Jun 12, 2010 · Abstract. Modern earthquake ground motion hazard mapping in California began following the 1971 San Fernando earthquake in the Los Angeles metropolitan area of southern California. Earthquake hazard assessment followed a traditional approach, later called Deterministic Seismic Hazard Analysis (DSHA) in order to distinguish it from the newer ...

Nov 27, 2023 · The 2023 SHMP replaces the 2018 SHMP and will expire on August 29, 2028. At the time of plan approval, the Federal Emergency Management Agency (FEMA) recognized California as one of 14 states to earn the designation of an “Enhanced” State.
hazards in the latest edition of the California Building Code, have necessitated additional changes for consistency. To avoid confusion with the previous 2008 release, this document carries the designation ―Special Publication 117A.‖ More than ten years have passed since these Guidelines were first published, during which time

A Seismic Hazard Zone is a regulatory zone that encompasses areas prone to liquefaction (failure of water-saturated soil) and earthquake-induced landslides. 1. Liquefaction occurs when loose, water-saturated sediments lose strength and fail during strong ground shaking. Liquefaction is defined as the transformation of granular material from a sol...
It means that the state has determined that there is likely that weak soil and/or rock may be present beneath the property. If present, these weak materials can fail during an earthquake and, unless proper precautions are taken during grading and construction, can cause damage to structures. If a property is undeveloped, a site-specific investigati...
Effective June 1, 1998 (as amended June 9, 1998), the Natural Hazards Disclosure Act requires that sellers of real property and their agents provide prospective buyers with a "Natural Hazard Disclosure Statement" when the property being sold lies within one or more state-mapped hazard areas. If a property is located in a Seismic Hazard Zone as show...
Official Maps of Seismic Hazard Zones are issued periodically by the California Geological Survey in compliance with the Seismic Hazard Mapping Act. The easiest way is to find out if a property is located in a Seismic Hazard Zone is to use the California Earthquake Hazards Zone Application or search our collection of online maps. You can also v...
Staff geologists in the Seismic Hazards Program (Program) gather existing geological, geophysical and geotechnical data from numerous sources to compile Seismic Hazard Zone Maps. They integrate and interpret these data regionally in order to evaluate the severity of the seismic hazards and designate Zones of Required Investigation for areas prone t...
The SHMA requires site-specific geotechnical investigations be conducted identifying the hazard and formulating mitigation measures prior to permitting most developments designed for human occupancy within the Zones of Required Investigation. Before a development permit can be issued or a subdivision approved, cities and counties must require a sit...
