The Scotch Cap Lighthouse on Unimak Island, Alaska after the earthquake and tsunami. A magnitude 8.0 (Mw) earthquake with the source to the south of Unimak Island generated a tsunami that destroyed the five-story lighthouse, located 9.8 m above sea level. Only the foundation and part of the concrete sea wall remained. All five occupants were killed. The waves deposited debris as high as 35 m above the sea. Although little damage occurred in Alaska, except at Scotch Cap, the tsunami was one of the most destructive ever to occur in the Hawaiian Islands.
