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 ...

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 ...

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 ...

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 ...

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 ...

Geologists have been given a “one-of-a-kind” window into Scotland’s geological past as they analyse core rock drilled from the Great Glen Fault during investigations for a hydro-storage scheme. The ...

California experienced five earthquakes within a short period of time on Friday and Saturday, amid ongoing concerns about seismic safety in the region. Four of the five struck near Avenal, California ...
