Detailed explanation-1: -California has more earthquakes that cause damage than any other state. Alaska and California have the most earthquakes (not human-induced).

Detailed explanation-2: -Central Coast. This region has a long history of damaging earthquakes. Large earthquakes will occur along the San Andreas fault system-the major geologic boundary between the North American and Pacific tectonic plates-which passes through much of the State of California.

Detailed explanation-3: -Each year, California generally gets two or three earthquakes large enough to cause moderate damage to structures (magnitude 5.5 and higher). Earthquakes can occur at any time of the year.

Detailed explanation-4: -California is home to two-thirds of our nation’s earthquake risk. We all know that California is earthquake country. But do you know your local risk? Learn about earthquake faults in your area, and discover the disruptions that could occur after a big quake.

Detailed explanation-5: -Since the formation of the San Andreas Fault system 25-30 million years ago, the juxtaposition of the Pacific and North American plates has formed many faults in California that accommodate lateral motion between the plates.
