The Cascadia Subduction Zone is “unusually quiet,” for a megathrust fault, making it more difficult for scientists to ...

EUGENE, Ore. (NBC) -- When an earthquake rips along the Cascadia Subduction Zone fault, much of the U.S. West Coast could shake violently for five minutes, and tsunami waves as tall as 100 feet could ...

Map highlighting the Atlantic subduction zones, the fully developed Lesser Antilles and Scotia arcs on the western side and the incipient Gibraltar arc on the eastern side. From Duarte et al., 2018.

Earthquakes occur along fault lines between continental plates, where one plate is diving beneath another. Pressure builds between each plate, called fault stress. When this stress builds enough to ...

Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis. Groundbreaking research has provided new insight into ...

Earth's "gold kitchen" lies deep beneath the seafloor. Island arcs, whose volcanoes form above subduction zones where one ...

Even long-lived subduction zones eventually die, and scientists believe they are witnessing the slow death of one in the northern end of the Cascadia subduction zone. A new study using seismic data ...

Jessica DePaolis (second from left) and the team of researchers studied and compared sedimentary core samples in Montague Island, Alaska, and found evidence that four of the past eight earthquakes ...

Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in ...
