The northern branch of the fault zone in this area is known as the Mule Spring fault. Northwest Fault Map After about two decades with no major quakes, it’s a wakeup call that we need to be prepared. It is named after the historic mining town of Garlock , founded in 1894 by Eugene Garlock and now a ghost town . For well over 500 years the fault, running in an east-west direction for nearly 200 miles, has been silent. TYPE OF FAULTING: left-lateral strike-slip It is thought to have been triggered by the Landers earthquake, just two weeks earlier. 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. At least one fsection of the fault has shown movement by creep in recent years. These facts, along with the freshness of scarps left behind from previous ruptures and the on-going seismicity associated with the fault zone, leave little doubt that the Garlock fault zone will rupture again in the future. The July 4th earthquake would have affected the state of stress on nearby faults, including the east-west trending Garlock Fault, a major fault running along the south side of the epicentral area. The northern branch of the fault zone in this area is known as the Mule Spring fault. The most recent was a magnitude 5.7 near the town of Mojave on July 11, 1992. The most recent was a magnitude 5.7 near the town of Mojave on July 11, 1992. But since the Ridgecrest quakes, that major earthquake fault has begun to move. 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. The Garlock Fault Zone. The bulging of the Garlock fault line in California can be seen from space and it's moving in ways never seen before, raising the question for Californians if it raises the risk of "The Big One." SLIP RATE: between 2 and 11 mm/yr; probably averages about 7 mm per year The Garlock Fault runs from a junction with the San Andreas Fault in the Antelope Valley, eastward to a junction with the Death Valley Fault Zone in the eastern Mojave Desert. The above map shows fault zones in the Los Angeles Basin region. It forms the southern face of the El Paso Mountains, and last broke the surface in the Late Quaternary. Other Notes: The Garlock fault zone is one of the most obvious geologic features in southern California, clearly marking the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of … Garlock has been reported as capable of producing a magnitude 8 earthquake! The Garlock fault extends from the San Andreas Fault in the west to Death Valley in the east, and hasn’t had a major earthquake in about 500 years. near Tehachapi; 1500 A.D. These facts, along with the freshness of scarps left behind from previous ruptures and the on-going seismicity associated with the fault zone, leave little doubt that the Garlock fault zone will rupture again in the future. Los Angeles Fault Map, Southern California Earthquake Data Center, Training and Validation Data Sets for Deep Learning, magnitude 5.7 near the town of Mojave on July 11, 1992, Division of Geological and Planetary Sciences. The Walker Lane is a geologic trough roughly aligned with the California / Nevada border southward to where Death Valley intersects the Garlock Fault, a major left lateral, or sinistral, strike-slip fault. OTHER NOTES: The Garlock fault zone is one of the most obvious geologic features in southern California, clearly marking the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of the westernmost Basin and Range province. Los Angeles Fault Map, Southern California Earthquake Data Center, Training and Validation Data Sets for Deep Learning, magnitude 5.7 near the town of Mojave on July 11, 1992, Division of Geological and Planetary Sciences. It is thought to have been triggered by the Landers earthquake, just two weeks earlier. (?) The Garlock fault is an integral part of the plate-boundary deformation system inboard of the San Andreas fault (California, USA); however, the Garlock is transversely oriented and has the opposite sense of shear. The San Andreas fault system is the major geologic boundary between the North American and Pacific tectonic plates and passes through much of the state. The character of the Garlock fault has been a topic of contention among geologists since its discovery in 1910. “The Garlock fault is the border between the Sierras and the Mojave and all these different regions. SLIP RATE: between 2 and 11 mm/yr; probably averages about 7 mm per year The southern branch is known as the Leach Lake fault. The Garlock fault line is near the Ridgecrest area where earthquakes measuring M6.4 and M7.1 hit in July and were followed by thousands of aftershocks. The San Andreas fault system is to the west, the Garlock fault is to the south and the faults of the Sierra Nevada are to the east. About one-fifth the length of the San Andreas, the Garlock Fault runs along the Mojave Desert in Southern California. LENGTH: 250 km LENGTH: 250 km Geologic evidence demonstrates that the feature is not a tectonic fault or feature; this category includes features such as demonstrated joints or joint zones, landslides, erosional or fluvial scarps, or landforms resembling fault scarps, but of demonstrable non-tectonic origin. It forms the southern face of the El Paso Mountains, and last broke the surface in the Late Quaternary. The blue circle is where the earthquakes were. Of course, if you ask me, the San Madrid seismic zone remains the scariest in the nation, and one of the scariest in the world. near Johannesburg (Searles Valley) Aftershocks Propagating Towards the Garlock Fault Seismicity between the M=7.1 at 8:19pm and midnight (local) has continued to the northwest and southeast. The Garlock fault can cycle through long periods of hibernation, lasting as long as 3,000 years, Dolan said. Flying the drone over a portion of the Garlock Fault line, this is a pretty large fault, but not a particularly active one. Basin and Range Fault Map MOST RECENT SURFACE RUPTURES: 1050 A.D. It appears, led by the Garlock fault, that the state’s web of fault lines is in a state of chaos and disruption. While no earthquake has produced surface rupture on the Garlock fault in historic times (although cracks opened along a short segment of the fault in 1952, due to the shaking of the Kern County earthquake, and groundwater removal has also triggered slip in the Fremont Valley area), there have been a few sizable quakes recorded along the Garlock fault zone. It is named after the his­toric min­ing town of Gar­lock, founded in 1894 by Eu­gene Gar­lock and now a ghost town.

The Garlock fault runs along the northern border of the Mojave Desert in southern California. For the most up-to-date information, please refer to the interactive fault map. The 250 km long Garlock fault strikes roughly east-west and its current surface expression is located between the San Andreas fault and the Death Valley fault zone. The Garlock Fault nearby felt the pressure and has begun to move. It will create the biggest earthquakes—as big as magnitude 8—that will disrupt the whole region. Look just below the red Ridgecrest label on the map to see the Garlock Fault. Mojave Fault Map The bigger story could be other fault lines in the state erupting. Blue arrows are the Garlock fault. At least one fsection of the fault has shown movement by creep in recent years. 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. (?) Garlock Fault. While no earthquake has produced surface rupture on the Garlock fault in historic times (although cracks opened along a short segment of the fault in 1952, due to the shaking of the Kern County earthquake, and groundwater removal has also triggered slip in the Fremont Valley area), there have been a few sizable quakes recorded along the Garlock fault zone. Garlock Fault Zone. The Ridgecrest earthquakes shook Californians both physically and metaphorically. Little orange lines are the faults. The Garlock Fault is the defining fault between the Mojave Desert and Basin and Range geomorphic provinces. The fault also defines the boundary between the northwestern most Mojave and the southern portion of the Sierra Nevada geomorphic province. Here in Kern County there’s another fault even closer to Bakersfield, that has recently begun to move. OTHER NOTES: The Garlock fault zone is one of the most obvious geologic features in southern California, clearly marking the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of the westernmost Basin and Range province. This fault is featured on the following maps: As of January 12, 2017, the USGS maintains a limited number of metadata fields that characterize the Quaternary faults and folds of the United States. It marks the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of the westernmost Basin and Range province. The Owens Valley fault runs roughly northwest-southeast starting near the northern tip of the Ridgecrest fault, and it … The rupture from the second quake in … Instead, the Garlock fault underwent postseismic creep and exhibited a sizeable earthquake swarm. The research team estimates that there is a 2.3 percent chance of a magnitude 7.7 earthquake occurring on the Garlock fault in the next year, and a … Stretching for 250 kilometers (160 mi), it is the second-longest fault in California, and one of the most prominent geological features in the southern part of the state. The fault has slipped nearly an inch at its surface since the Ridgecrest quakes, scientists say. That’s going nowhere good.

California's Garlock fault line, was jostled into moving for the first time on record. near Tehachapi; 1500 A.D. The southern branch is known as the Leach Lake fault. The dynamic details of the rupture process during the mainshock are largely unknown, as is the amount of stress needed to bring the Garlock fault to failure. INTERVAL BETWEEN MAJOR RUPTURES: between 200 and 3000 years, depending on the fault segment TYPE OF FAULTING: left-lateral strike-slip NEAREST COMMUNITY: Frazier Park, Tehachapi, Mojave, Johannesburg The intersection of the San Andreas (the blue line) and Garlock (orange line) faults in southern California reflects two different tectonic forces: … The Gar­lock Fault runs from a junc­tion with the San An­dreas Fault in the An­te­lope Val­ley, east­ward to a junc­tion with the Death Val­ley Fault Zone in the east­ern Mo­jave Desert. The Garlock Fault in the Mojave desert was quiet for 500 years–but it's not looking so quiet any more News & City 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. But there are periods in which the Garlock fault is quite active. OTHER NOTES: The El Paso fault is a normal fault just north of the main trace of the Garlock fault near Koehn Lake. near Johannesburg (Searles Valley) References. The southern branch is known as the Leach Lake fault. Garlock fault zone, Western Garlock … The Garlock fault zone makes up the northern edge of the Mojave and for the first time since scientists have been gathering data on it, it’s begun to move. PROBABLE MAGNITUDES: MW6.8 - 7.6 The slip history of the Garlock is critical for interpreting the deformation of the through-going dextral shear of the Walker Lane belt–Eastern California shear zone. Basin and Range Fault Map Click on faults for more information. OTHER NOTES: At the eastern end of the Garlock fault zone, the main trace splits up. This fault is featured on the following maps: Northwest Fault Map But the central Garlock fault, despite being located immediately south of this sequence, did not coseismically fail. This fault is featured on the following maps: Northwest Fault Map Faults in LA County: San Andreas Fault Mojave Section Map Garlock Fault Map Sierra Madre Zone Fault Map Whittier Fault Map Malibu Area Fault Map Raymond Fault Map San Fernando Valley Fault Map Santa Monica Area Faults (?)
