One magnitude 7.0 quake along the fault perhaps 550 years ago dropped the ground on one side of the fault by three feet (a meter). A reverse is, well, just the reverse.Īn example of a normal fault is the 240-mile (150-kilometer) long Wasatch Fault underlying parts of Utah and Idaho, again caused by the Pacific plate driving under western North America. A normal fault occurs where the deeper part of the crust is pulling away from an overlying part. Up-and-down motions in earthquakes occur over so-called "dip-slip" faults, where the ground above the fault zone either drops (a normal fault) or is pushed up (a reverse fault). The sideways motion of the fault's branches is caused by the Pacific Ocean's crustal plate moving to the northwest under North America's continental crust. The most famous example is California's San Andreas Fault, which stretches some 600 miles (1,000 kilometers) from southern California to north of San Francisco. When portions of the Earth's crust moves sideways, the result is a horizontal motion along a "strike-slip" fault. There are several different types of faults, including a normal dip slip fault, reverse fault, and strike-slip fault.

How much does earthquake insurance cost in California? Given the large number of damage-causing earthquakes in California each year, it is wise to carefully consider doing so. You must purchase a separate policy to get coverage. Homeowners insurance will not cover earthquakes. However, California law makes it mandatory for providers like State Farm and Allstate to proactively offer earthquake insurance in conjunction with a homeowners insurance policy to new homebuyers, according to Pomeroy.
