Quizplus · Accepted Answer

During the time between megathrust earthquakes on the Cascadia Subduction Zone, the over-riding continental North American plate undergoes uplift and shortening. This is because as the Juan de Fuca plate subducts beneath the North American plate, it accumulates stress and eventually releases it in the form of a megathrust earthquake. This causes the North American plate to uplift and shorten. Between these earthquakes, the North American plate continues to slowly uplift and shorten due to ongoing tectonic forces.
