A simulation of the most likely scenario and effects for the next big earthquake in Southern California.
The magnitude 7.8 scenario earthquake ruptures 186 miles (300 km) of the San Andreas fault from Bombay Beach at the edge of the Salton Sea in the south to Lake Hughes northwest of Palmdale in the north. The final slip (offset across the fault) ranges from 6-23 ft (2-7 m). The colors in the movies indicate the peak intensity of the shaking up to the current time at each location.
This movie shows a view of southern California with the seismic waves radiating outward from the fault as the rupture propagates towards the northwest along the San Andreas fault.
