Map of fault lines in california
The fault dimensions (length and width) and the amount of slip vary dramatically across the spectrum of earthquake magnitudes. For example, an M w 4 earthquake fault commonly has a length of around 1 km, an M w 7 earthquake has a length of around 40 km, and the 2004 M w 9.1 Sumatra earthquake had a rupture length of over 1000 km.California won't fall into the ocean, but it could get nudged hundreds of miles offshore, making Nevada the new coastline of the continent, scientists at the University of Nevada, Reno hypothesize.The third and final place the fault crosses I-5 is just south of Gorman. This view looks east: The San Andreas generally follows the valley on the south side of Tejon Pass. The surface trace is not visible in most places, with the 1857 earthquake surface rupture long erased by 160 years of erosion and road construction.
