Mario Tama/Getty Images [111] Most notable of these earthquakes is the 1872 Owens Valley earthquake, With an estimated magnitude of 7.4 Mw (preferred; other estimates range as high as 7.9[112]), this earthquake is believed to be the greatest earthquake on record not only for California, but for all of the western United States. [96], East of Rose Valley, between the nearly parallel ends of the Owens Valley and Little Lake faults, lies the Coso Range and Coso Volcanic Field (a notable geothermal field). Power and water service was restored to Ridgecrest and roads were deemed safe by July 7; however, residents were advised to boil water for several days. The 7.1-magnitude temblor on July 6 was the most powerful earthquake in nearly 20 years in the Golden State. The sequence shook most of Southern California, the strongest quake happening about 190 km (120 miles) north of Los Angeles near Ridgecrest. Jones also noted that the magnitude of additional shocks would also likely increase, with some possibly exceeding 5 Mw . Relatively minor damage resulted from the initial foreshock, though some building fires were reported in Ridgecrest near the epicenter. [89], The ECSZ extends north along the east front of the Sierra Nevada Mountains to Walker Lane, a zone of faulting extending into Nevada and northward, where the Sierra Nevada (Sierran) microplate that underlies most of Central California is being torn away from North American continent. [20] Focused at a relatively shallow depth of 6.6 mi (10.7 km), the foreshock affected a large region populated by 20 million people. [17] The foreshock originated along a strike-slip fault in the Eastern California Shear Zone, a region frequented by earthquake swarms, near the edge of Death Valley National Park. Geological Survey, Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data. Rockslides covered multiple roads around the community, blocking off mountain roads, including the section of State Route 178 that connects Bakersfield with Lake Isabella. The number of aftershocks will drop off over time, but a large aftershock can increase the … @Cal_OES has been fully activated since this morning & is working closely with state & local emergency managers to respond to impacts to residents & infrastructure", "Cal OES Activates SOC in Support of Ridgecrest Earthquake in Southern California", "Earthquake Rattles Southern California; No Injuries Reported", "Strongest earthquake in years rattles Southern California; damage reported", "Disneyland Rides Close for Inspection After 6.4 Earthquake Jolts Southern California, Staff Say", "Nearly 11% chance of another earthquake of magnitude 7 or greater in Southern California, scientists say", "Californians' Alert Apps Didn't Sound for 2 Big Earthquakes. Photos of cracks forming in roadways between Trona and Ridgecrest, where at 6.4 magnitude earthquake struck Thursday, July 4, 2019. In the Ridgecrest area these include a ML5.2[121] earthquake in October 1961 near Brown (approximately halfway between Ridgecrest and Little Lake) that was felt in Independence and Los Angeles; it was preceded by eight minutes by an ML 3.4 foreshock felt in China Lake (east of Ridgecrest). At 10:33 a.m. Pacific Daylight Time (PDT) on July 4, 2019, an earthquake struck northeast of Ridgecrest, California, which is north of Los Angeles and northeast of Bakersfield. 2019 Ridgecrest Earthquake Sequence July 4, 2019–July 16, 2019. 2019-07-06 03:19:53 (UTC) 35.770°N 117.599°W; 8.0 km depth; Finite Fault View all finite-fault products (1 total) Catalog Magnitude Maximum Slip Source check US 7.0 Mw 2.5 m US 7 . Buildings in Los Angeles shook during the 2019 magnitude-7.1 Ridgecrest earthquake. They included three initial main shocks of Mw magnitudes 6.4, 5.4, and 7.1, and many perceptible aftershocks, mainly within the area of the Naval Air Weapons Station China Lake. While the actual shaking reached intensity 4 in some areas in the northern part of the county, in other parts the intensity reached only a level 2 or 3, not noticed by many people. [66], One person died in Pahrump, Nevada, when a lifted Jeep he was working under collapsed. [19] The exact fault it occurred on is uncertain with many small faults encompassing the region, though United States Geological Survey (USGS) seismologist Susan Hough stated it may have been the Little Lake Fault. The Earthquake Event Page application supports most recent browsers, view supported browsers. Due to temperatures exceeding 100 °F (38 °C), Cal OES established cooling stations in the affected areas. The NW-SE fault is believed to now have increased to between 25 and 30 miles in length. On 4 to 5 July 2019, the moment magnitude (Mw) 6.4 and Mw 7.1 Ridgecrest earthquake sequence ruptured a geometrically complex system of conjugate faults … Grayscale. M 7.1 - 2019 Ridgecrest Earthquake Sequence. [122] Additional earthquakes struck near Walker Pass in 1961 (ML 5.3),[123] 1962 (ML 4.9),[124] and 1979 (ML 4.3). Shakemap PGV Contours. [23], A significant series of additional earthquakes followed the foreshock, with the majority of magnitudes ranging approximately 2–4 Mw . Though the epicenter was nearly 124 miles (200 kilometers) away, shaking was felt throughout … Contact information: traditionnelmusette@gmail.com [Author]: … Shakemap MMI Contours. [106], Smaller earthquakes are quite common. [113], In March 1946 an ML 6.3[114] earthquake struck near Walker Pass (crest of the Sierra Nevada, due west from Ridgecest), with aftershocks continuing for nearly a year. On Thursday, July 4th, at 10:33 a.m. PST a magnitude 6.4 earthquake struck about 12 kilometers (10.5 miles) southwest of Searles Valley. Shakemap PSA03 Contours. This sequence was similar to the 2019 earthquakes in having two main shocks: an ML 5.4 earthquake on August 17 located 11 miles north of Ridgecrest,[129] and an ML 5.8 earthquake on September 20, located about a mile south-southwest of the first earthquake. According to our forecast, over the next 1 Year there is a < 1 % chance of one or more aftershocks that are larger than magnitude 7.1. [62] Emergency personnel responded to nearly two dozen incidents in the city and opened two shelters. Such an earthquake is possible, but with low probability. Over the past 40 years, prior to the July 4th event, 8 other M5+ earthquakes have occurred within 50 km of the July 6th, 2019 earthquake. [10] Subsequent aftershocks extended approximately 50 km (~30 miles) along the Little Lake Fault Zone. Businesses experienced product loss, with goods falling off shelves. [75], The State Operations Center for the California Governor's Office of Emergency Services (Cal OES) was raised to its highest level by Governor Newsom to coordinate resources. When that system detects an earthquake of magnitude 5.0 or greater it calculates the intensity of shaking to be expected in Los Angeles County, factoring in the calculated magnitude and distance of the source. They included three initial main shocks of Mw magnitudes 6.4, 5.4, and 7.1,[7] and many perceptible aftershocks, mainly within the area of the Naval Air Weapons Station China Lake. M 7.1 - 2019 Ridgecrest Earthquake Sequence. The ECSZ was originally limited to the area south of the Garlock Fault, which separates distinctly different modes of deformation, but now is considered to extend into Walker Lane. Taken earlier in the morning July 6, 2019 after the M7.1 earthquake which struck eastern California, southwest of Searles Valley, near Ridgecrest, CA. [95] The fault continues on to the Garlock Fault about 15 miles southeast of Ridgecrest, just past Searles Station. [11] Roughly 50 homes were damaged in the town. [9] This quake was preceded by several smaller earthquakes, and was followed by more than 1,400 detected aftershocks. All three earthquakes have been described by the United States Geological Survey as occurring via shallow strike-slip mechanisms. [16] The most populated area near the epicenter was Ridgecrest, home to 28,000 people. [118], At the southern end of the ECSZ the 1992 Landers earthquake, at magnitude Mw 7.2 (Ms7.8)[119] was also the strongest earthquake in California since 1906. It has again returned to the initial report of 7.1. M7+ is <1%1 in 300 chance. [11][10] Effects were felt across much of Southern California, parts of Arizona and Nevada,[12] as far north as the San Francisco Bay Area and Sacramento, and as far south as Baja California, Mexico. M7.1 18km W of Searles Valley, CA 2019-07-06 03:19:53 (UTC) 42,000+ responses via Did You Feel It? The OVF runs south, largely along U.S. Highway 395, through Bishop, Big Pine, Independence, and Lone Pine to the northern end of Rose Valley and the northwestern corner of the Naval Weapons Center (NWC), where the OVF turns slightly to the east. Scientists had no idea the fault that caused a 7.1 magnitude earthquake in Ridgcrest, California, existed until the area was rocked by the quake on July 5. @GavinNewsom has approved an emergency proclamation for the 6.4 magnitude earthquake in Kern County & aftershocks. "[107] How to explain this apparent lack of fault offsetting, and the larger question of how strain (dislocation) is transferred through or around the Garlock Fault, remains unanswered. [128] The Ridgecrest earthquake sequence of 1995 was particularly notable, having eight events M ≥ 4.0. 2019-07-06 03:19:53 (UTC) 35.770°N 117.599°W; 8.0 km depth; Moment Tensor View all moment-tensor products (3 total) Catalog Tensor Magnitude Depth % DC Source check CI 6.9 TMTS 8.0 km 97 % CI 5 US 7.1 Mww 11.5 km 94 % US 7 US 6.9 Mwb 17.0 km 92 % US 7 . [100] South of Little Lake the SNFF continues south along the west side of Indian Wells Valley (where Ridgecrest is situated), then curves west (roughly along California Highway 14) before connecting with the Garlock Fault. California Governor's Office of Emergency Services, "1st Fatality in Ridgecrest Earthquake May Be Man Found Dead Under Jeep 100 Miles From Epicenter: Investigators", "Ridgecrest Quake Damage Estimated Above $5 Billion at Massive China Lake Naval Base", "7.1-Magnitude Earthquake Hits Southern California; Experts Say More Strong Aftershocks Possible", "Second, stronger quake in Ridgecrest shakes Southern California, causing more damage", "Northern Ireland pair shaken by quake on 30th floor of Las Vegas hotel", "California shakes from 2nd big quake in 2 days", "Earthquake: 4.2 quake hits near Ridgecrest", "Strong earthquake sets off fires, damages desert city east of Los Angeles", "Magnitude 6.4 Earthquake Rocks Southern California on 4th of July", "Major 6.4 quake hits Mojave Desert, felt in Los Angeles, Las Vegas", "M 6.4 - 12km SW of Searles Valley, CA: Did You Feel It?

[74] Routine protocol inspections of major infrastructure, including the Los Angeles Aqueduct, were conducted across the Los Angeles metropolitan area. Water was also in high demand. [69], Following the shock, (NAWS) Naval Air Weapons Station China Lake evacuated all non essential personnel and declared the base as "not mission capable until further notice" in a statement published on the base's Facebook page on July 6. Ridgecrest has had: (M1.5 or greater) 13 earthquakes in the past 24 hours 31 earthquakes in the past 7 days; 92 earthquakes in the past 30 days; 1,983 earthquakes in the past 365 days The ground is displaced by 8 feet along the fault that ruptured in the magnitude 7.1 Ridgecrest earthquake of July 5, 2019. [84] The second quake, having a greater magnitude, was felt more strongly, with an intensity of 4.5 in some places, and 3.9 downtown. "This ended up being one of the best-documented earthquake sequences in history," lead … The 2019 Ridgecrest earthquakes (more commonly referred to in scientific literature as the 2019 Ridgecrest earthquake sequence) of July 4 and 5 occurred north and northeast of the town of Ridgecrest, California and west of Searles Valley (approximately 200 km [122 mi] north-northeast of Los Angeles). [81] ShakeAlertLA is triggered by the ShakeAlert system being developed by the USGS that monitors earthquakes across Southern California. [101], The easterly striking left-slip Garlock Fault south of Ridgecrest is one of California's longest active faults, and marks the boundary between different styles of tectonic deformation. [79], Many residents of Los Angeles County were not pleased when an earthquake early warning mobile app, ShakeAlertLA, did not alert them to either of the Ridgecrest earthquakes, which many people assumed to be failure. The surface trace of the Little Lake Fault is mapped through the northeast corner of the City of Ridgecrest, but due to the dip of the fault the epicenters of the 2019 earthquakes are mainly under the NWC, where the Little Lake Fault intersects the broad north-south oriented Airport Lake Fault Zone. [61][60] Some gas lines broke, prompting utility companies to shut off service. July 4–5, 2019, earthquakes in California. [82], At the time of the Ridgecrest earthquakes the threshold for issuing an alert was an expected shaking intensity in Los Angeles County of 4 (IV) on the Modified Mercalli Intensity Scale, what is considered "light shaking" with only slight damage (such as cracked plaster). [80] This app, developed by the City of Los Angeles in partnership with the USGS, and released at the beginning of 2019, is intended to give users located in Los Angeles County some tens of seconds of warning of possibly damaging shaking from a non-local earthquake. [17][21], At 8:19 p.m. PDT on July 5, a larger 7.1 Mw  earthquake occurred in the Ridgecrest area after being preceded by a 5.0 Mw  foreshock 3 minutes prior,[22] revealing the previous day's 6.4 Mw  earthquake to have been a foreshock. A minor earthquake magnitude 3 (ml/mb) has occurred on Monday, 8 kilometers (5 miles) from Ridgecrest in CA. [27] In Los Angeles proper, power outages affected the Fashion District and Granada Hills. 631 M3+ earthquakes so far strong enough to be felt, 5 M5+ earthquakes so far large enough to do damage. The magnitude 6.4 temblor turned out to be a foreshock of a stronger quake—magnitude 7.1—that occurred at 8:19 p.m. PDT on July 5 about 6 miles (11 kilometers) to the northwest. [60] The USGS sent geologists to Kern County soon after the foreshock to look for a surface rupture and collect data. This was certainly the case for the community of Ridgecrest, California, on July 4th, 2019, as they experienced a magnitude 6.4 earthquake. Some shook more than others. … M7.1 18km W of Searles Valley, CA2019-07-06 03:19:53 (UTC)42,000+ responses via Did You Feel It? RIDGECREST, Calif. — The second major Southern California earthquake in two days hit the area of Ridgecrest Friday night. Like, subscribe and comment below! The Ridgecrest earthquake sequence included a magnitude-6.4 foreshock on July 4, followed by a magnitude-7.1 mainshock nearly 34 hours later, and more than 100,000 aftershocks. An estimated 20 million people experienced the foreshock, and approximately 30 million people experienced the mainshock. [69] Newsom proclaimed a state of emergency for San Bernardino County on July 6. On the 4th of July 2019, the magnitude-6.4 Searles Valley earthquake rattled the region around Ridgecrest, California. [110], A large portion of the slippage between the Pacific and North American plates is accommodated in the Eastern California Shear Zone (ECSZ), resulting in many large earthquakes even within the limited span of the historical era. [72][73] Local emergency responders such as the Los Angeles Police Department used social media to alert the public that they were aware of the earthquake and to only use 9-1-1 if there was dangerous conditions or injuries. The July 5, 2019 magnitude 7.1 earthquake near eastern California’s Searles Valley resulted from shallow strike-slip faulting in the North America plate crust. These lie in a zone where stress and strike-slip movement from the OVF is transferred to various other faults to the south and east, including the Little Lake and Airport Lake faults. [77] The California National Guard deployed 200 personnel to assist in relief operations. [75] The Ventura County Fire Department dispatched personnel to survey the county for damage. Shakemap PGA Contours. [88] It is transected by the Garlock Fault, extending northeast and then east from the SAF's "Big Bend" to the Death Valley Fault near the Nevada state line, passing Ridgecrest about fifteen miles to the south. More than 50 earthquakes ranging in magnitude from 2.5 to 5.1 shook in the same remote area of Nevada over a 37-hour span Tuesday, Wednesday and … Credit: David Mark from Pixabay . A man inspects a crack in the earth after a 6.4-magnitude earthquake struck near Ridgecrest on July 4, 2019. [103] In particular, even though the Little Lake Fault is in general alignment with the Blackwater Fault[104] (and its southern extension, the Calico Fault), and a connection is "strongly suspected",[105] and though the aftershocks triggered along the entire length of these faults by the 1992 Landers earthquake suggests a structural continuity,[106] yet the surficial geology shows that "the Blackwater fault ends a few kilometers short of the Garlock fault. Thank you for watching US Military Moments. [86][87], The broad context of the Ridgecrest earthquakes is the Eastern California Shear Zone (ECSZ), a seismically active region east of the southern segment of the San Andreas Fault (SAF) and largely coincident with the Mojave Desert, featuring multiple right-lateral strike-slip faults paralleling the SAF. A magnitude 3.9 earthquake was reported at 11:26 a.m. Wednesday 12 miles from Ridgecrest, Calif., according to the U.S. Geological Survey. [130] Another shock on the 24th was ML 4.9. 3,557 earthquakes recorded since July 4, 2019 above Magnitude 2. The nature of the seismicity suggests an early stage in the formation of a strike-slip fault, before localized faulting in the shear zone has connected to form a continuous structure. The Ridgecrest earthquake sequence included a magnitude-6.4 foreshock on July 4, followed by a magnitude-7.1 mainshock nearly 34 hours later, and more than 100,000 aftershocks. [109], The Scodie Lineament is a zone of microseismicity extending southwest (paralleling the Garlock Fault) from near Walker Pass (due west of Ridgecrest) to align with the White Wolf Fault, scene of the 1952 Kern County earthquake south of Bakersfield. More distant earthquakes provide more warning, but are less damaging, than local earthquakes. [16][17] Residents near the epicenter reported that shaking lasted approximately 30 seconds. [65] Naval Air Weapons Station China Lake brought in additional personnel to conduct damage assessments. [75] Disneyland suspended ride operations for inspection. Magnitude 3 and above are large enough to be felt near the epicenter. [14][15] A foreshock registering 6.4 Mw  occurred at 10:33 a.m. PDT (17:33 UTC) 7.5 mi (12.1 km) southwest of Searles Valley. Residents of Ridgecrest, California, fled their homes, fearing buildings might collapse, after a magnitude-6.4 earthquake hit Southern California on Thursday. No additional damage occurred from any of the aftershocks. Why Not? [125] In 1977 two small quakes that hit Ridgecrest in February[126] were followed by another pair of small earthquakes in March. [115] The 1952 Kern County earthquake (Ms7.5, Mw 7.3[116]), considered the biggest earthquake to hit California since the 1906 San Francisco earthquake,[117] occurred on the White Wolf fault south of Bakersfield, and likely connected with the Walker Pass earthquake via the Scodie Lineament. The first main shock (now deemed to be a foreshock) occurred on July 4 at 10:33 a.m. PDT, approximately 18 km (11.2 mi) ENE of Ridgecrest, and 13 km (8.1 mi) WSW of Trona,[8] on a previously unnoticed NE-SW trending fault where it intersects the NW-SE trending Little Lake Fault Zone. [17] Fifteen patients at Ridgecrest Regional Hospital and residents in several apartment buildings were evacuated. [19] The number of aftershocks within hours of the earthquake were unusually high, but not unprecedented. Exact location of earthquake, -117.5868301° West, 35.609333° North, depth 5.73 km. [65][60] In Trona, several buildings sustained damage, water and gas lines broke, and power lines fell. [20] Shaking was felt as far north as Sacramento, California, eastward to Phoenix, Arizona, and as far south as Baja California, Mexico, with evacuations taking place in Mexicali and Tijuana. [28] Geologists at the USGS estimate an additional 34,000 aftershocks in the six months following the earthquakes.[29]. 3,557 earthquakes recorded since July 4, 2019 above Magnitude 2. [17][18] The rupture occurred along a 10 mi (16 km) section of an unspecified fault. Earth on either side of the fault was deformed, with lateral shifts of 6–8 in (15–20 cm) in the immediate vicinity. Structural damage and two building fires—one of which destroyed half of a home—occurred in Ridgecrest. [13], At 10:02 a.m. PDT (17:02 UTC) on July 4, 2019, a 4.0 Mw  foreshock occurred about 6.8 mi (10.9 km) southwest of Searles Valley, California. The Ridgecrest Earthquake Sequence started with a magnitude 6.4, followed by a magnitude 7.1 the next day with over 100 000 aftershocks. The United States Geological Survey initially reported it as a 7.1 magnitude earthquake at 8:19 p.m. with an updated magnitude of 6.9 immediately after. The first main … CHANCE OF AN EARTHQUAKE*in the next week until July 22, 2019. It is likely that there will be smaller earthquakes over the next 1 Year, with 21 to 46 magnitude 3 or higher aftershocks. At least 200 aftershocks of magnitude 2.5 or greater have been recorded after the earthquake through midday Friday, according to the US Geological Survey. Multiple aftershocks followed, and on Friday, July 5th, another earthquake struck with a magnitude of 7.1. The 2019 Ridgecrest earthquakes of July 4 and 5 occurred north and northeast of the town of Ridgecrest, California and west of Searles Valley. [78], In addition, Dr. Lucy Jones said that the odds of another 7 Mw  or above earthquake was a "1 in 10 chance", with a "50-50" chance of a 6 Mw  hitting the Owens Valley. A 4.9-magnitude earthquake was reported near Ridgecrest, California, on Friday morning -- one week after a 7.1-magnitude temblor struck Southern California, the US Geological Survey said. There has never been a 8.0 earthquake in California; the strongest on record is … [69] Multiple rockslides also occurred, making all roads to the city impassable. Street. Another similarity with the 2019 events: the first earthquake, although occurring on a north-northwest trending fault (presumably the Little Lake fault), may have involved a northeast-striking At 10:33 a.m. local time on 4 July 2019, a magnitude 6.4 earthquake struck California’s Mojave Desert near Ridgecrest (population 28,000). This is a list of earthquakes in 2019.Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for other reasons. The latter, now considered the mainshock, was the most powerful earthquake to occur in the state in 20 years (after the 1999 Hector Mine earthquake).

[108] This may indicate that the Garlock Fault is in the late stages of its earthquake cycle. On June 3, 2020, at 6:32 PM PST, a 5.5 Mw  aftershock was recorded 11 miles south of Searles Valley. [83] The intensity expected for Thursday's quake (on the 4th) was calculated to be less than that, so no alert was issued. [19] Around 20 injuries were reported, primarily from shattered glass and falling debris. [92], Along the eastern front of the Sierra Nevada strike-slip faulting happens on the Owens Valley Fault (OVF), part of which ruptured in the 1872 Owens Valley earthquake near Lone Pine.
