This view looks east: click for larger version. Label all structural features STOP #2: LO second floor GEOLOGY hallway Southern California Earthquake Map Synopsis General: The 1,100-km-long San Andreas fault zone is the principal element of the San Andreas fault system, a network of faults with predominantly dextral strike-slip displacement that collectively accommodates the majority of relative N-S motion between the North American and Pacific plates. A Garlock rupture could cause a San Andreas quake. San Francisco, Sacramento and the Sierra Nevada are on the North American Plate. The Garlock Fault runs southwest-northeast, forming the Tehachapi Mountain Range, establishing the Mojave Desert’s northern boundary along its western most point. The faults shown here are represented by simple lines which do not show how deep and large they really are. San Diego, Los Angeles and Big Sur are on the Pacific Plate. Map via Oregon State University. The researchers calculated if the Garlock fault was to rupture within 30 miles of its junction with the San Andreas Fault, it could “raise the probability of a San Andreas … The Big Pine fault is considered the western segment of the Garlock fault as offset by the San Andreas. The San Andreas fault (red) appears in the southwest corner of the map. Discover the beauty hidden in the maps. The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. And despite San Franciscos legendary 1906 earthquake, the San Andreas Fault does not go through the city. 5. Red circle is the Eastern California Shear Zone. Precipitation in the surrounding mountain ranges contributes to groundwater recharge. Those cores, pulled from canyons on the ocean floor, show evidence of earthquakes in the form of underwater landslides. Seventy miles north of downtown Los Angeles, the Tejon Summit is 4,160 feet above sea level. This fault is featured on the following maps: Northwest Fault Map Basin and Range Fault Map Mojave Fault Map Los Angeles Fault Map Find: San Andreas Fault Garlock Fault SKETCH Here: San Gabriel Mountains Santa Susana Mountains San Jacinto Fault Salton Sea CSUN Draw a sketch of this map with these fault, mountain locations, and CSUN. McGill’s former graduate student and a current department lecturer, Bryan Castillo, led an excavation of a section of the San Andreas Fault near Palm Springs, where he documented eight prehistoric earthquakes—while another recent graduate student, Kyle Pena, did the same on a section of the Garlock Fault. And the view west here: click for larger version. Menu Contact Search The San Andreas fault system is the major geologic boundary between the North American and Pacific tectonic plates and It slices California in two from Cape Mendocino to the Mexican border. The Ridgecrest ruptures ended just a few miles shy of the Garlock Fault, a major east-west fault running more than 185 miles (300 kilometers) from the San Andreas Fault to Death Valley. A new study suggests that last year’s Ridgecrest earthquakes increased the chance of a large earthquake on California’s San Andreas fault.. The probability of a big earthquake happening where the Garlock connects to it all the way down to, like, Palm Springs is … Get Free Fault Lines to the south and the faults of the Sierra Nevada are to the east. The San Andreas fault system is to the west, the Garlock fault is to the south and the faults of the Sierra Page 12/20. Scientists found that it has slipped 0.8 inch (or about 2 centimeters) near its surface since July. At the meeting of Garlock Fault and the San Andreas Fault is Tejon Summit. Map showing the Coso Geothermal Field to the north. The fault runs 185 miles east to west from the San Andreas Fault to Death Valley. See the answer. This page shows the location of San Andreas Fault, California 95459, USA on a detailed satellite map. The San Andreas Fault and many other Northern California fault zones are running north-south: Rodgers Creek fault zone, Maacama fault zone, Alexander-Redwood Hill fault , Hunting Creek-Berryessa fault zone, and West Napa fault zone. What Is The Orientation Of The San Andreas Fault System In Map View (looking Down On The Surface Of The Earth)? This map was created by a user. This problem has been solved! The valley, north of the San Gabriel Mountains (Angeles National Forest, San Andreas Fault) and south of the Garlock fault and the Tehachapi Mountains, this desert ecosystem spans approximately 2,200 square miles (5,698 km2). The new results stem from the analysis of sediment cores from the Mendocino Triple Junction area. Get free map for your website. State of California. The Cascadia Subduction Zone and the San Andreas Fault meet at the Mendocino Triple Junction. Blue arrows are the Garlock fault. San Andreas Fault crossing location of I-5 at Gorman, CA. Read Book Fault Lines Nevada are to the east. National Geographic, Esri, Garmin, HERE, UNEP-WCMC, USGS, NASA, ESA, METI, NRCAN, GEBCO, NOAA, increment P Corp. | The San Andreas Fault is the sliding boundary between the Pacific Plate and the North American Plate. Learn how to create your own. Two large mountain ranges are visible, the San Gabriel Mountains on the left and the Tehachapi Mountains in the upper right. That said, the San Andreas is such a high-risk fault anyway. Another fault, the Garlock Fault lies at the base of the Tehachapis; the San Andreas and the Garlock Faults meet in the center distance near the town of Gorman. The San Andreas fault system is to the west, the Garlock fault is Page 5/9. San Andreas Fault Zone. The cities of Desert Hot Springs, San Bernardino, Wrightwood, Palmdale, Gorman, Frazier Park, Daly City, Point Reyes Station and Bodega Bay rest on the San Andreas fault line. But co… From street and road map to high-resolution satellite imagery of San Andreas Fault. Seismologists took less than 24 hours after the July 5 quake to report that the formerly unknown strike-slip fault in Searles Valley, the epicenter of the 7.1 event north of Ridgecrest, appears to be now activating faults adjacent to the Garlock fissure, which intersects at a 90-degree angle with the San Andreas fault… A. Northeast-southwest B. The San Andreas generally follows the valley on the south side of Tejon Pass. Maphill is more than just a map gallery. In particular, those small faults in the Mojave appear to lead right up to the Garlock Fault, a 185-mile long fault line that connects Death Valley to the San Andreas. The Garlock Fault … San Andreas fault line map The San Andreas runs deep near and under some of California’s most populated areas. The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). The third and final place the fault crosses I-5 is just south of Gorman. Skip to Main Content. Red arrow is the San Andreas fault. Faults identified with green, brown or black lines are thought to be less active than those shown in orange and red. The reason, he explains, is that two quakes put new stresses on the Garlock fault, a relatively dormant fault that runs through the desert toward the San Andreas. If a Garlock Fault ruptured to within about 30 miles (45 kilometers) of its junction with the San Andreas Fault, we calculate it would raise the probability of a San Andreas rupture extending to the southeast, on the so-called ‘Mojave section,’ by factor of about 150. The northeast-striking Garlock fault (orange) runs south of Ridgecrest through the center of the map. California's Garlock fault line, was jostled into moving for the first time on record. East-west C. Southwest-northeast D. Northwest-southeast E. West-east . [1] Angeles National Forest The blue circle is where the earthquakes were. The San Andreas Fault Zone is more than one fault line, it's a zone. From space, the San Andreas Fault and its attending landforms are beautifully revealed. The Big Pine left lateral fault extends northeastward from Big Pine Mountain to the right lateral San Andreas fault, while the left lateral Garlock fault extends northeast from the San Andreas, but from a point 5 miles to the southeast. References. Choose from several map styles. Both the Mule Spring fault and the Leach Lake fault show evidence of surface rupture within the Holocene, so they probably accomodate a sizable fraction of the total slip of the western Garlock fault zone.
