The 1971 San Fernando earthquake (also known as the 1971 Sylmar earthquake) occurred in the early morning of February 9 in the foothills of the San Gabriel Mountains in Southern California. The unanticipated thrust earthquake had a magnitude of 6.5 on the M s scale and 6.6 on the M w scale, and a maximum Mercalli intensity of XI ( Extreme ).
Between 1964 and 1994, Los Angeles faced two big earthquakes, which both hit the suburban San Fernando Valley hard: the magnitude 6.6 Sylmar earthquake of 1971, which resulted in 64 deaths; and ...
This is a list of earthquakes in 1971. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to ...
The collapse of the San Fernando Veterans Administration hospital, a non-ductile concrete building, in the 1971 Sylmar earthquake led to the deaths of 49 people.
This was the second time in 23 years the area had been affected by a strong earthquake. On February 9, 1971, the San Fernando earthquake (also known as the Sylmar earthquake) struck the area with a magnitude of 6.5.

Friday is the 53rd anniversary of Southern California's 1971 San Fernando earthquake, which was recorded as magnitude 6.6. Also known as the Sylmar earthquake, it killed 64 people and caused over ...
The large amount of slip observed there did not correspond with a short 15–20 km (9.3–12.4 mi) rupture length of the Sierra Madre Fault Zone, and instead suggested that the historical thrust earthquakes were much larger in magnitude than what was seen with the 1971 event, given its smaller 2 meters (6 ft 7 in) of maximum observed displacement.
