Alaska records more earthquakes than any other US state, with frequent activity along the Aleutian subduction zone. Alaska has had one M9+ earthquake – the 1964 Great Alaska Earthquake (M9.2), the second largest ever recorded. Major faults include Aleutian Megathrust, Denali Fault, Fairweather Fault. Notable quakes include 1964 Great Alaska (M9.2), 2002 Denali (M7.9). The seismic risk is very high. Tectonically, Alaska lies on pacific plate subducting beneath north american plate. This page provides real‑time USGS data and historical context for Alaska.

The region is defined by Aleutian Megathrust, Denali Fault, Fairweather Fault, and the risk level is classified as Very High. With a population of 730,000, understanding local seismic hazards is crucial.
Alaska lies on Pacific Plate subducting beneath North American Plate. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In some regions, strike‑slip faults produce frequent moderate earthquakes.

The strongest recorded earthquake in Alaska was the 1964 Great Alaska earthquake (M9.2). 1964 Great Alaska (M9.2)
Alaska experiences approximately 500-1,500 earthquakes per year, with 50-200 felt (M3.0+) and 5-10 potentially damaging events (M5.0+) annually, according to USGS historical data.
The most recent major earthquake in Alaska was the 2018 Anchorage earthquake (M7.1). 2018 Anchorage (M7.1)
Yes. Alaska is crossed by Aleutian Megathrust, Denali Fault, Fairweather Fault, making it prone to seismic activity. The seismic risk level is classified as Very High.
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks. Prepare an emergency kit with water, food, first aid, and a flashlight.
