Earthquake Zones Bay Area

This map shows the composite shaking hazard across the Bay Area based on all earthquake scenarios and likelihood information using the Modified Mercalli Intensity (MMI) scale.

Update | An earthquake struck the Bay Area early Thursday morning along a fault line that U.S. Geological Survey scientists have called a “tectonic time bomb.” The earthquake hit near Berkeley, California, as a magnitude 4.4. The damage is expected to be minimal, but it occurred along the ...

California isn’t the only state with a serious earthquake hazard. There are several lesser-known fault zones lurking in other parts of the country that are just as dangerous, if not more dangerous, than the famed San Andreas Fault.

Availability: Entire US Back to Top . AP (Alquist-Priolo) Fault Zones This report shows you whether or nor a property falls into an Alquist-Priolo Fault Zone. AP Fault Zones are designated by the California Department of Mines & Geology as areas near active faults.
