Recent seismic imaging off Vancouver Island has revealed something extraordinary: a tear in the subducting oceanic plate beneath the Cascadia Subduction Zone. The finding briefly raised the public’s ...

The Cascadia Subduction Zone off the Pacific Northwest is overdue for an earthquake – and when it happens, coastal ...

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

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

Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the ...

Surface volatiles—chemical substances that easily become gases or fluids at relatively low temperatures and pressures—are ...

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 ...

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 barrel toward shore.

New research published recently in the journal Science Advances considers the process of tectonic plate subduction. The study is a collaboration between scientists at the Scripps Institution of ...

How is plate subduction factory operated during continental collision? How do physical mixing and chemical reaction proceed at colliding continental margins of different depths? How is continental ...

The first step in gold’s journey does not happen in a mine, a fault, or a hydrothermal vent. It begins far deeper, in mantle ...
