The San Andreas Fault is a major geological fault located in California, USA. It is a transform fault, which means it is a boundary between two tectonic plates that are sliding horizontally past each other. The San Andreas Fault extends for about 800 miles (1,300 kilometers) through California, from the Salton Sea in the south to Cape Mendocino in the north.
The San Andreas Fault is associated with the boundary between the Pacific Plate and the North American Plate. The Pacific Plate is moving northwestward relative to the North American Plate, and the two plates are sliding past each other horizontally. This movement along the fault can result in earthquakes, as the plates are locked and then suddenly slip past each other, releasing stored energy in the form of seismic waves.
The San Andreas Fault is known for its long history of seismic activity, and it has been responsible for some of the most significant earthquakes in California’s history, including the 1906 San Francisco earthquake. It is closely monitored by seismologists and geologists due to the potential for future earthquakes along the fault. The San Andreas Fault also serves as an important natural laboratory for studying fault mechanics, earthquake processes, and tectonic plate interactions.
