Observations of faulting after the 1906 San Francisco earthquake. Fences were offset by 3 meters or more over nearly 400 km distance of the fault. The fault left a “mole track” across the landscape. This is called a strike-slip earthquake. There are several important strike-slip faults on the eastern side of the Sierra Nevada mountains, including faults in Death Valley which are capable of causing strong shaking in Las Vegas.
