AP The data collected and knowledge gained will help scientists identify which faults broke during the earthquake, determine the extent of faulting and surface displacement, and locate areas of ground failure to better understand the earthquake and its aftershocks. The number of aftershocks will drop off over time, but a large aftershock can increase the numbers again, temporarily. See the aftershock forecast for details. 5 M5+ earthquakes so far large enough to do damage. Public domain.). 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. Additional monitoring equipment will continue to be deployed to learn about this large earthquake. Circles indicate where scientists have visited the fault surface rupture. The City of Los Angeles has been a significant USGS partner in developing the ShakeAlert System in southern California. These locally installed instruments provide more precise measurements of small aftershocks, ground shaking, and ground deformation than more remote regional instruments can. The earthquakes were large enough that the fault rupture reached the earth’s surface. The 7.1-magnitude earthquake took place at 03:19 UTC on July 6, 2019 (8:19 p.m. Pacific Daylight Time on July 5; translate UTC to your time ).

Displacement at this location is primarily normal (vertical). Large aftershocks are still possible. The fact that I experienced that longass earthquake while on the toilet at the gym…and immediately blamed the celery juice, is about right. Within 14 seconds, the system increased its estimated magnitude to 6.3. Shaking from the earthquake was felt by millions of people across the region, including the greater Los Angeles and Las Vegas areas. Rarely is the surface rupture for large earthquakes expressed as a single, clear break, and in this case the rupture along part of its length is unusually broadly distributed. The magnitude 6.4 event ruptured along the NE-SW trending fault, and the subsequent magnitude 7.1 event ruptured along the NW-SE trending fault (USGS Public domain). AFTERSHOCK FORECAST* Be ready for more earthquakes. This research will help scientists understand the earthquakes, which faults broke during the earthquake, and the extent of faulting and surface displacement. That gave way 36 … Center line has been offset up and to the right as one looks across the fault towards the east. The Coso field itself is having very little aftershock activity. The ShakeAlertLA app was not activated because, as with the earlier magnitude 6.4 earthquake, ShakeAlert estimated no damage in Los Angeles County, the area covered by the app. Ruptures from the magnitude 6.4 event trend northeast to southwest, and ruptures from the magnitude 7.1 event trend northwest to southeast. The USGS calculates this earthquake forecast using a statistical analysis based on past earthquakes. The California Integrated Seismic Network, a network of about 400 high-quality ground motion sensors, enabled the USGS to produce a map of regional ground shaking shortly after the magnitude 7.1 event.
