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.
Strike-slip faults are usually vertical, while normal and reverse faults are often at an angle to the surface of the Earth. The different styles of faulting can also combine in a single event, with one fault moving in both a vertical and strike-slip motion during an earthquake.
