A rare type of deep underground earthquake occurring in the Earth’s mantle has finally been isolated and mapped by Stanford researchers.

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 ...

A new study has uncovered new earthquake faults in the Wairarapa valley, four of which are close to some of the region's ...

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 ...

A new type of seismic threat is gaining attention among geologists—and it could have serious implications for California. Known as “supershear” earthquakes, these rare but devastating quakes travel ...

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 ...

Earthquake faults deep in the Earth can glue themselves back together following a seismic event, according to a new study led by researchers at the UC Davis. The work, published Nov. 19 in Science ...

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 -- ...
