An earthquake typically sets off ruptures that ripple out from its underground origins. But on rare occasions, seismologists have observed quakes that reverse course, further shaking up areas that ...

A new kind of earthquake has been detected in western Canada, one that shakes the ground slower and longer than typical seismic events. These earthquakes, recorded during hydraulic fracturing for oil ...

At the Seismological Society of America's Annual Meeting, researchers posed a seemingly simple question: how wide are faults? Using data compiled from single earthquakes across the world, Christie ...

Shrinking lakes across the Tibetan Plateau may be doing more than altering the region’s hydrology. New research suggests that the slow disappearance of massive water bodies over tens of thousands of ...

Scientists are warning that underexplored "supershear" earthquakes could have serious impacts in California, particularly near the infamous San Andreas Fault. "The San Andreas is the perfect setting ...

When most people think of earthquakes, they think of California fault lines. But the most active earthquake zone east of the Rocky Mountains runs straight through the middle of the country — including ...

Scientists studying Kīlauea found that a major 2018 earthquake may have paused slow fault slip for nearly 60 years beneath the volcano.

Forecasting earthquakes presents a serious challenge on land, but in the oceans that cover around 70% of Earth's surface it is all but impossible. However, the vast network of undersea cables that ...

When we think of earthquakes, we imagine sudden, violent shaking. But deep beneath the Earth’s surface, some faults move in near silence. These slow, shuffling slips and their accompanying hum—called ...
