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 classified into three ...
Simplified fault map of southern California The faults of Southern California viewed to the southeast, as modeled by the Southern California Earthquake Center. Highlighted in purple are the San Andreas Fault (left) and Santa Monica Bay complex (right). The foreground is in the Santa Barbara Channel, the east-trending zone marks the Transverse ...
New Madrid seismic zone. 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 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 ...
Let's say an earthquake on the southern San Andreas fault that starts near the Mexican border ends up being a magnitude 8, but the earliest estimate says it's a magnitude 6.5. The longer that ...
San Diego State University and Scripps Institution of Oceanography PhD candidate Ryley Hill told The New York Times that “We are not trying to predict any earthquake that is going to happen in ...
The San Andreas Fault Observatory at Depth (SAFOD) was a research project that began in 2002 aimed at collecting geological data about the San Andreas Fault for the purpose of predicting and analyzing future earthquakes. [1] [2] The site consists of a 2.2 km (1.4 miles) pilot hole and a 3.2 km (2 miles) main hole. [3] Drilling operations ceased ...
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.
