The geometric structure of rocks where earthquakes occur could play a key role in determining their location and strength, researchers have found. A study, carried out by geologists at Brown ...

Researchers say ubiquitous evidence for ongoing geological carbon sequestration in mantle rocks in the creeping sections of the San Andreas Fault is one underlying cause of aseismic creep along a ...

In the Pacific Northwest, big faults like the Cascadian subduction zone located offshore, get a lot of attention. But big faults aren't the only ones that pose significant hazards, and a new study ...

A new study shines a light on a system of earthquake faults in the San Francisco Bay Area that most residents don’t even know exists. The Foothill Thrust Belt faults are deep under Silicon Valley, and ...

Readers ask: “Where exactly is the Balcones Fault?” And while we’re at it, “What precisely is the Balcones Escarpment?” Excellent questions. Even some old-timers can’t tell you exactly where these two ...

The Mendocino Triple Junction off the coast of Northern California is the point where three tectonic plates meet. A new study reveals at least five moving pieces deep below the Earth's surface make up ...

SAN DIEGO (KSWB) — Earthquakes can’t be predicted but a new scientific assessment by the United States Geological Survey (USGS) has revealed areas where scientists predict “damaging” earthquakes are ...

A major California fault once thought to be stable is quietly shifting beneath neighborhoods, schools, and it could lead to a powerful quake with no warning. A new US geological (USGS) survey showed ...
