San Andreas Fault. The San Andreas Fault is a continental right-lateral strike-slip transform fault that extends roughly 1,200 kilometers (750 mi) through the U.S. state of California. [1] It forms part of the tectonic boundary between the Pacific Plate and the North American Plate. Traditionally, for scientific purposes, the fault has been ...
The 2015 Uniform California Earthquake Rupture Forecast, Version 3, or UCERF3, is the latest official earthquake rupture forecast (ERF) for the state of California, superseding UCERF2. It provides authoritative estimates of the likelihood and severity of potentially damaging earthquake ruptures in the long- and near-term.
The Newport–Inglewood-Rose Canyon Fault Zone. The Newport–Inglewood Fault is a right-lateral strike-slip fault [1] in Southern California.The fault extends for 47 mi (76 km) [1] (110 miles if the Rose Canyon segment is included) from Culver City southeast through Inglewood and other coastal communities to Newport Beach at which point the fault extends east-southeast into the Pacific Ocean.
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 Rose Canyon Fault is a right-lateral strike-slip fault that runs in a north–south direction off the coast of San Diego County, California until it comes ashore near downtown San Diego. The fault is linked to the Newport–Inglewood Fault (NIFZ) in the north and either the Agua Blanca Fault or San Miguel–Vallecitos Fault Zone in the ...
The 1812 San Juan Capistrano earthquake, also known simply as the Capistrano earthquake or the Wrightwood earthquake, [ 6 ] occurred on December 8 at 15:00 UTC in Alta California. At the time, this was a colonial territory of the Spanish Empire. Damage occurred at several of the missions in the region of Pueblo de Los Ángeles, including ...
USGS map showing faults that span the Pacific–North America plate boundary. The Hayward Fault Zone is a right-lateral strike-slip geologic fault zone capable of generating destructive earthquakes. The fault was first named in the Lawson Report of the 1906 San Francisco Earthquake in recognition of its involvement in the earthquake of 1868. [1]
Since the three damaging earthquakes that occurred in the American Midwest and the United States East Coast (1755 Cape Ann, 1811–12 New Madrid, 1886 Charleston) were well known, it became apparent to settlers that the earthquake hazard was different in California. While the 1812 San Juan Capistrano, 1857 Fort Tejon, and 1872 Owens Valley ...
