Rocks once buried deep in ancient subduction zones—where tectonic plates collide—could help scientists make better predictions of how these zones behave during the years between major ...

A record-breaking deep earthquake registered in May 2015 offshore of Japan likely was not a tectonic event but triggered by a ...

The Cascadia subduction zone, where the oceanic Juan de Fuca plate descends beneath the overlying North American plate, extends 1100 km from northern California to northern Vancouver Island.

Scientists have solved the mystery of how earthquakes can occur 420 miles deep inside Earth, where extreme pressure and heat ...

They also found isotopic signatures corresponding to other subduction zone rocks such as abyssal serpentinite. "Our research indicates that these giant anorthosites likely originated from the ...

However, a new high-resolution model shows that these remnants can also be found far from subduction zones ... in a press statement, “or zones where iron-rich rocks accumulate as a consequence ...

Amid Earth’s mobile tectonic plates, subduction zones arise as regions of intense geological activity and concentrate minerals into ore deposits like gold.

A re-examination of the 2015 Bonin Islands earthquake disproved earlier claims of a record-breaking deep aftershock in the ...

Now, scientists aim to get their clearest picture yet of the complex mechanics of our big-risk Hikurangi Subduction Zone – and what sets it apart from similar systems around the planet.

This indicates the presence of zones of rocks that are colder ... in an area known as subduction zones, where two plates meet and one subducts beneath the other into the Earth's interior.
