The 1857 Fort Tejon earthquake occurred at about 8:20 a.m. (Pacific time) on January 9 in central and Southern California. One of the largest recorded earthquakes in the United States, [6] with an estimated moment magnitude of 7.9, it ruptured the southern part of the San Andreas Fault for a length of about 225 miles (350 km), between Parkfield ...

2019年8月5日 · About 20 kilometers west of Fort Tejon, trees were uprooted, and buildings were destroyed between Fort Tejon and Elizabeth Lake. One person was killed in the collapse of an adobe house at Gorman. Strong shaking lasted from 1 to 3 minutes.

The Fort Tejon earthquake of 1857 was one of the largest earthquakes ever recorded in California, and left an amazing surface rupture scar over 350 kilometers in length along the San Andreas fault.

Relatively little is known about the seismic activity near Parkfield at the time of the great Fort Tejon earthquake on January 9, 1857. What we do know is that several meters of sudden right-lateral slip on the San Andreas fault produced shaking that lasted 1 to 3 minutes and that was felt over more than 350,000 square kilometers of central and ...

2010年7月1日 · The two greatest quakes in the state’s history, the San Francisco and the Tejon quakes, took place along this fault. The Fort Tejon earthquake struck a little after 8:20 a.m. …

2021年1月16日 · The 7.9 magnitude Tejon Earthquake (with an intensity of perhaps 8.25), which struck about 8:20 am on the morning of Jan. 9, 1857 is considered by many to be the largest historic earthquake that California has witnessed, vying for that title with the better known San Francisco quake of 1906.

This earthquake occurred on the San Andreas fault, which ruptured from near Parkfield (in the Cholame Valley) almost to Wrightwood, a distance of about 300 km. Horizontal displacement of as much as 9 m was observed on the Carrizo Plain. It caused one fatality.

And the largest earthquake to hit Southern California in historic times occurred on January 9, 1857. It came to be known as the great "Fort Tejon" earthquake — although such appellation could be very misleading. Fort Tejon, in fact, was not the epicenter, nor was it even near the epicenter of the earthquake.

On January 9, 1857, California’s greatest ever earthquake struck the central part of the state near the San Andreas Fault. It left a surface scar of more than two hundred miles along the line of the fault and caused a horizontal displacement as large as thirty feet. Its magnitude was 7.9.

Because of the small population in the state in 1857 (perhaps 350,000 people), there were only two fatalities, one near Fort Tejon, where many buildings were destroyed. The earthquake was strongly felt from Los Angeles to San Francisco.
