Those living in southern California love our mountains, but how many know the mountains are there because of the San Andreas fault? The earthquakes of California are caused by the movement of huge blocks of the earth's crust- the Pacific and North American plates. 3651 Trousdale Parkway #169 And most of these are not on the major faults listed above. Bonadelle Ranchos-Madera Ranchos 10.2 km from Southern California Coast Edition (PDF). Large earthquakes anywhere in the Southern California Coast area can affect you, even if the shaking is not strongly felt where you happen to be. This table includes significant earthquakes having epicenters outside of California but within approximately 100 miles of California's border. Cobb Mammoth Lakes The outlook improved when Professor Andrew Lawson brought the state's first monitoring program online at the University of California, Berkeley in 1910 with seismologist Harry Wood, who was later instrumental in getting the Caltech Seismological Laboratory operational in the 1920s.

Other sources for the occurrence of earthquakes usually came from ship captains and other explorers. Central Coast If you live in southern California, one or more of these faults is probably near you.
Lone Pine Higher standards were established for fire stations, hospitals, and schools and construction of dwellings was also restricted near active faults. at 16:02 July 20, 2022 UTC, Location:

In a remote area, a mix of geophysical methods identifies magma transfer below the seafloor as the cause. Boron For the period 18502004, there was about one potentially damaging event per year on average, though many of these did not cause serious consequences or loss of life. To become familiar with earthquake vocabulary, you may want to read the "What Should I Know" section first. 25.2 km from There are over a hundred other active faults in the region that can produce smaller earthquakes like the 1994 Northridge earthquake. 39.2 km from It terminates in the south at the Salton Sea where displacement transitions to a series of spreading centers and transform faults, beginning with the Brawley Seismic Zone in the Imperial Valley.
Many other faults are found directly beneath our cities in some of the most densely populated areas. This system of faults terminates in the north at the Mendocino Triple Junction, one of the most seismically active regions in the state, where earthquakes are occasionally the result of intraplate deformation within the Gorda Plate. at 21:21 July 19, 2022 UTC, Location: Epicenter at 38.826, -122.803
