What fault caused the 1994 Northridge earthquake?
thrust faults
Northridge California Earthquake 1994 Summary The thrust faults along which the 1971, 1987, and 1994 earthquakes occurred are the result of a big bend in the San Andreas fault. The bend causes crumpling, or “compression” of the Earth’s crust nearby, giving rise to the thrust faults.

The Northridge earthquake occurred on a blind thrust fault—a buried thrust fault that does not extend to the surface. The individual faults in the zone move more slowly than the San Andreas fault and produce smaller earthquakes than those expected on the San Andreas fault.
