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 .
The most famous fault in the U.S. is San Andreas. ... The fault line absolutely devastated San Francisco back in 1906, and also wreaked havoc in southern California in 1857.
A report from 2008 – co-authored by Jones – estimated that even a magnitude 7.8 quake on the San Andreas Fault would cause fewer fatalities and less economic damage.
The most prominent red line is the San Andreas fault (overall probability of rupture ~70%). The red zone at the northwest corner is the southern end of the Cascadia subduction zone, that on the California-Nevada state line is Walker Lane. Modified from UCERF-2 figure 35.
A simulation of a plausible major southern San Andreas fault earthquake — a magnitude 7.8 that begins near the Mexican border along the fault plane and unzips all the way to L.A. County's ...
The most studied earthquake faults (such as the Nankai megathrust, the Wasatch fault, and the San Andreas Fault) appear to have distinct segments. The characteristic earthquake model postulates that earthquakes are generally constrained within these segments. [9]
The last big earthquake in this area on the San Andreas caused one part of the fault to move past the other by 12 to 14 feet, making it a likely magnitude 7.3 or 7.4 earthquake. Rockwell said he ...
[186] [t] It was based on an observation that the Parkfield segment of the San Andreas Fault [u] breaks regularly with a moderate earthquake of about M 6 every several decades: 1857, 1881, 1901, 1922, 1934, and 1966. [187] More particularly, Bakun & Lindh (1985) pointed out that, if the 1934 quake is excluded, these occur every 22 years, ±4.3 ...
