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.
A reverse fault is one in which one side of the fault, the hanging wall, moves up and over the other side, the foot wall. This movement is caused by compression and is common at tectonic plate boundaries. A thrust fault is a reverse fault that is at an incline of less than 45 degrees.
