The USGS operates a 24/7 National Earthquake Information Center in Colorado that can be reached for more information at 30. The latest earthquakes on a map with news, lists, and links. If you felt this earthquake, report your experience on the “USGS Did You Feel It?” website for this event. The Wireless Emergency Alert system did not distribute alerts for the earthquake because the underestimation of the quake meant it did not reach the system's threshold of alerting for earthquakes that are M5.0 or stronger. Hellweg previously served as SSA Secretary and co-chaired the 100th Anniversary Earthquake Conference, SSA’s joint meeting. ![]() RECENT CALIFORNIA EARTHQUAKES ANDROIDApp providers, including MyShake, and QuakeAlertUSA, as well as Google Android have an alerting threshold of M4.5. The apps also sent alerts for a M4.6 aftershock at 23:33 UTC (4:33 pm local time) that was correctly located. Big California Earthquakes Below is a table of significant California earthquakes, sorted chronologically (most recent first). Peggy Hellweg, operations manager for the Berkeley Seismological Laboratory (BSL) at the University of California, Berkeley, was elected president-elect by the Board of the Seismological Society of America on 14 April. ShakeAlert Messages were distributed via app partners for the inaccurately located M4.8 (near Stockton) that occurred as shaking from the M6.0 travelled across the state. As the USGS builds more stations, it expects to see most of these issues resolved. The system is constantly growing and learning from events like these. This can cause issues like inaccurately locating and miscalculating the quake. The system initially thought it was detecting three different smaller earthquakes rather than one larger one. With relatively few seismic stations in this part of California, earthquake waves have to travel further to be detected. If you would like to see prior earthquakes, visit our interactive map HERE.

Quakes in the past 24 hours: In the past 24 hours, California had 1 quake of magnitude 3.0 and 8 quakes between 2.0 and 3.0. ![]() The ShakeAlert Earthquake Early Warning System detected the earthquake 25.6 seconds after it started, but under-estimated the magnitude as a M4.8 at an estimated location that was about 31 miles (50 km) south of the actual location. Below are earthquakes from the last 48 hours. The driving force of earthquakes in California is movement along the San Andreas Fault and the many associated faults within the San Andreas Fault System that. For estimates of casualties and damage, visit the USGS Prompt Assessment of Global Earthquakes for Response (PAGER) website. Visit the USGS earthquake event page for more information. The USGS is coordinating its response with the California Geological Survey and the University of Nevada at Reno. USGS scientists expect that this event will trigger aftershocks, but these will decrease in frequency over time. The event was widely felt, with over 25,000 "Did You Feel It?" reports thus far submitted. The quake is a result of normal faulting at approximately 6.2 miles (10 km) depth near the Antelope Valley fault, which runs north-south along the Sierra Nevada range front. The research finds that the 2019 Ridgecrest, California, quakes shifted underground stresses, making the San Andreas faultthe states longest and most dangerous faultthree. Perceived shaking for the quake was very strong. A pair of earthquakes that struck the remote California desert 1 year ago have raised the risk of 'the big one' hitting Southern California, according to a new study.
