A new method produces improved surface strain rate maps

Earthquakes occur when tectonic strain that has gradually accumulated along a fault is suddenly released. Measurements of how much Earth's surface deforms over time, or the strain rate, can be used in seismic hazard models ...

Ancient lake contributed to past San Andreas fault ruptures

The San Andreas fault, which runs along the western coast of North America and crosses dense population centers like Los Angeles, California, is one of the most-studied faults in North America because of its significant hazard ...

Q&A: Behind the scenes with an earthquake scientist

Sylvain Barbot is trying to do what can't be done yet: reliably predict earthquakes. The assistant professor at the USC Dornsife College of Letters, Arts and Sciences knows that it's impossible—at least not yet. But he ...

Deep underground forces explain quakes on San Andreas Fault

Rock-melting forces occurring much deeper in the Earth than previously understood appear to drive tremors along a notorious segment of California's San Andreas Fault, according to new USC research that helps explain how quakes ...

San Andreas Fault

The San Andreas Fault is a continental transform fault that runs a length of roughly 800 miles (1,300 km) through California in the United States. The fault's motion is right-lateral strike-slip (horizontal motion). It forms the tectonic boundary between the Pacific Plate and the North American Plate.

The fault was first identified in Northern California by UC Berkeley geology professor Andrew Lawson in 1895 and named by him after a small lake which lies in a linear valley formed by the fault just south of San Francisco, the Laguna de San Andreas. Following the 1906 San Francisco Earthquake, it was Lawson who also discovered that the San Andreas Fault stretched well southward into Southern California.
