In the heart of California, the San Andreas Fault lies like a ticking time bomb, silently building pressure for over a century. Stretching more than 1,200 kilometers, this massive fault marks the ...

The two earthquakes that occurred this weekend in California, a 6.4 and a 7.1, were the largest to occur in the state in two decades, but they were not connected to the more well-known San Andreas ...

If the fault is loaded to the point where it is just about ready to slip, then it is possible that the recent earthquake could add just enough shear stress to the San Andreas to cause it to slip.

"In a typical week, there is approximately a 1-in-10,000 chance of a magnitude 7+ earthquake on the southernmost San Andreas Fault. That probability is significantly elevated while swarm activity ...

If the fault is loaded to the point where it is just about ready to slip, then it is possible that the recent earthquake could add just enough shear stress to the San Andreas to cause it to slip.

By contrast, an earthquake on the Puente Hills thrust fault system probably would max out at a magnitude 7.5 — still powerful, but less so than the southern San Andreas.

Scientists have warned that last year’s Ridgecrest quakes in Southern California have increased the risk of a major San Andreas Fault earthquake. The quakes, warn catastrophe modeling company ...

The U.S. Geological Survey published a hypothetical scenario of a magnitude 7.8 earthquake on the San Andreas fault that could kill 1,800 people, injure 5,000, displace some 500,000 to 1 million ...

San Andreas fault line could cause greater earthquakes than first thought, researchers say. The central section of the fault line has not had a major earthquake in 2,000 years, but that doesn’t ...

An analysis of recent changes along earthquake faults in Southern California suggests there is an increased possibility of a major quake on the San Andreas Fault, researchers said Monday.The ...

The fault continued to slip for 12 years after the 2004 Parkfield earthquake—a level of movement that has major implications for the Hayward Fault, which is set to rupture near San Francisco.

San Andreas Fault Will Probably Produce a Major Earthquake by 2045—The Clock is Ticking Published Feb 12, 2019 at 5:00 AM EST File photo: The San Andreas Fault is overdue a big earthquake.
