Earth’s surface is constantly shifting, shaped by the slow but powerful movement of tectonic plates. While some plates have ...

Subduction is thus a key process of the tectonics and geodynamics of the Earth. However, the formation mechanism of a new subduction zone, i.e., subduction initiation (SI), is widely debated.

Washington hasn’t seen a major earthquake since the 6.8 magnitude Nisqually earthquake in 2001. The Cascadia Subduction Zone, ...

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

Earthquakes occur along fault lines between continental plates, where one plate is diving beneath another. Pressure builds between each plate, called fault stress. When this stress builds enough to ...

Thursday's morning earthquake follows several other seismic events that have shaken western Washington. A 3.4 magnitude ...

What happens, then, to keep the Earth the same size? The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. The boundary ...

The 3.9 magnitude earthquake hit at 4:18 p.m. on the Olympic Peninsula, according to the United States Geological Survey.

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