The 1906 San Francisco earthquake was caused by a rupture on the San Andreas Fault, a major transform fault that runs for over 800 miles through California. The earthquake is believed to have been triggered by a sudden release of stress that had built up over time as the Pacific Plate and the North American Plate moved past each other. The epicenter of the earthquake was located near San Francisco, and the quake is estimated to have had a magnitude of 7.9 on the Richter scale.
