Heres what could happen in Southern California if a large earthquake struck on the San Andreas fault. Using P-wave information, ShakeAlert first estimates the location and the magnitude of the earthquake. Also called a temblor, an earthquake is caused by the movement of parts of the Earth's crust, its outermost layer. This estimate is imperfect, as a large earthquake can take more than a minute to reach its full magnitude.
