Subduction zones are the most important sites of material exchange between the crust and mantle on Earth. They are also the locations where the largest deposits of strategic metals, such as copper, ...

Mid-ocean ridge basalts (MORBs), located far from subduction zones, are typically thought to be unaffected by subduction ...

The Hikurangi Subduction Zone is where the Pacific plate drops westward under the Australian plate. It sits just off the east coast of the North Island. Subduction zones generate the largest ...

A recent study reveals that slow ocean expansion 15-6 million years ago caused sea levels to change and drop by up to 30 ...

In the past, such anomalies were usually linked to subduction zones—places where one tectonic plate slides beneath another. In those zones, slabs of oceanic crust plunge into the mantle ...

The Juan de Fuca Plate is slowly being subducted beneath the North American Plate along the Cascadia Subduction Zone, which runs from northern California to British Columbia. This tectonic ...

While this causes “strike slip” quakes that are normally less powerful than those seen in “subduction zones” like Indonesia’s Sumatra, where one plate slides under another, they can ...

Subduction zones are the most important sites of material exchange between the crust and mantle on Earth. They are also the locations where the largest deposits of strategic metals, such as copper ...

Coos Bay, home to more than 15,000 people, lies within just eight miles of the Cascadia Subduction Zone: a megathrust fault where the Juan de Fuca plate slides beneath the North American plate.
