The geology of the Cascadia subduction zone has largely staved off climate-related sea-level rise in the Pacific Northwest, ...

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.

At the subduction zone, the Juan de Fuca plate is being forced beneath the continental North American plate. This causes the North American plate to bow upward slightly, pushing the land level higher.
