Editing Garlock Fault (section)

== Activity ==
The Garlock Fault moves at a rate of between 2 and 11&nbsp;mm a year, with an average slip of around 7 millimeters. While most of the fault is locked, certain segments have been shown to move by [[aseismic creep]], which is motion without resulting earthquakes.

The Garlock is not considered to be a particularly [[active fault]], seldom producing any shaking detectable by humans, although it has been known to generate sympathetic [[Seismology|seismic events]] when triggered by other [[earthquake]]s and in one instance by the removal of [[groundwater|ground water]]. These events, as well as continuing [[microearthquake]] activity and the state of the [[fault scarp|scarps]] from previous ruptures, do indicate that the Garlock will produce another major quake at some point in the future.<ref>{{cite journal|url=http://bssa.geoscienceworld.org/cgi/content/abstract/73/6A/1721 |title=Seismicity of the Garlock fault, California |first1=L.|last1=Astiz|first2=C.

A study published in October 2019 in the journal ''[[Science (journal)|Science]]'' indicated that a part of the Garlock fault slipped after being triggered by the [[2019 Ridgecrest earthquakes|series of earthquakes in the Ridgecrest area]] which occurred in July 2019.<ref name=Time20181018>{{cite web|url=https://time.com/5705085/garlock-fault-ridgecrest-earthquake-california/|title=Scientists: Movement Detected Along California Fault That Could Cause an 8-Magnitude Earthquake|date=October 18, 2019|website=Time}}</ref> Reports in the [[Los Angeles Times]] indicated that a magnitude 8 earthquake along the Garlock fault would have the potential for grave disaster.<ref name=Time20181018 />

The last significant ruptures on the Garlock were thought to be in the years 1050 AD and 1500 AD. Research has pinned the interval between significant ruptures on the Garlock as being anywhere between 200 and 3,000 years, depending on the segment of the fault.<ref name=bigone>{{cite news|url=http://www.latimes.com/local/lanow/la-me-ln-earthquake-fault-cluster-20150422-story.html|title=The Big One could trigger series of large earthquakes, study finds|work=Los Angeles Times|date= April 22, 2015|first= Rong-Gong |last= Lin II}}</ref> The most recent notable event in the Garlock Fault Zone was a magnitude 5.7 near the town of [[Mojave, California|Mojave]] on July 11, 1992.<ref name="SCEDC Major Faults"/> It is thought to have been triggered by the [[1992 Landers earthquake|Landers earthquake]], just two weeks earlier.<ref name="SCEDC Major Faults">{{cite web |title=Garlock Fault Zone |url=https://scedc.caltech.edu/significant/garlock.html |publisher=Southern California Earthquake Data Center |access-date=17 October 2019}}</ref> However, no surface slippage of the fault itself had been recorded in modern times until 2019.
