Supershear earthquakes are more likely to happen along long, mature faults like the San Andreas, where many years of activity have ground away a lot of the twists and bumps that might slow down an earthquakes energy. This can be done by detecting the first energy to radiate from an earthquake, the Primary (P) wave energy, which rarely causes damage. It can also prevent cascading failures in the aftermath of an event. Also called a temblor, an earthquake is caused by the movement of parts of the Earth's crust, its outermost layer.
