San Andreas Fault

The 1,200 km crack running through California/Geology & Minerals

The San Andreas Fault is a transform plate boundary stretching about 1,200 km through California, marking where the Pacific and North American tectonic plates grind past each other. The fault zone can be up to 1.6 km wide in places. The plates move at an average rate of about 46 mm per year. Major earthquakes along the fault include the devastating 1906 San Francisco earthquake (magnitude 7.9) and the 1857 Fort Tejon earthquake (magnitude 7.9).
