When a huge earthquake struck near Kamchatka, the SWOT satellite captured an unprecedented, high-resolution view of the resulting tsunami as it crossed the Pacific. The data revealed the waves were ...

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 ...

For the first time, scientists have observed a subduction zone – the place where one tectonic plate dives beneath another – actively breaking apart. The research offers a rare, high-resolution look at ...

Just off the coast of the Pacific Northwest is the Cascadia Subduction Zone, a complex collection of earthquake faults created by one tectonic plate pushing its way under another. Every 400-600 years, ...

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 ...

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 ...

Experts have issued a warning about a potential “mega tsunami” that could sweep away entire communities with its massive waves. Alaska, Hawaii and the West Coast of the mainland US face an ongoing ...
