California is Earthquake Country

On average a damaging earthquake strikes somewhere in California every two years. Since 1987, however, Southern California alone has been hit by at least nine damaging quakes. 

Seismologists believe that a major earthquake - magnitude 7 or greater - is likely to occur somewhere in Southern California within the next 30 years.

Because the San Andreas Fault is the longest fault in the region, it produces the largest earthquakes. Scientists estimate that large earthquakes on the San Andreas occur about every 130 years. The largest earthquake on the southern portion of the San Andreas in recorded history occurred in 1857. The fault ruptured all the way from Parkfield in southern Monterey County to Cajon Creek in San Bernardino County. Scientists estimate its magnitude at 7.8.

Recent events have shown that earthquakes on other faults can have considerable impacts. The Northridge earthquake in 1994 caused 57 deaths, more than 90,000 injuries and $40-42 billion in property losses. Scientists estimate that more than 200 faults in the area are capable of causing an earthquake of magnitude 6 or greater. Most everyone in Southern California lives within 30 miles of one of these faults. 

No one knows when or where such a quake will occur, but everyone can reduce their risk of death, injury and property loss in an earthquake by using the recommendations outlined here wherever you live, work or play.
