Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Researchers found that an inactive subduction zone under the Strait of Gibraltar may begin migrating into the Atlantic Ocean, commencing the shrinking process. The zone also brings a higher risk ...

In the present-day ocean, there are several early-stage subduction zones with differential geological records, for example, the Puysegur subduction zone to the south of New Zealand.

Not all mountains in the Yellowstone region are volcanic in origin. The Wind River Range, southeast of Yellowstone National ...

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

An earlier study showed that a large subduction zone must have run through the western paleo-Pacific Ocean, which separated the known Pacific plates in the east from a hypothetical Pontus plate in ...

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.

A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...

In subduction boundaries, sediment is shed off the volcanic mountains, and some makes its way to the ocean to be deposited in shallow and deep water marine environments. This sediment is poorly ...

High-Resolution Anisotropic Tomography Reveals Mantle Flow Complexity and Slab-Plume Interactions, Redefining Subduction Zone ...
