps. If you're interested in finding out if you live in an earthquake liquefaction zone, the California Conservation Corps has an interactive map that shows where these zones are. Liquefaction occurs when saturated sandy soils are shaken during an earthquake. In addition, the use of maps, related data, or other information that the Department may furnish does not limit, abridge, or necessarily fulfill any obligation for disclosure created by the Alquist-Priolo Earthquake Fault Zoning Act, the Seismic Hazards Mapping Act, or any other provision of law.
