The Earth's lithosphere is the rigid outer shell of the planet and is broken into several tectonic plates. These plates are in constant motion over the semi-fluid asthenosphere underneath them. Much ...

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 ...

For decades, the end-stage life of a subduction zone existed only in theory. Now, for the first time in geologic history, scientists are bearing witness to the Juan de Fuca Plate tearing apart and ...

SAN FRANCISCO -- Scientists say there's new evidence that two of the best-known earthquake fault lines on the West Coast are in sync and that has the potential for a major disaster. A new study by ...

Understanding the origins of the Ring of Fire, the most seismically active place on Earth, is famously difficult as geologic evidence is destroyed in the process. Now a new study suggests that ...

Subduction zones, where one tectonic plate dives underneath another, drive the world's most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

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 ...

The pressure keeps building below the Earth’s surface off the coast of the Pacific Northwest, and a multi-layered disaster could strike at any time. A huge earthquake is brewing along the Cascadia ...

(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 ...

When Washingtonians talk about the possibility of a major earthquake in the Cascadia Subduction Zone, the conversation typically focuses on the immediate impacts: the threat of casualties, building ...

PORTLAND, Ore. (KOIN) – A major earthquake waiting to strike the Cascadia Subduction Zone isn’t the only natural disaster looming in the Pacific Northwest, new research shows. A powerful quake, ...
