Faults in the Saint Elias region exhibit thrust and reverse slip while there is localised strike-slip deformation evident in some earthquake fault plane solutions. The Saint Elias area is located in the transition area between the zones of convergence and strike-slip plate motions. This area was also the location of two 330:

The earthquake occurred beneath the Chugach and Saint Elias ranges and was observed by 50 seismic stations in the southeastern part of the state, operated by the United States Geological Survey. 489:. The shaking was widespread, with people reportedly feeling the earthquake 1,200 km (750 mi) away, and shaking being felt over a distance of 500,000 km (190,000 sq mi). In Iowa, some wells reported water level fluctuations of up to 1.42 ft (0.43 m). 335:
occurs at a rate of 5.3 cm (2.1 in) annually. The earthquake accommodated around 30 percent of the accumulated stress in the area since the 1899 events. A possible seismic gap exists between the western extent of the 1979 and eastern end of the 1964 earthquake ruptures.
