Aerial photograph of Pipes Wash and Landers, San Bernardino County, California. Just beyond the flat, basalt-topped mesas in this view is the Johnson Valley Fault, which along with several other faults, ruptured during the 1992 Landers earthquake. The Johnson Valley Fault extends from about 3 o'clock to about 10 o'clock; surface faulting associated with the 1992 earthquake ruptured along multiple faults across the valley near the upper left in this view to reach the Homestead Valley Fault, which also slipped in the earthquake. The constriction in Pipes Wash near the center of the image, is controlled by slippage of the Johnson Valley Fault. View to the northeast.
