Earthquakes in Alaska

Latest earthquakes in Alaska, United States: 48 in the last 24 hours, 2630 in the last 30 days. Updated Nov 10, 2026 00:18 UTC.

Alaska is the most seismically active state in the country. South of the mainland and along the Aleutian Islands, the Pacific plate dives beneath North America, producing a steady stream of earthquakes from the surface down to well over 100 km deep. On average the state has a magnitude 7 earthquake about once a year, and most of them strike offshore or in remote areas. The most notable is the magnitude 9.2 Good Friday earthquake of March 28, 1964 near Prince William Sound, the largest in U.S. history and the second largest ever recorded anywhere. Its shaking lasted for roughly four minutes, and the tsunamis it triggered caused most of the deaths. The USGS catalog also lists the magnitude 8.7 Rat Islands earthquake of 1965 and the magnitude 7.1 Anchorage earthquake of November 30, 2018, which damaged roads and buildings. The list below shows the earthquakes recorded in Alaska over the past 30 days.
