After more than 300 years of quiet, the Cascadia Subduction Zone is on the verge of releasing immense energy. This underwater ...

The ground beneath the United States is never truly still. S. could experience potentially damaging earthquakes and intense ...

SEATTLE — Newly-released research led by the University of Washington (UW) showed that a feature scientists hypothesized was present along the Cascadia Subduction Zone is missing in places. What does ...

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 ...

A megathrust earthquake is coming for the Pacific Northwest. But new imaging of undersea faults and fractures has given ...

This satellite-based model of Earth shows the tectonic boundaries (yellow lines) in the eastern Pacific Ocean. The San Andreas Fault and the Cascadia Subduction Zone both occur along the North ...

Scientists discovered a crack under the sea off Vancouver Island, NFZ in Cascadia region, that could alter Pacific subduction.

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.

The Cascade Subduction Zone affects where the ocean meets the land, and that land is rising in some parts of the Oregon Coast.

(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...
