The '''1933 Long Beach earthquake''' took place on March 10 at {{tooltip|5:54 P.M. PST|March 11, 01:54 UTC}} south of [[Downtown Los Angeles|downtown]] [[Los Angeles]]. The epicenter was offshore, southeast of [[Long Beach, California|Long Beach]], [[California]], on the [[Newport–Inglewood Fault]].<ref>{{Cite web|title=Southern California Earthquake Data Center: Long Beach Earthquake|url=https://scedc.caltech.edu/earthquake/longbeach1933.html|access-date=2021-05-01|website=scedc.caltech.edu}}</ref> The [[earthquake]] had a magnitude estimated at 6.4 {{m|w|link=y}}, and a maximum [[Mercalli intensity scale|Mercalli intensity]] of VIII (''Severe''). Damage to buildings was widespread throughout [[Southern California]]. It resulted in 115 to 120 fatalities and an estimated $40 million worth of property damage, equivalent to ${{inflation|US|40|1933}}&nbsp;million in {{Inflation/year|US}}. The majority of the fatalities resulted from people running out of buildings exposing themselves to the falling debris.

Major damage occurred in the densely populated city of Long Beach on the south-facing coast of [[Los Angeles County]]. However, the damage was also found in the industrial area south of [[downtown Los Angeles]]. An estimated 75,000&nbsp;mi<sup>2</sup> area was impacted, being felt as far as [[San Joaquin Valley]], [[Owens Valley]], and Northern [[Baja California]]. 

The magnitude of the earthquake is considered medium, but a significant amount of damage occurred due to unfavorable geological conditions (landfill, water-soaked [[alluvium]]) combined with poorly constructed buildings. In Long Beach, buildings collapsed, water tanks fell through roofs, and houses were tossed off their [[Foundation (engineering)|foundations]]. School buildings were among the structures that incurred the most severe damage.<ref name="neic">{{USGS|archiveurl=https://web.archive.org/web/20000817021801/http://neic.usgs.gov/neis/states/california/california_history.html|archivedate=2000-08-17|url=http://neic.usgs.gov/neis/states/california/california_history.html|title=Earthquake History of California|access-date=2018-05-02|url-status=live}}</ref> Within seconds, 120 schools within the Long Beach area were damaged, 70 of which were destroyed. It was recognized that [[Unreinforced masonry building|unreinforced masonry]] bearing walls were the reason that school buildings suffered so much damage.<ref>{{Cite journal|year=1988|title=Building Codes: Evaluating Buildings in Seismic Zones|journal=APT Bulletin|volume=20|issue=2|pages=13–17|jstor=1494245|last1=Green|first1=Melvyn|last2=Watson|first2=Anne L.|doi=10.2307/1494245}}</ref> 

On March 20, 2008, a ''Los Angeles Times'' article stated that "the 1933 quake changed the landscape, leading to improved school construction standards and a heightened awareness of earthquake risks."<ref>{{Cite web|date=2019-03-08|title=From the Archives: The 1933 Long Beach earthquake|url=https://www.latimes.com/visuals/photography/la-me-fw-archives-the-1933-long-beach-earthquake-20190205-htmlstory.html|access-date=2021-11-17|website=Los Angeles Times}}</ref> Among other buildings, the [[La Grande Station]], the main Los Angeles terminal of the [[Atchison, Topeka, and Santa Fe Railroad]], was heavily damaged.<ref name="SCI-Arc">{{cite web|author=Southern California Institute of Architecture |url=http://www.sciarc.edu/v5/about/freightyard.php |title=On the History of the Santa Fe Freight Depot, Los Angeles |year=2004 |accessdate=2006-05-12 |archiveurl=https://web.archive.org/web/20060427000402/http://www.sciarc.edu/v5/about/freightyard.php |archivedate=2006-04-27 |url-status=dead }}</ref>

==Aftermath==
The earthquake highlighted the need for earthquake-resistant design for structures in California. More than 230 school buildings either were destroyed, suffered major damage, or were judged unsafe to occupy. Casualties would have been much higher had the earthquake occurred a few hours earlier while school was in session. Many schools were permanently closed for a long time due to the building being unsafe for inhabitation or not meeting earthquake safety regulations at the time. Since these schools were deemed unsafe, students would report to classes held in tents. Large sums of money were needed to upgrade these damaged school buildings.<ref>{{Cite journal|last=J.

Only 30 days after the earthquake, Governor [[James Rolph|James Rolph Jr]]. signed the [[Field Act]] to govern the planning, design and construction of public school buildings.<ref name="CSSC">{{Cite web |last=Alquist |first=A.

A group of local scientists, architects, and builders formed a Joint Technical Committee on Earthquake Protection to propose ways to minimize loss of life and property in future earthquakes. The committee was chaired by [[California Institute of Technology|CalTech]] physicist [[Robert Andrews Millikan|Robert Millikan]], and included architects [[John C. Austin]] and [[Sumner Hunt]]. In June 1933 they released their report, which advocated for stronger building codes.

The [[Federal Highway Administration|Bureau of Public Roads]] also took action to rebuild roads, highways, and bridges.<ref name="Batten">{{citation |last=Batten |first=Donna |title="Natural Disasters."

To support the [[World War II]] efforts, Long Beach created [[Long Beach Naval Shipyard|naval yards]] and increased the number of aircraft produced. This directly helped Long Beach repair and stabilize the economy after the disaster.<ref name="Johnson">{{citation |last=Johnson |first=Daniel J |title=Long Beach.

This earthquake prompted the federal government to play an active role in disaster relief. The government created the [[Reconstruction Finance Corporation]], providing loans for reconstructing buildings that were affected during the natural disaster.

The damage to the La Grande Station indirectly led to the construction of [[Union Station (Los Angeles)|Los Angeles Union Station]], which was built on top of what was at that time the [[Chinatown, Los Angeles]].<ref>{{Cite web|last=Chang|first=Irene|date=1990-11-14|title=Metro Rail Excavation Casts New Light on 'Old Chinatown'|url=https://www.latimes.com/archives/la-xpm-1990-11-14-me-4046-story.html|url-status=live|access-date=2021-12-18|website=Los Angeles Times|archive-url=https://web.archive.org/web/20200825042752/https://www.latimes.com/archives/la-xpm-1990-11-14-me-4046-story.html |archive-date=2020-08-25 }}</ref>

[[File:Borderlands active faults page.jpg|thumb|The epicenter and its relative location to offshore faults]]

Other studies done by the USGS have also indicated that oil drilling may have been responsible for earthquakes in the surrounding areas in the 1920s.

Within the Los Angeles depositional basin, northwest-trending groups of faulted [[anticline]]s were viewed to be caused by oil and gas extraction underneath the city. The extraction of oil and gas produces salty water,{{Clarify|reason=How does oil and gas extraction produce salty water? A byproduct of the process?|date=March 2022}} adding stress to faults, causing earthquakes.

The [[Newport–Inglewood Fault]], the source of the 1933 earthquake, is a right-lateral strike-slip fault trending northwest–southeast, and parallel to other major right-lateral faults in California. The fault spans about 46 miles onshore from Culver City to Newport Beach, where it enters the Pacific Ocean. This fault is expected to produce an earthquake of magnitude 7.4.<ref>{{Cite web|title=The 1933 Long Beach Earthquake|url=https://www.conservation.ca.gov/cgs/earthquakes/long-beach|access-date=2021-11-09|website=conservation.ca.gov}}</ref> The 1933 Long Beach earthquake was only a magnitude of about 6.4, approximately ten times less vibration amplitude and 1,000 times less energy release than that of a magnitude of 7.4 earthquake.{{Citation needed|date=March 2022}}

The earthquake plays a significant part in the novel ''[[The Last Tycoon]]'' (1941) by [[F. Scott Fitzgerald]]. During the disruption caused by the quake, the hero, Monroe Stahr, meets Kathleen Moore, with whom he falls in love.

The earthquake is also included in [[John Fante]]'s ''[[Ask the Dust]]'' (1939), and the earthquake scene in the novel is subject of a public art installation in [[Pershing Square (Los Angeles)|Pershing Square]] called "Hey Day" by [[Barbara McCarren]].

Footage of the earthquake appeared in the film ''Encounter with Disaster'', released in 1979 and produced by [[Sunn Classic Pictures|Sun Classic Pictures]].
