Editing Burbank, California (section)

===Geology===
The geology of the Burbank area is primarily composed of sedimentary rocks, including sandstone, siltstone, and shale. These rocks were formed by sediment deposited by ancient rivers and seas, and have been uplifted and folded due to tectonic activity. Burbank is located within a seismically active area. At least eight major faults are mapped within {{convert|13.5|mi}} of Burbank's civic center. The San Fernando Fault, located {{convert|6|mi|0}} northwest of Burbank's downtown, caused the 6.6 magnitude [[1971 San Fernando earthquake]].

The Verdugo Fault, which can reach a maximum estimated 6.5 magnitude earthquake on the [[Richter Scale]], is about {{convert|1.5|mi}} from the city of Burbank's civic center. This fault extends throughout the city and is located in the alluvium just south of the Verdugo Mountains. The fault is mapped on the surface in northeastern Glendale, and at various locations in Burbank. Other nearby faults include the Northridge Hills Fault ({{convert|10|mi|0}} northwest of Burbank), the [[Newport–Inglewood Fault]] ({{convert|12.5|mi}}), Whittier Fault ({{convert|21|mi}}), and lastly the [[San Andreas Fault]] ({{convert|28|mi}}) with its 8.25 magnitude potential on the Richter Scale.<ref>{{cite book | chapter-url = http://www.burbankca.org/planning/pdf/genplan/draft2006/eir/section5-5.pdf | chapter = Geology and Soils | title = Land Use and Mobility Elements Update: City of Burbank Draft Program EIR | date = April 2006 | access-date = August 19, 2009 }} {{Dead link|date=June 2022 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

The [[1971 San Fernando earthquake]], with a magnitude of 6.6, caused some damage in Burbank. Poorly reinforced and unreinforced masonry fences were damaged as well as masonry chimneys. Pacific Manor care facility on Glenoaks, which was later razed and replaced with a new care facility, was badly damaged and had to be evacuated. Some factories, including Lockheed, had spills of hazardous materials. There were also small fires from electrical or fuel gas-related sources. Lastly, there were cases of flooding in buildings due to broken pipes and risers used for fire sprinklers.<ref name=mybur_Feb10>{{cite news|title=A Look Back At The Big Quake That Shook Burbank 40 Years Ago|url=https://myburbank.com/a-look-back-at-the-big-quake-that-shook-burbank-40-years-ago/|first=Craig|last=Sherwood|date=February 10, 2011|newspaper=MyBurbank.com}}</ref>

Burbank suffered $66.1 million in damage from the [[1994 Northridge earthquake]], according to the city's finance department. There was $58 million in damage to privately owned facilities in commercial, industrial, manufacturing and entertainment businesses. Another $8.1 million in losses included damaged public buildings, roadways and a power station in Sylmar that is partly owned by Burbank. The Burbank Fire Department responded to 292 calls for damage inspections and reports of natural gas leaks. The damage caused was more extensive than the 1971 San Fernando earthquake but still relatively moderate in nature.<ref>{{cite web|url=https://www.burbankfire.us/home/showpublisheddocument/88/634977218427430000#:~:text=There%20was%20one%20significant%20fire,in%20damages%20to%20private%20facilities|title=Regional All-Hazard Burbank CH-6_Earthquake |date=March 14, 2011 | first=Kenneth | last=Goettel | access-date=January 21, 2023}}</ref><ref>{{cite web|url=http://burbank.granicus.com/MetaViewer.php?view_id=6&clip_id=2519&meta_id=108398|title=City of Burbank All-Hazard Mitigation Plan |date=April 2011 | first=Kenneth | last=Goettel | access-date=January 21, 2023}}</ref>
