At the Cascadia subduction zone in the Pacific Northwest, one tectonic plate is moving underneath another. New experimental work at UC Davis shows how rocks on faults deep in the Earth can cement ...

Teasing out just what is happening below the Earth's shifty surface during an earthquake is no simple feat, but scientists have found a new tool that may help get a clearer picture of the minute ...

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 ...

After faults deep in the Earth get shaken up from a stress-relieving event, they can be patched right back up to continue the endless earthquake cycle. However, this self-healing ability doesn't apply ...

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 ...

Scientists have discovered a new seismic link between two of the West Coast's largest earthquake faults, and it could be the recipe for a major natural disaster. The study out of Oregon State ...

Below California’s famed beaches, mountains and metropolitan areas lies a sinister web of earthquake faults — some so infamous that their names are burned into the state’s collective consciousness.

Earthquake faults deep in Earth can glue themselves back together following a seismic event, according to a new study led by researchers at the University of California, Davis. The work, published in ...
