Shake Map

This figure demonstrates the need for work done by the CABRILLO Project to understand offshore earthquake hazards. Early in 2002, a small magnitude 4.6 earthquake centered 40 miles offshore caused shaking of coastal southern California that was felt from Santa Barbara to Irvine. There are many faults (in red) much closer to shore that, in all likelihood, have the potential to produce devastating magnitude 6 to 7 earthquakes.
