A new study of California's earthquakes say that building pressure underneath two major fault lines converging at Cajon Pass ...

Los Angeles could be edging closer to “the big one,” with new research finding earthquake stress has reached its highest ...

For more than 150 years, Southern California’s biggest faults have been quietly building up pressure beneath the ground. A ...

Los Angeles could see a major earthquake ...

What does that mean for earthquake risk?

Record stress along the San Andreas and San Jacinto faults could trigger a major earthquake around Los Angeles.

Scientists used to think so-called “slow slip events” were “theoretically impossible.” Now these subtle tectonic shifts could ...

Scientists say the San Andreas and San Jacinto faults are more stressed than at any time in 1,000 years, raising questions about future California quakes.

The fault lines have reached “unprecedented levels,” according to the study.

Stress accumulating in the southern San Andreas fault. (Burkhard et. al., J. Geophys. Res. Solid Earth, 2026) It's called California's Big One for a reason. For more than a century, tectonic pressure ...

California sits on an active plate boundary where the Pacific and North American plates grind past each other, producing frequent earthquakes.

According to the study, both fault systems have reached exceptionally high stress levels due to centuries of tectonic strain.
