Photograph taken along the San Francisco peninsula after the 1906 Depuis le séisme de 1906, et après un demi-siècle de calme, l'activité a légèrement repris à partir de 1957. San Andreas fault in 1906. All rights reserved. Science Politique; Sécurité internationale & défense; Intelligence économique & The southwestward motion of the North American Plate towards the Pacific is creating compressional forces along the eastern side of the fault. De plus, même si le laboratoire de recherche en armement nucléaire est construit directement sur la faille de San Andreas, les autorités assurent que, grâce à une parfaite conformité aux normes parasismiques et à de fréquentes inspections, ce bâtiment peut résister à un séisme de très grande magnitude. In 1953, geologist Thomas Dibblee concluded that hundreds of miles of lateral movement could occur along the fault. In 2004, work began just north of Parkfield on the San Andreas Fault Observatory at Depth (SAFOD). Esprit RI. A project called the San Andreas Fault Observatory at Depth (SAFOD) near Parkfield, Monterey County, was drilled through the fault during 2004–2007 to collect material and make physical and chemical observations to better understand fault behavior.[3]. The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. The main southern section of the San Andreas Fault proper has only existed for about 5 million years. La Faille DE San Andreas USA, CALIFORNIE Une des faille la plus active sur le globe terreste Dans la photo que vous allez voir s'est Los Angeles detruit en 1906 ou se situe la faille ??? (In this region around the San Francisco Bay Area several significant "sister faults" run more-or-less parallel, and each of these can create significantly destructive earthquakes.) The San Andreas fault today has locked and creeping segments along its approximately 800 mile (1300 km) length in California. Photograph taken along the San Francisco peninsula after the 1906 earthquake showing fault trace offsetting a fence and tree line between Such a large earthquake on this southern segment would kill thousands of people in Los Angeles, San Bernardino, Riverside, and surrounding areas, and cause hundreds of billions of dollars in damage. La faille de San Andreas est une immense faille géologique de 1 300,4 km de long, située en Californie.Elle est située à la jonction des deux plaques tectoniques du Pacifique et de l'Amérique.. Cette faille est la cause de fréquents séismes parfois dévastateurs, comme celui qui détruisit la ville de San Francisco en 1906. Español:Esta imagen muestra la topografía de la región a partir de datos de la NASA Shuttle Radar Topography Mission. 1c, New Scripps Study Reveals San Andreas Fault Set for the 'Big One', "Scientists Search for a Pulse in Skies Above Earthquake Country", Thule Scientific Interactive Map of the San Andreas Fault, Rescue Lineament-Bear Mountains fault zone, https://en.wikipedia.org/w/index.php?title=San_Andreas_Fault&oldid=1004911220, Geography of Los Angeles County, California, Geography of San Bernardino County, California, Geography of San Mateo County, California, Geography of Santa Clara County, California, Geology of Los Angeles County, California, Geology of San Bernardino County, California, Articles with failed verification from July 2019, Short description is different from Wikidata, Articles needing additional references from December 2015, All articles needing additional references, Articles with failed verification from April 2019, Wikipedia articles with WORLDCATID identifiers, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 February 2021, at 01:25. in the archives of the Bancroft Library at the University of California, Development in many cases has obliterated the traces of the 1906 rupture, This idea, which was considered radical at the time, has since been vindicated by modern plate tectonics.[12]. The reason for this is not clear. According to this study, a massive earthquake on that southern section of the San Andreas fault would result in major damage to the Palm Springs–Indio metropolitan area and other cities in San Bernardino, Riverside and Imperial counties in California, and Mexicali Municipality in Baja California. These geological features are what are chiefly seen along San Andreas Fault. are also useful for determining the amount of 1906 offset and the width However the 1906 San Francisco earthquake seems to have been the exception to this correlation because the plate movement was moved mostly from south to north and it was not preceded by a major quake in the Cascadia zone.[20]. Francisco peninsula and in the [16] Icelandic Translation for faille de San Andreas - dict.cc English-Icelandic Dictionary. a very thorough and important scientific report, published in 1908 (A.C. The fault continues northwest alongside the Elizabeth Lake Road to the town of Elizabeth Lake. Or des séismes majeurs s'y … The Elkhorn Scarp defines the fault trace along much of its length within the plain. The photographs It eventually occurred in 2004. peninsula after the 1906 earthquake showing 2 distinct fault traces. [11] The first known incarnation of the southern part of the fault was Clemens Well-Fenner-San Francisquito fault zone around 22–13 Ma. Les sismologues avaient évalué qu’un tremblement de terre majeur se produisait à peu près tous les 80 ans. (Geography) fault. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. It is often described as having been named after San Andreas Lake, a small body of water that was formed in a valley between the two plates. into the 1906 rupture along the San Andreas, particularly along the San It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. [10] At this time, a spreading center between the Pacific Plate and the Farallon Plate (which is now mostly subducted, with remnants including the Juan de Fuca Plate, Rivera Plate, Cocos Plate, and the Nazca Plate) was beginning to reach the subduction zone off the western coast of North America. The numbers on the fault line indicate how far the ground surface slipped at that location as a result of the 1906 earthquake. Copyright © by HarperCollins Publishers. the scanned 1950 (817K) and 1980 Outre la faille de San Andreas, ce secteur se compose de plusieurs longues failles parallèles pouvant provoquer de violents séismes (notamment la faille de Hayward à l'est de la baie de San Francisco ). est une VILLE construite sur une QUARANTAINE de … Due to the frequency of predictable activity, Parkfield has become one of the most important areas in the world for large earthquake research. To get an impression of the extent of development in one area compare The San Andreas Fault is shifting. DEVISE de la VILLE" ORO en PAZ , FIERRO en GUERRA "est surnommée The CITY by the BAY. The San Andreas began to form in the mid Cenozoic about 30 Mya (million years ago). The San Andreas Fault runs in a northwest-southeast line along the coast. [7][8], Assuming the plate boundary does not change as hypothesized, projected motion indicates that the landmass west of the San Andreas Fault, including Los Angeles, will eventually slide past San Francisco, then continue northwestward toward the Aleutian Trench, over a period of perhaps twenty million years. Bancroft Library. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). [19], A 2008 paper, studying past earthquakes along the Pacific coastal zone, found a correlation in time between seismic events on the northern San Andreas Fault and the southern part of the Cascadia subduction zone (which stretches from Vancouver Island to northern California). Elle est placée sur la FAILLE DE SAN ANDREAS . As it passes the towns of Gorman, Tejon Pass and Frazier Park, the fault begins to bend northward, forming the "Big Bend". The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. Saved by ... San Andreas fault in 1906. En 1906, la faille provoqua un séisme de 8,3 sur l’échelle de Richter qui dévasta San Francisco. Eleven years later, Lawson discovered that the San Andreas Fault stretched southward into southern California after reviewing the effects of the 1906 San Francisco earthquake. [2] Following the 1906 San Francisco earthquake, Lawson concluded that the fault extended all the way into southern California. Loma Prieta area. are being used to map the fault more precisely than has been previously Le dernier gros tremblement de terre à avoir frappé la Californie remonte à 1906. Recent research in historical archives has provided important new insights The ability to predict major earthquakes with sufficient precision to warrant increased precautions has remained elusive. Linguee. Northwest of Frazier Park, the fault runs through the Carrizo Plain, a long, treeless plain where much of the fault is plainly visible. The fault was identified in 1895 by Professor Andrew Lawson of UC Berkeley, who discovered the northern zone. The effect is expressed as the Coast Ranges. the region around Los Angeles, because massive earthquakes have occurred relatively recently on the central (1857) and northern (1906) segments of the fault, while the southern section has not seen any similar rupture for at least 300 years. The San Andreas Fault has had some notable earthquakes in historic times: A continental transform fault through California between the Pacific Plate and the North American Plate, This article is about the continental fault in California. However, according to some of his reports from 1895 and 1908, Lawson actually named it after the surrounding San Andreas Valley. Jan 8, 2013 - San Andreas fault trail. It also includes a possible driver for the deformation of the Basin and Range, separation of the Baja California Peninsula, and rotation of the Transverse Range. At its closest, this fault passes about 35 miles (56 km) to the northeast of Los Angeles. [1] It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). A collection of about 600 glass plate negatives, many unpublished, is in the archives of the Bancroft Library at the University of California, Berkeley. la faille de San Andrea the San Andreas Fault. Older buildings would be especially prone to damage or collapse, as would buildings built on unconsolidated gravel or in coastal areas where water tables are high (and thus subject to soil liquefaction). Sur la faille de San Andreas, on estime le taux de retour des séismes majeurs à un tout les 200 ans. [17], The U.S. Geological Survey most recent forecast, known as UCERF3 (Uniform California Earthquake Rupture Forecast 3), released in November 2013, estimated that an earthquake of magnitude 6.7 M or greater (i.e. Photograph taken after the 1906 earthquake showing offset of road
