Anchorage, Alaska experiences frequent earthquakes, including both small daily tremors and occasional damaging events, because it sits near the boundary where the Pacific Plate subducts beneath the North American Plate along the Alaska–Aleutian subduction zone. Recently, the area has seen only small quakes around magnitude 2–3 near Anchorage and nearby communities, with no major damage reported.

Recent and current quakes

  • In the last few days near Anchorage, earthquakes have mostly been in the magnitude 1.5–3.5 range at depths of about 10–40 km, which are commonly felt as light shaking or not felt at all and typically do not cause damage.
  • Regional monitoring centers continuously log these events and publish near–real‑time maps and lists so residents can check if a specific shaking episode was from an earthquake.

Notable Anchorage earthquakes

  • On November 30, 2018, a magnitude 7.1 earthquake struck just north of Anchorage, damaging roads, some buildings, and infrastructure, injuring over 100 people but causing no direct fatalities.
  • On March 27, 1964, the Great Alaska Earthquake (magnitude 9.2) occurred southeast of Anchorage; the city suffered severe structural damage and landslides, making it the most powerful recorded earthquake in U.S. and North American history.

Very recent “Anchorage earthquake” news

  • In April 2025, a magnitude 4.7 earthquake on the Kenai Peninsula, about a few dozen miles south of Anchorage, caused noticeable shaking in Anchorage and nearby communities but no reported damage or tsunami threat.
  • A separate magnitude‑6 class event in Alaska in late November 2025 occurred west of Susitna (in south‑central Alaska), and is part of the same active tectonic region that affects Anchorage, though it was not directly beneath the city.

What to do if you felt one

  • For real‑time confirmation, residents should check the U.S. Geological Survey and the Alaska Earthquake Center “recent earthquakes” pages, which list time, magnitude, and location for each event.
  • During strong shaking, the standard advice is to drop, cover, and hold on, and afterward check for gas leaks, structural damage, and local emergency alerts, following guidance from local emergency management resources.
