This figure shows the four to six foot fault scarp of the Landers earthquake. The ground rupture, initiated on the Johnson Valley Fault west of Landers, traveled northward along a series of northwest trending faults and terminated in the Rodman Mountains south of Barstow. Measurements indicate a movement along the fault line a maximum of 18 feet horizontally and six feet vertically. The width of the rupture zone appeared to range from eleven feet at the narrowest point to 140 feet across at the widest point. Image Credit: Lindie Brewer.
