The great Fort Tejon earthquake of 1857, with a ~350km long surface rupture, was the most recent major earthquake along the south-central San Andreas Fault (SAF). The earthquake left a surface rupture scar over 350 kilometers in length along the San Andreas fault. Of eight trees sampled, five showed damage or growth anomalies attributable to the 1857 event. We use a new approached to the topic: the research skills of a historian in collaboration with a geologist to generate quantitative data on the nature and location of ground shaking associated with the earthquake. The earthquake is probably the southern California Earthquake of 1857, sometimes called the Fort Tejon Earthquake. The 1857 Fort Tejon earthquake was one of the greatest earthquakes ever recorded in the U.S. (Magnitude was about Mw 8.0). The moment magnitude ( M w) 7.9 Fort Tejon earthquake of 1857, with a ~350-kilometer-long surface rupture, was the most recent major earthquake along the south-central San Andreas Fault, California.

The earthquake occurred on Friday morning, the 9th instant, at about the same time that it … It ruptured a distance of more than 300 kilometers from near Parkfield to Wrightwood. It ruptured the southern part of the San Andreas Fault for a length of about 225 miles (350 kilometers), between Parkfield and Wrightwood. The Fort Tejon earthquake occurred at about 8:20 am (Pacific time) on January 9, 1857 in central and Southern California with an estimated moment magnitude of 7.9. We investigated if seismicity patterns following 1857 could be due to static stress changes generated by the 1857 earthquake. Fort Tejon "The main disturbing force of the shocks which were so widely felt on the 9th, without doubt, was in the vicinity of the Fort [Fort Tejon], and extended to an unknown distance in the Desert. We examined significant departures from normal growth trends and interpreted them in light of the 1857 earthquake and other possible environmental factors. The Fort Tejon earthquake occurred at about 8:20 AM (Pacific time) on January 9, 1857. It ruptured a 360 kilometer (220 mile) segment of the San Andreas Fault and produced 10.0 meters (33 feet) of offset in this area. In comparison to the other "great" earthquakes of historic times, the 1857 "Fort Tejon" earthquake was larger than the 1872 Owens Valley (estimated magnitude 7.8) quake, and was equally as large as, if not larger than, the 1906 "San Francisco" earthquake (estimated magnitude 7.9-8.0). It ruptured the San Andreas Fault for a length of about 350 kilometers (220 mi), between Parkfield and San Bernardino. The Jan. 9, 1857, Fort Tejon earthquake in southern California, an estimated magnitude 7.9, offset stream channels by as much as 29 feet (9 m). When an express rider from Fort Tejon arrived in Stockton on January 15, he brought additional news of the quake’s effects in the vicinity of his post. 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 earthquake became associated with the fort by name because the area near the epicenter was sparsely populated. The Fort Tejon earthquake of 1857 was one of the greatest earthquakes ever recorded in the U.S., and left an amazing surface rupture scar over 350 kilometers in length along the San Andreas fault. share: RoofMonkey. Despite the immense scale of this quake, only two people were reported killed by the effects of the shock. The Fort Tejon earthquake occurred at about 8:20 am (Pacific time) on January 9, 1857 in central and Southern California with an estimated moment magnitude of 7.9. join. 48, No. The 1857 Fort Tejon earthquake is the largest historically recorded earthquake in southern California. This earthquake has killed only two people, but its magnitude has reached 7.9 MSK. ; 3rd March » Second Opium War: France and the United Kingdom declare war on China. 1857 Fort Tejon earthquake page: 1. Fifty one years before the Great San Fransisco Earthquake (Mag 7.7 - 7.8), there was the Fort Tejon quake, Mag ~7.9. 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.

The great earthquake of 1857, which became known as the Fort Tejon earthquake, was centered nearly 100 miles away. The great Fort Tejon earthquake of 1857, with an ~350-km-long surface rupture, was the most recent major earthquake along the south-central San Andreas fault (SAF). 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 1857 Ft. Tejon Earthquake: In Brief . Based on previous measurements of its surface slip distribution, rupture along the ~60-kilometer-long Carrizo segment was thought to control the recurrence of 1857-like earthquakes. The great Fort Tejon earthquake of 1857, with an ∼350‐km‐long surface rupture, was the most recent major earthquake along the south‐central San Andreas fault (SAF). Contemporary accounts indicate that the earthquake, lasting 1-3 min, was felt throughout most of California south of Sacramento [Agnew and Sieh, 1978]. There was a light, barely perceptible shock about six o’clock that morning, with a heavier one following at 8:30. Many people think that the 1906 San Francisco earthquake was the largest earthquake to strike California in historical times, but that distinction actually belongs to the shaker that rocked southern and central California on January 9, 1857, uprooting trees in the San Bernardino Mountains and causing the Kern River to flow backwards for a time. As a result, we are conducting an updated examination, with the hope of new insight regarding the 1857 Fort Tejon earthquake. In comparison to the other "great" earthquakes of historic times, the 1857 "Fort Tejon" earthquake was significantly larger than the 1872 Owens Valley (estimated magnitude 7.8) quake, and was equally as large as, if not larger than, the 1906 "San Francisco" earthquake (estimated magnitude 7.9-8.0). The great Fort Tejon earthquake of January 9, 1857 (magnitude 7.8) was the last major earthquake in this region. 195 This article focuses on how the 1857 earthquake was described pri-marily in contemporary newspapers, letters, and other periodicals and Historical Events for the Year 1857. The earthquake was felt as far north as San Jose, San Francisco, and Sacramento. The San Jacinto fault is shown as the dashed line, and the southern tip of rupture from the 1857 Fort Tejon earthquake is shown as the solid line in the upper left comer. Troops manning the fort were drawn away with the outbreak of the Civil War in 1861, and the fort was abandoned by 1864. 0. log in. The most reliable report of the event was issued from the fort, nearly 93 miles (149.7 km) distant. 2, 2013 ©2013 by the University of Texas Press DOI: 1 0.7560/IC48202. The Fort Tejon earthquake of January 9, 1857, was pro- duced by 3-10 m of right-lateral slip along at least 360 km of the San Andreas fault [Sieh, 1978b]. Annual ring widths were measured and plotted against the growth year determined by ring counting. In November 1857, the fort would become the headquarters of the army’s Camel Corps. All authorities agree this was one of the biggest quakes within California's recorded history, and at least one expert thought it was the biggest, even larger than the massive event that wrecked San Francisco in 1906. The Great 1857 "Fort Tejon" Earthquake, via WWW, July 12, 2005 (largest earthquake to hit Southern California in historic times occurred on January 9th, 1857, and it came to be known as the great "Fort Tejon" earthquake. Fort Tejon had been founded in 1854 just north of where the town of Lebec is today. 1857 Fort Tejon Earthquake The few reports by those who felt the February 2, 1881 shock indicates that this earthquake had intensity similar to those reported from more recent Parkfield main shocks. As a result of the shaking, the current of the Kern River was turned upstream, and water ran four feet deep over its banks. The Fort Tejon earthquake occurred at about 8:20 AM (Pacific time) on January 9, 1857.
