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 ...

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 ...

The violent earthquake that struck western India yesterday was born from ponderous but powerful forces deep underground that move entire continents. In many ways, the quake was similar to the deadly ...
