Anchorage was heavily damaged by the 1964 Great Alaska earthquake (M9.2), when ground failures such as the Turnagain Heights landslide destroyed neighbourhoods. The city sits above the subducting Pacific Plate, so it is exposed to both megathrust earthquakes and deep earthquakes within the slab. The 2018 Anchorage earthquake (M7.1) struck about 40 km beneath the city and caused damage but limited casualties. Major faults include the Aleutian Megathrust and the Castle Mountain Fault. Notable quakes include the 1964 Great Alaska earthquake (M9.2) and the 2018 Anchorage earthquake (M7.1). The seismic risk is very high. Tectonically, Anchorage lies on the North American Plate, where the Pacific Plate subducts beneath it. This page provides real‑time USGS data and historical context for Anchorage.

The region is defined by Aleutian Megathrust, Castle Mountain Fault, and the risk level is classified as Very High. With a population of 290,000, understanding local seismic hazards is crucial.
Anchorage 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 Anchorage was the 1964 Great Alaska earthquake (M9.2). 1964 Great Alaska (M9.2)
Anchorage 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 Anchorage was the 2018 Anchorage earthquake (M7.1). 2018 Anchorage (M7.1)
Yes. Anchorage is crossed by Aleutian Megathrust, Castle Mountain 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.
