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.

The Cascadia Subduction Zone is capable of generating powerful earthquakes. The study found compact sediments along the coast of Washington and northern Oregon, a result that suggests that the ...

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants ...

Megathrust earthquakes occur when stress at subduction zones is released, causing significant plate slippage. These events disrupt long-term tectonic changes, complicating modeling efforts.
