Question

Quizplus · Accepted Answer

A sudden slip on an existing fault causes the most earthquakes. The movement of tectonic plates along a fault line causes stress to build up, and when that stress is suddenly released, it can cause an earthquake. This release of energy is often the result of a sudden slip on an existing fault, as opposed to the sudden formation of a new fault, an explosion of a volcano, or a giant landslide.
