The 1868 Hayward earthquake occurred in the San Francisco Bay Area, California, United States on October 21.With an estimated moment magnitude of 6.3–6.7 and a maximum Mercalli intensity of IX (Violent), it was the most recent large earthquake to occur on the Hayward Fault Zone.
The 1925 Santa Barbara earthquake hit the area of Santa Barbara, California on June 29, with a moment magnitude between 6.5 [1] and 6.8 [3] and a maximum Mercalli Intensity of IX (Violent). It resulted in 13 deaths and destroyed the historic center of the city, with damage estimated at $8 million (about $111 million in 2017).
The 1994 Northridge earthquake affected the Los Angeles area of California on January 17, 1994, at 04:30:55 PST. The epicenter of the moment magnitude 6.7 ( M w ) blind thrust earthquake was beneath the San Fernando Valley . [ 3 ]
The 1872 Owens Valley earthquake – also known as the Lone Pine earthquake – struck on March 26 at 02:30 local time in the Owens Valley (California, along the east side of the Sierra Nevada), with the epicenter near the town of Lone Pine. Its magnitude has been estimated at M w 7.4 to 7.9, with a maximum Mercalli Intensity of X (Extreme).
The United States Geological Survey says there have been at least 40 other earthquakes of a magnitude 6.0 or larger in the region during the last 100 years. 7.0 California Shake Intensity
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings – later followed by seismotomography imaging technique, [1] observations using space satellites from outer space, [2] artificial intelligence (AI)-based early earthquake warnings [3] – they rely mainly ...
