Why are earthquakes so common in Alaska?

Most of these earthquakes—and all major earthquakes—can be traced to the movement of tectonic plates. Alaska’s largest earthquakes, exceeding magnitude 8 and even 9, occur primarily in the shallow part of the subduction zone, where the crust of the Pacific Plate sticks and slips past the overlying crust.
