What's clear from the study is that while California's next "Big One" may share some characteristics of previously documented ...

The massive fault line could trigger California’s next catastrophic earthquake, but how likely is the so-called ‘Big One’?

The San Andreas Fault is about 746 miles (1,200 km) long and about 10 miles (16 km) deep. While the San Andreas is a giant fault that is even visible from space, if you zoom in, you'll see a ...

Earthquakes on the Puente Hills thrust fault could be particularly dangerous because the shaking would occur directly beneath ...

But the San Andreas Fault has about 150 miles (241 km) of slip between either side, meaning that volcanic rocks in Pinnacles National Park match those much farther south, in Los Angeles County.

The southern San Andreas fault in California is in a seismic drought, going more than 300 years without a major earthquake. New research shows the lack of seismic activity may be due to the drying ...

The last major quake to occur along the San Andreas fault zone was in 1906, when a 7.9-magnitude earthquake and subsequent fire leveled parts of San Francisco and killed 3,000 people, the ...

The CoreLogic analysis shows that a magnitude 8.3 earthquake along the San Andreas – which was previously thought possible only on the northern segment of the fault line – could result in a ...

When the magnitude-6.4 earthquake on the Fourth of July was followed by an even bigger 7.1 quake Friday night, talk of the "Big One" became inevitable and Google searches for "San Andreas fault ...

Thirty years ago, on Oct. 17, 1989, a magnitude 6.9 earthquake along the San Andreas Fault caused Bay Area buildings to crumble and freeways to collapse.
