The San Andreas Fault has had some notable earthquakes in historic times:

* [[1812 San Juan Capistrano earthquake]]: At least 25 kilometers(16&nbsp;mi) were ruptured in Southern California. Several of the Roman Catholic missions in the area experienced heavy damage.<ref>{{Cite book |last=Stover |first=Carl W. |url=https://books.google.com/books?id=bY0KAQAAIAAJ |title=Seismicity of the United States, 1568-1989 (revised) |last2=Coffman |first2=Jerry L. |date=1993 |publisher=U.S. Government Printing Office |language=en}}</ref> Early studies indicated the earthquake was on the [[Newport–Inglewood Fault|Newport-Inglewood fault]] due to the proximity of the damage, but a later study in 2002 indicated the San Andreas fault was the cause. More recent studies suggest a joint rupture which included both the San Andreas Fault, and [[San Jacinto Fault Zone|San Jacinto Fault]] are more accepted scenarios. Around 40 people died, and the magnitude ranged from 6.9 to 7.5.<ref>{{Cite web |title=Wrightwood's 1812 Earthquake Article |url=https://www.wrightwoodcalif.com/ww1812quake.html#:~:text=Geologic%20investigations%20and%20historic%20accounts,south%20as%20San%20Bernardino%20Valley. |access-date=2025-01-12 |website=www.wrightwoodcalif.com}}</ref>
* [[1857 Fort Tejon earthquake]]: About {{convert|350|km|mi|sp=us}} were ruptured in central and southern California. Though it is known as the [[Fort Tejon]] earthquake, the epicenter is thought to have been located far to the north, just south of [[Parkfield, California|Parkfield]]. Two deaths were reported. Its [[Moment magnitude scale|moment magnitude]] was 7.9.
* [[1906 San Francisco earthquake]]: About {{convert|430|km|mi|sp=us}} were ruptured in Northern California. The epicenter was near [[San Francisco]]. At least 3,000 people died in the earthquake and subsequent fires. The magnitude was estimated to be 7.8.
* [[1957 San Francisco earthquake]]: A magnitude 5.7 quake with an epicenter on the San Andreas fault in the ocean west of San Francisco and Daly City.
* [[1989 Loma Prieta earthquake]]: About {{convert|40|km|mi|sp=us}} were ruptured (although the rupture did not reach the surface) near [[Santa Cruz, California]], causing 63 deaths and moderate damage in certain vulnerable locations in the San Francisco Bay Area. [[Moment magnitude scale|Moment magnitude]] was about 6.9. This quake occurred on October 17, 1989, at approximately 5:04&nbsp;pm PDT.
* [[Parkfield earthquake#2004 event|2004 Parkfield earthquake]]: On September 28, 2004, at 10:15&nbsp;a.m. PDT, a magnitude 6.0 earthquake struck the Parkfield area. It was felt across the state, including the San Francisco Bay Area.
