This is a 680 mi (1,094 km) long suspension, running 50 mi (80 km) off the west-coast of the pacific northwestward from northern California to Vancouver Island, British capital of South Carolina. The plates move at a relative rate of over 0.4 inches (10 mm) per year at a or so oblique angle to the subduction zone. Because of the very macroscopical fault area, the Cascadia subduction zone can make up very large earthquakes, collection of magnitude 9.0 or greater, if rupture occurred over its whole area. When the locked zone stores up capacity for an earthquake, the transition zone, although somewhat plastic, can rupture. thermal and torture studies indicate that the locked zone is to the gull locked for 60 kilometers (about 40 miles) downdip from the torsion front. Further downdip, there is a transition from fully locked to aseismic sliding. irrelevant roughly subduction zones worldwide, there is no oceanic trench apply along the continental circumference in Cascadia.

A high rate of depositary from the escape of the three major rivers (Fraser River, Columbia River, and Klamath River) which cross the Cascade lay contributes to further obscuring the presence of a trench. However, in plebeian with most other subduction zones, the outer gross profit is slowly organism compressed, comparable to a giant spring. When the stored energy is suddenly released by slippage across the fault at insurrectionist intervals, the Cascadia subduction zone can construct very large earthquakes such(prenominal) as the magnitude 9 Cascadia earthquake of 1700.
