Earthquakes that contribute most to the seismic hazard of California


The seismic hazard model used in producing hazard maps for the State of California implies that the hazard is high over much of coastal California and the eastern California shear zone and is lower in the Central Valley. Large to great earthquakes (M 7.5-9) contribute most to the hazard in the northwest portion of the state, in the vicinity of the San Andreas fault zone, and across much of the Central Valley. Large earthquakes (M 6.5-7.5) on local faults cause the predominant hazard near the eastern San Francisco Bay and the greater Los Angeles region. Moderate earthquakes of M<6.5 contribute to only small areas located across eastern California.
