Subduction zones are major driving forces behind this tectonic conveyor belt, as they pull oceanic crust and upper mantle down to depth, recycling the rocks and dragging continents around in the ...

Researchers developed a fourth-generation buoy in Seattle that can detect an earthquake-triggered tsunami 10-15 minutes earlier than the previous generation.

MOUNT VERNON, Wash. — A 2.9 magnitude earthquake was recorded early Tuesday morning near Mount Vernon. The shakes were recorded around 1:59 a.m. Tuesday about 3 kilometers west of Mount Vernon ...

The Cascadia Subduction Zone, stretching from northern California to British Columbia, is one of the most dangerous seismic hotspots in North America, capable of producing a massive 9.0 magnitude ...

Saltmarshes are “significant” carbon stores, but are at risk from rising sea levels, new research reveals. A report from conservation charity WWF in partnership with insurance giant Aviva ...

The same forces that cause the coast to slowly rise over the years triggers a reversal when the subduction zone quake happens. In a matter of minutes, the tension releases, and the land level ...

The solar-powered tower continuously measures the exchange of carbon dioxide between the saltmarsh and atmosphere, capturing how much carbon is absorbed or released throughout the year. This ...

A Virginia Tech study highlights the potential for a mega-tsunami triggered by a major earthquake in the Cascadia Subduction Zone. This fault line threatens the Pacific Northwest with a possible ...

The 1980 eruption cycle made Mount St. Helens one of the most famous volcanoes in the Cascades. But it is far from the only volcano in the range.
