The 1906 earthquake, which devastated most of San Francisco, left a visible gap all along the San Andreas Fault line, which can still be seen today. Located at the border between the North American Plate and the Pacific Plate, the San Andreas Fault is among the most known active faults on the planet. It was named so after the San Andreas Lake that was formed as a result of the fault, which was discovered in 1895 by geologist Andrew Lawson of the University of California, Berkeley.
