The power of the earthquake was illustrated by the length of the ground rupture it left behind. The earthquake ruptured 5 separate faults: Johnson Valley, Landers, Homestead Valley, Emerson, and Camp Rock faults. The total rupture length was ~85km (53 miles), and the faults slipped from 2 meters (~6 ft) to a maximum of 6 meters (~18 ft).Historical Earthquakes & Significant Faults in Southern CA.
