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 ...

The Pacific Northwest is known for its towering trees, beautiful landscapes and breathtaking coast. But what sits about 70 miles off that coast, and anywhere from 300 to 10,000 ft below the ocean's ...

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, ...

A budding subduction zone offshore of Spain heralds the start of a new cycle that will one day pull the Atlantic Ocean seafloor into the bowels of the Earth, a new study suggests. Understanding how ...

One of the biggest crash scenes on Earth, a subduction zone is a spot where two of the planet's tectonic plates collide and one dives, or subducts, beneath the other, according to the National Oceanic ...

The magnitude of the 2011 Tohoku quake (M 9.0) caught many seismologists by surprise, prompting some to revisit the question of calculating the maximum magnitude earthquake possible for a particular ...

When a slab slides beneath an overriding plate in a subduction zone, the slab takes on a property called anisotropy, meaning its strength is not the same in all directions. Anisotropy is what causes a ...
