San Andreas Fault is a geological fault that spans a length of roughly 1,300 kilometres through California in the United States.
Large faults within the Earth's crust are the result of motion and active fault zones are the causal locations of most earthquakes.
Earthquakes are caused by energy release during rapid slippage along faults.
The San Andreas Fault, a right-lateral strike-slip fault, marks a transform boundary between the Pacific Plate and the North American Plate.
All land west of the fault on the Pacific Plate is moving slowly to the northwest while all land east of the fault is moving to the southwest under the influence of plate tectonics. The rate of slippage is approximately of 0.6 cm a year.
