Fort Tejon - 1857 Fort Tejon Earthquake

1857 Fort Tejon Earthquake

The Fort Tejon earthquake occurred at about 8:20 AM (Pacific time) on January 9, 1857. It ruptured the San Andreas Fault for a length of about 350 kilometers (220 mi), between Parkfield and San Bernardino. Displacement along the fault was as much as 9 meters (30 feet) in the Carrizo Plain but less along the Palmdale section of the fault, closest to Los Angeles. The amount of fault slip gives this earthquake a moment magnitude of 7.9, comparable to that of the 1906 San Francisco earthquake. Based on the (uncertain) distribution of foreshocks for this earthquake, it is assumed that the beginning of the fault rupture (the epicenter) was in the area between Parkfield and Cholame, about 60 miles northwest. Nevertheless, it is usually called the "Fort Tejon" earthquake because this was the location of the greatest damage, most of the area being unpopulated at the time.

Famous quotes containing the words fort and/or earthquake:

    “Across Parker Avenue from the fort is the Site of the Old Gallows, where 83 men “stood on nothin’, a-lookin’ up a rope.” The platform had a trap wide enought to “accommodate” 12 men, but half that number was the highest ever reached. On two occasions six miscreants were executed. There were several groups of five, some quartets and trios.”

    “It is crystal clear to me that if Arabs put down a draft resolution blaming Israel for the recent earthquake in Iran it would probably have a majority, the U.S. would veto it and Britain and France would abstain.”
    —Amos Oz (b. 1939)
