What fault caused the 1994 Northridge earthquake?
thrust faults
The thrust faults along which the 1971, 1987, and 1994 earthquakes occurred are the result of a big bend in the San Andreas fault. The bend causes crumpling, or “compression” of the Earth’s crust nearby, giving rise to the thrust faults.
What freeway collapsed the Northridge earthquake?
Of the most striking images in the quake’s aftermath, the collapse of the Antelope Valley Freeway captured the sheer force of the seismic event. In the aftermath of the 1994 Northridge earthquake, many changes were implemented in preparation for future earthquakes.
What caused the 1971 San Fernando earthquake?
The San Fernando Fault is a thrust fault, which means a section of land above the fault moved up and over a region below it. The earthquake was a single episode of ongoing crustal deformation, which, in a local sense, has pushed the San Gabriel Mountains up and south towards the broader Los Angeles Basin.
What was the worst earthquake in California history?
California’s Largest Recorded Earthquakes Since 1800, Ranked by Magnitude

| 7.8 | April 18, 1906 | San Francisco |
| 7.4 | Mar. 26, 1872 | Owens Valley |
| 7.4 | Nov. 8, 1980 | W. of Eureka* |
Is it possible for California to fall into the ocean?
No, California is not going to fall into the ocean. California is firmly planted on the top of the earth’s crust in a location where it spans two tectonic plates.
Why was the Northridge Earthquake so destructive?
The Northridge earthquake produced extremely strong ground shaking, which caused the greatest damage in the United States since the 1906 San Francisco earthquake. The Northridge earthquake was caused by dip slip on a thrust fault—the overriding movement of one crustal block up and over a second crustal block (see p.
What city in California has the most earthquakes?
San Francisco has the highest risk of an earthquake as it is located directly on the San Andreas fault, one of the most volatile in the world. Because of its location relative to major fault lines, the Greater Bay Area experiences many earthquakes year-round.
