Little orange lines are the faults. The southern branch is known as the Leach Lake fault. But there are periods in which the Garlock fault is quite active. 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. 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. Northwest Fault Map 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." But the central Garlock fault, despite being located immediately south of this sequence, did not coseismically fail. Basin and Range Fault Map (?) KGET 17 | 01-09. The rupture from the second quake in … Basin and Range Fault Map The intersection of the San Andreas (the blue line) and Garlock (orange line) faults in southern California reflects two different tectonic forces: … MOST RECENT SURFACE RUPTURES: 1050 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. NEAREST COMMUNITY: Frazier Park, Tehachapi, Mojave, Johannesburg That’s going nowhere good. 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. Mojave Fault Map Here in Kern County there’s another fault even closer to Bakersfield, that has recently begun to move. It appears, led by the Garlock fault, that the state’s web of fault lines is in a state of chaos and disruption. Mojave Fault Map It is named after the his­toric min­ing town of Gar­lock, founded in 1894 by Eu­gene Gar­lock and now a ghost town. 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 northern branch of the fault zone in this area is known as the Mule Spring fault. The Owens Valley fault runs roughly northwest-southeast starting near the northern tip of the Ridgecrest fault, and it … 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. 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. 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. The character of the Garlock fault has been a topic of contention among geologists since its discovery in 1910. Instead, the Garlock fault underwent postseismic creep and exhibited a sizeable earthquake swarm. “The Garlock fault is the border between the Sierras and the Mojave and all these different regions. The Garlock Fault in the Mojave desert was quiet for 500 years–but it's not looking so quiet any more News & City MOST RECENT SURFACE RUPTURES: 1050 A.D. Click on faults for more information. near Johannesburg (Searles Valley) The northern branch of the fault zone in this area is known as the Mule Spring fault. 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. This fault is featured on the following maps: Flying the drone over a portion of the Garlock Fault line, this is a pretty large fault, but not a particularly active one. It forms the southern face of the El Paso Mountains, and last broke the surface in the Late Quaternary. 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.

The Garlock fault runs along the northern border of the Mojave Desert in southern California. At least one fsection of the fault has shown movement by creep in recent years. The bigger story could be other fault lines in the state erupting. 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.

References. near Johannesburg (Searles Valley) PROBABLE MAGNITUDES: MW6.8 - 7.6 It forms the southern face of the El Paso Mountains, and last broke the surface in the Late Quaternary. 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. This fault is featured on the following maps: Northwest Fault Map For the most up-to-date information, please refer to the interactive fault map. The southern branch is known as the Leach Lake fault. Garlock fault zone, Western Garlock … After about two decades with no major quakes, it’s a wakeup call that we need to be prepared. The blue circle is where the earthquakes were. 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. 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 is thought to have been triggered by the Landers earthquake, just two weeks earlier. LENGTH: 250 km The Garlock Fault is the defining fault between the Mojave Desert and Basin and Range geomorphic provinces. SLIP RATE: between 2 and 11 mm/yr; probably averages about 7 mm per year It will create the biggest earthquakes—as big as magnitude 8—that will disrupt the whole region. It is named after the historic mining town of Garlock , founded in 1894 by Eugene Garlock and now a ghost town . 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. Northwest Fault Map 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. 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. 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 San Andreas fault system is the major geologic boundary between the North American and Pacific tectonic plates and passes through much of the state. Garlock has been reported as capable of producing a magnitude 8 earthquake! The Ridgecrest aftershocks have also headed southeast toward the Garlock fault, a lesser-known fault capable of producing an earthquake of magnitude … The above map shows fault zones in the Los Angeles Basin region. 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 Garlock Fault Zone. TYPE OF FAULTING: left-lateral strike-slip 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. 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. About one-fifth the length of the San Andreas, the Garlock Fault runs along the Mojave Desert in Southern California. OTHER NOTES: The El Paso fault is a normal fault just north of the main trace of the Garlock fault near Koehn Lake. INTERVAL BETWEEN MAJOR RUPTURES: between 200 and 3000 years, depending on the fault segment But since the Ridgecrest quakes, that major earthquake fault has begun to move. 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. The Garlock Fault nearby felt the pressure and has begun to move. near Tehachapi; 1500 A.D. The southern branch is known as the Leach Lake fault. Look just below the red Ridgecrest label on the map to see the Garlock Fault. PROBABLE MAGNITUDES: MW6.8 - 7.6 OTHER NOTES: At the eastern end of the Garlock fault zone, the main trace splits up. This fault is featured on the following maps: (?) 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 Ridgecrest earthquakes shook Californians both physically and metaphorically. Garlock Fault. At least one fsection of the fault has shown movement by creep in recent years. 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. It is thought to have been triggered by the Landers earthquake, just two weeks earlier. SLIP RATE: between 2 and 11 mm/yr; probably averages about 7 mm per year 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. near Tehachapi; 1500 A.D. TYPE OF FAULTING: left-lateral strike-slip 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 … Red circle is the Eastern California Shear Zone. 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. For well over 500 years the fault, running in an east-west direction for nearly 200 miles, has been silent. 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. California's Garlock fault line, was jostled into moving for the first time on record. 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. OTHER NOTES: The El Paso fault is a normal fault just north of the main trace of the Garlock fault near Koehn Lake. 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. The Garlock fault can cycle through long periods of hibernation, lasting as long as 3,000 years, Dolan said. Garlock Fault Zone.

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. 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. The fault has slipped nearly an inch at its surface since the Ridgecrest quakes, scientists say. 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.
