Earthquakes are sudden and their shaking can be devastating. But about 20 years ago, a new type of earthquake was discovered. We cannot feel them, and geologists still know very little about them, such as how often they occur.

Hand-dug trenches around Leigh Lake in Grand Teton National Park in Wyoming reveal evidence for a previously unknown surface-faulting earthquake in along the Teton Fault—one occurring about 10,000 years ago.

A University of Iowa-led study has found that a series of Southern California earthquakes last summer increased stress on the Garlock Fault, a major earthquake fault line that has been dormant for at least a century.

A new study from Caltech finds that so-called "slow slip" or "silent" earthquakes behave more like regular earthquakes than previously thought. The discovery opens the door for geoscientists to use these frequent and nondestructive ...

The largest earthquake sequence in Southern California in two decades has taught scientists that large earthquakes can occur in a more complex fashion than commonly assumed. The sequence also loaded up strain on a nearby ...

One of the 24-plus faults that ruptured in the 2016 magnitude 7.8 Kaikōura earthquake has turned out to be even more unusual than scientists first thought and it may prompt a rethink about how seismic hazard is calculated.

For more than a century, a guiding principle in seismology has been that earthquakes recur at semi-regular intervals according to a "seismic cycle." In this model, strain that gradually accumulates along a locked fault is ...
