Earthquake hazard maps show the probability that ground shaking will exceed a certain level over a 50-year period. For example, low-hazard areas have a 2% chance of exceeding a designated low level of shaking. ... Earthquake activity in California along the San Andreas Fault—the boundary between the Pacific and North American plates—is a ...Assuming a fault model whereby the repeat time T of earthquakes on each fault equals M 0 e /M 0 g (where the moment rate M 0 g is proportional to fault slip rate), it is observed that the moment-frequency distribution of earthquakes predicted from the geologic data agrees well with the distribution determined from a 150-year historical record ...The California Geological Survey produces maps of active faults and establishes Earthquake Zones of Required Investigation surrounding these faults. The Hospital Safety Act of 1972 requires, in part, the consideration of geological and seismological issues to ensure new or retrofitted hospital buildings are sited, designed, and constructed to ...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 ...A number of different earthquakes are possible in the Bay Area. The Hazard Viewer offers 16 unique shaking scenarios to help visualize how individual shaking scenarios might impact your area. To identify the earthquake fault segments that contribute most to each area's shaking hazard earthquake risk, use the "Earthquake Deaggregation" map.
