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 ...

After the House of Representatives passed a resolution on Tuesday to fund the federal government and avoid a shutdown, two ...

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

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.

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

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

When plates come together at convergent boundaries, they often slide under each other, which is called subduction. All of these movements can cause earthquakes. Earthquakes can build mountains or tear ...

With Washington’s location along the Cascadia Subduction Zone and several active fault lines in the state, more than 1,000 earthquakes occur in the state each year, according to the Washington ...

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

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