==Earthquakes==
The [[1994 Northridge earthquake]] was named for Northridge based on early estimates of the location of the quake's [[epicenter]]; however, further refinements showed it to be technically in neighboring [[Reseda, Los Angeles|Reseda]].<ref>{{cite web | title = January 17, 1994 northridge earthquake | publisher = National Geophysical Data Center | url = http://www.ngdc.noaa.gov/hazardimages/event/show/18 | archive-url = https://web.archive.org/web/20130218022042/http://ngdc.noaa.gov/hazardimages/event/show/18 | url-status = dead | archive-date = February 18, 2013 | access-date = October 9, 2013}}</ref>  The earthquake, which occurred on a [[blind thrust fault]], was one of the strongest ground motions ever recorded in North America. Freeways collapsed, and many  buildings suffered irreparable damages. Vertical and horizontal accelerations lifted structures off their foundations.<ref>{{cite web|url=http://www.data.scec.org/significant/northridge1994.html|title=Southern California Earthquake Data Center at Caltech|access-date=2012-11-13|archive-url=https://web.archive.org/web/20141006115519/http://www.data.scec.org/significant/northridge1994.html|archive-date=2014-10-06|url-status=dead}}</ref> During the 1994 quake, the Northridge Hospital Medical Center remained open and treated more  than 1,000 patients who came to the facility during the first few days after the magnitude 6.7 quake.<ref name=WhoWeAre/>

This was the second time in 23 years that the area had been affected by a strong earthquake. On February 9, 1971, the [[San Fernando earthquake]] (also known as the Sylmar earthquake) struck, having a magnitude of 6.5.<ref>{{cite web| url=http://www.data.scec.org/significant/sanfernando1971.html| title=San Fernando Earthquake| publisher=Southern California Earthquake Data Center| access-date=October 14, 2013| archive-url=https://web.archive.org/web/20140407061651/http://www.data.scec.org/significant/sanfernando1971.html| archive-date=April 7, 2014| url-status=dead}}</ref>
