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.

By combining models of magnitude 9 to 9.2 earthquakes on the Cascadia Subduction Zone with geological evidence of past coastal changes, researchers have a better idea of what kind of megathrust seismic activity was behind ...

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 ...

A team of geologists led by João Duarte gave a presentation at this past month's European Geosciences Union meeting that included a suggestion that the Horseshoe Abyssal Plain may represent the start of a new subduction ...
Using ground motions generated for a range of simulated magnitude 9 earthquakes in the Pacific Northwest, researchers are testing how well reinforced concrete walls might stand up under such seismic events.
