The Earthquake Ready Burnside Bridge Project has been delayed until 2028 due to uncertainty on a federal level, but the ...

This study, published in Earth and Planetary Physics, explores the subduction thermal state, slab metamorphism, and seismic ...

A subduction zone is created where two plates converge, with one sinking into the mantle. Dynamics along the plate interface create earthquakes, magma generated above the sinking slab leads to ...

This area, called the Cascadia Subduction Zone, hosts a megathrust fault, a place where tectonic plates move against each ...

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

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 ...

Washington hasn’t seen a major earthquake since the 6.8 magnitude Nisqually earthquake in 2001. The Cascadia Subduction Zone, capable of producing a 9.0 magnitude earthquake, last produced a major ...

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