The probability of a serious earthquake on various faults has been estimated in the 2008 Uniform California Earthquake Rupture Forecast. According to the United States Geological Survey, Southern California experiences nearly 10,000 earthquakes every year. [3] Details on specific faults can be found in the USGS Quaternary Fault and Fold Database.
The San Jacinto Fault Zone and the San Andreas Fault (SAF) accommodate up to 80% of the slip rate between the North American and Pacific plates.The extreme southern portion of the SAF has experienced two moderate events in historical times, while the SJFZ is one of California's most active fault zones and has repeatedly produced both moderate and large events.
A map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
The Imperial fault was the source of the 1940 El Centro earthquake and the 1979 Imperial Valley earthquake. There was more than 30 km (19 mi) of surface rupture associated with the 1979 event along the northwest trending Imperial fault from just north of the Mexico–United States border to an area south of Brawley and the BSZ was found to have ...
A magnitude 4.2 earthquake was felt widely across the nation's second largest city Friday and shook things off shelves near the epicenter in a small mountain community east of Los Angeles, but ...
The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
