Aleutian subduction zone west (Andreanof Island) where LFEs occur at greater depths (~75 km) than in the east where the plate is younger (~45 km near Kodiak Island). This may be because the depths at which the hydrous minerals release water and produce tremors are greater when the plate is older, colder, and subducting faster. Aleutian subduction zone The Aleutian subduction zone is a ~2500 mile-long convergence boundary between the North American Plate and the Pacific Plate, that extends from the Alaska Range to the Kamchatka Peninsula. Here, the Pacific Plate is being subducted underneath the North American plate and the rate of
