The fault that triggered the quake was probably located on one of the many faults south of the San Andreas fault, [seismologist Lucy] Jones said. The fault is probably about 40 to 50 miles long, and probably shook for 20 to 30 seconds. The worst shaking would have occurred closest to the fault, said [seismologist Lucy] Jones .
She said scientists would not have enough information to identify the fault until geologists survey the area.
The quake occurred at the junction between two tectonic plates, the Pacific and the North American, that grind against each other through Baja California and California. The quake is probably on a strike-slip fault, which splices through the ground vertically and causes land to move horizontally.
