Countless seismic faults just as dangerous as the one that triggered Monday's San Simeon earthquake are suspected to be lurking throughout the Bay Area. Scientists have known about some of these ...

Seismic hazard maps issued by the state may underestimate the quake risk in Orange County and should be reevaluated in light of evidence that significant faults are hidden underground, according to ...

It is a common trope in disaster movies: an earthquake strikes, causing the ground to rip open and swallow people and cars whole. The gaping earth might make for cinematic drama, but earthquake ...

As PG&E’s aging Diablo Canyon nuclear power plant is up for a 20-year federal license renewal, one scientist cites new GPS data to suggest there’s a looming seismic threat from an active thrust fault ...

In Japan and areas like the Pacific Northwest where megathrust earthquakes are common, scientists may be able to better forecast large quakes based on periodic increases and decreases in the rate of ...

Massive earthquake along Puente Hills thrust fault in Southern California could cause more damage than the predicted 'Big One' from the San Andreas Fault. Experts say a larger earthquake than the ...

LA HABRA (CBS/AP) — Experts say a bigger earthquake along the lesser-known fault that gave Southern California a moderate shake could do more damage to the region than the long-dreaded "Big One" from ...

NCS links the 5.1-magnitude Assam earthquake to the Kopili Fault and says no aftershocks were recorded after the January 5 tremor.

This week's Friday Field Foto is a close-up view of the Keystone Thrust in southern Nevada. The key criterion for correctly recognizing a thrust fault is to demonstrate that there are older rocks on ...

The most broadly distributed contractional tectonic landforms on Mercury are lobate scarps 2,3,4,5. These scarps are the surface manifestation of thrust faults and are often hundreds of kilometres ...

Scientists citing new research say an earthquake fault along the Los Angeles coast, previously believed to be dormant, is active and could cause a destructive 6.4 magnitude earthquake if it ruptured.

Engineers and scientists experimentally observe surface twisting in thrust faults that can momentarily rip open the earth's surface. It is a common trope in disaster movies: an earthquake strikes, ...
