A ground/earth fault is a fault where part of the current returns back through a path other than the opposing hot or, more critically, neutral. A neutral/earth fault is dangerous because the circuit will continue to function normally, but the hot and neutral leg currents are imbalanced, and the chassis can become energized.
Earthquakes occur on faults. A fault is a thin zone of crushed rock separating blocks of the earth's crust. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
