In California law, Alquist-Priolo Earthquake Fault Zone Act of 1971 defines an active fault is one that has ruptured in the last 11,000 years. That date is a bit nebulous in reality because faults move in many ways and at different times and different places, sometime creeping slowly, or suddenly during an earthquake.
