The 1958 Huslia earthquake on April 7 struck an unusual part of Alaska, near the city of Huslia, about 415 km from Fairbanks. The Ms 7.3[1] earthquake is one of two magnitude 7.0 or greater earthquakes recorded north of 65° latitude, the other being the 1933 Baffin Bay earthquake, and is one of the strongest earthquakes within the interior of the state.[2] The earthquake was a result of compression of the crust due to the subduction of the Pacific Plate under the North American Plate.[3]
