San Andreas Fault

The San Andreas Fault is a continental transform fault that runs a length of roughly 810 miles (1,300 km) through California in the United States. The fault's motion is right-lateral strike-slip (horizontal motion). It forms the tectonic boundary between the Pacific Plate and the North American Plate.

The fault was first identified in Northern California by the UC Berkeley geology professor Andrew Lawson in 1895 and named by him after a small lake which lies in a linear valley formed by the fault just south of San Francisco, the Laguna de San Andreas. After the 1906 San Francisco Earthquake, Lawson also discovered that the San Andreas Fault stretched southward into southern California. Large-scale (hundreds of miles) lateral movement along the fault was first proposed in a 1953 paper by geologists Mason Hill and Thomas Dibblee.

Famous quotes containing the words fault and/or san:

    How utterly futile debauchery seems once it has been accomplished, and what ashes of disgust it leaves in the soul! The pity of it is that the soul outlives the body, or in other words that impression judges sensation and that one thinks about and finds fault with the pleasure one has taken.
    Edmond De Goncourt (1822–1896)

    We had won. Pimps got out of their polished cars and walked the streets of San Francisco only a little uneasy at the unusual exercise. Gamblers, ignoring their sensitive fingers, shook hands with shoeshine boys.... Beauticians spoke to the shipyard workers, who in turn spoke to the easy ladies.... I thought if war did not include killing, I’d like to see one every year. Something like a festival.
    Maya Angelou (b. 1928)
