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 ...

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

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 Atlantic Ocean may begin to shrink, said a new study published in the journal Geology. Oceans are not necessarily a permanent fixture on Earth, as they are able to appear and close due to the ...

The Pacific Northwest is at risk for a mega-earthquake because of the Cascadia Subduction Zone. The region is primed ... "We had a very fuzzy low-resolution view before." Devika Rao has worked ...
