Earthquake Zones In California

California Earthquake Fault Zones Search Page. California Department of Conservation publishes Earthquake Fault Zone Maps on the Internet. But most of people have difficulty reading these maps., a California Natural Hazard Disclosure Company, provides us a simple California Earthquake Fault Zones Map for Google Map application.

State of California. UPLOAD Geologic/Geotechnical Reports of Fault Studies. The Policies and Criteria of the State Mining and Geology Board, with respect to the Alquist-Priolo Earthquake Fault Zoning Act (California Code of Regulations, Section 3603(f)), requires lead agencies to file copies of geologic reports of fault studies with the State Geologist within 30 days of its approval.

The Alquist-Priolo Earthquake Fault Zoning Act was passed in 1972 to mitigate the hazard of surface faulting to structures for human occupancy.

The 2010 Baja California earthquake (also known as 2010 Easter earthquake, 2010 Sierra El Mayor earthquake, or 2010 El Mayor – Cucapah earthquake) occurred on April 4 (Easter Sunday) with a moment magnitude of 7.2 and a maximum Mercalli intensity of VII (Very strong).The shock originated at 15:40:41 local time (3:40:41 PM PDT) south of Guadalupe Victoria, Baja California, Mexico.

An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves.Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities.

Strong Motion Instrumentation Program : Strong Motion Data & Internet Quick Reports. The California Strong Motion Instrumentation Program (CSMIP) records the strong shaking of the ground and structures during California earthquakes.

San Francisco Earthquake, 1906: This earthquake is one of the most devastating in the history of California. The earthquake and resulting fires caused an estimated 3,000 deaths and $524 million in property loss. Damage in San Francisco resulting only from the earthquake was estimated at $20 million; outside the city, it was estimated at $4 million.
