The earthquakes that have happened in the meantime are still devastating to a local area, but instead of magnitude eight, they're more like magnitude seven. If the Big One on the San Andreas fault is the main shock, it could be followed by large aftershocks (or preceded by foreshocks) at any time, killing and injuring more people and causing more damage. According to the theory of plate tectonics, the San Andreas Fault represents the transform (strike-slip) boundary between two major plates of the Earths crust: the Northern Pacific to the south and west and the North American to the north and east. According to the. Vidale: We haven't had a big earthquake in Southern California really since 1857. What happens if San Andreas fault breaks? - TimesMojo San Andreas Fault, major fracture of the Earths crust in extreme western North America.
