The Shaky Backbone of California California lies at the boundary between two enormous tectonic plates. These plates don’t ...

In the days following a 4.2-magnitude earthquake in Gig Harbor, at least four aftershocks were too small to feel, according to the Pacific Northwest Seismic Network.

At the Seismological Society of America's Annual Meeting, researchers posed a seemingly simple question: how wide are faults? Using data compiled from single earthquakes across the world, Christie ...

Scientists do not have an ability to predict when earthquakes will occur, but a team announced today a major step toward ...

Researchers say stress on Southern California’s San Andreas and San Jacinto faults has reached some of the highest levels seen in a 1,000-year simulation. Because both faults are highly stressed at ...

Recent research indicates elevated stress levels at Cajon Pass, affecting interactions between the San Andreas and San ...

California's earthquake faults are more likely to be "overdue" for a major quake than those elsewhere in the world, new research reveals—a finding that could have implications for how earthquake risk ...

Officials have been promoting this year's Great California ShakeOut, an earthquake drill Californians participate in on Oct.

Scientists discovered that deep earthquake faults can heal far faster than expected, sometimes within hours. Slow slip events in Cascadia reveal repeated fault movements that only make sense if the ...

Learn how faults beneath the Earth's surface can heal themselves after slowly releasing stress from the movement of tectonic plates. After faults deep in the Earth get shaken up from a ...
