The goal is to map which parts of the fault are creeping past each other with little “stickiness,” and which parts appear to be locked together—places where pent-up stress may be released suddenly in a major earthquake.

Viewed from space, the San Andreas Fault looks like a long, narrow valley that marks where the North America plate meets the Pacific plate. This narrow break between the two plates is called a fault. But viewed up close, there are actually many fractures and faultsthat mark the zone where the two plates slide past one each other. Sometimes the boun...
The San Andreas Fault is about 800 miles long (1,287 kilometers), stretching from the Mendocino coast south to the San Bernardino Mountains and the Salton Sea. Geologists divide the fault into northern and southern segments, separated in the middle by a curiously quiet portion that "creeps." [Photo Journal: The Gorgeous San Andreas Fault] The north...
The San Andreas Fault was the site of a massive effort to drill into Earth's crust and investigate a fault at depth. In 2004, work began near the town of Parkfield on the San Andreas Fault Observatory at Depth(SAFOD) to drill nearly 2 miles (3.2 km) into the fault. Parkfield, in central California, pops off a moderate earthquake of around magnitude...
The largest earthquakes in California since European settlers arrived struck in 1857 and 1906 on the San Andreas Fault. The Jan. 9, 1857, Fort Tejon earthquake in southern California, an estimated magnitude 7.9, offset stream channels by as much as 29 feet (9 m). The U.S Geological Survey estimates that a similar-size earthquake today, in the same ...
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. It forms part of the tectonic boundary between the Pacific Plate and the North American Plate .
24 de jun. de 2009 · This image showing a portion of the San Andreas Fault along the San Francisco Peninsula was taken by the UAVSAR instrument on NASA's Gulfstream III research aircraft. The narrow body of water running diagonally along the fault from upper left to lower right is the Crystal Springs Reservoir.
