Geologic fault

Geologic faults or simply faults are planar rock fractures which show evidence of relative movement.

Large faults within the Earth's crust are the result of shear motion and active fault zones are the causal locations of most earthquakes.

Earthquakes are caused by energy release during rapid slippage along faults.
