Anchorage, Alaska – A magnitude 5.9 earthquake struck offshore in the western Aleutian Islands early Thursday, shaking waters west of Adak but posing no tsunami danger, according to the National Tsunami Warning Center. The quake struck at 3:08 a.m. local time and was centered about 145 miles west of Adak, Alaska, at a depth of 75 miles.
According to the U.S. Geological Survey, the earthquake was recorded roughly 50 miles northeast of Amchitka. While no tsunami alerts were issued, scientists noted the potential for aftershocks over the next week, with a 76% chance of tremors at magnitude 3 or higher. Stronger aftershocks, including those above magnitude 5, remain possible though less likely.
