Timeline of the 2016 Pacific hurricane season which broke the record for having the earliest forming storm within the basin. During the season, 22 tropical depressions developed within the basin, 21 of which became tropical storms. 13 of the tropical storms reached hurricane strength, with six achieving major hurricane intensity. Additionally, Tropical Storm Otto entered the basin after crossing over from the Atlantic, thus further contributing to the season total. Four time zones are utilized in the basin: Central for storms east of 106°W, Mountain between 114.9°W and 106°W, Pacific between 140°W and 115°W, and Hawaii–Aleutian for storms between the International Date Line and 140°W. However, for
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
