The demise of Scotch Cap lighthouse

The earthquake was giant, at least magnitude 8.1. The tsunami that resulted killed 159 people in Hawaii, drowned a swimmer in Santa Cruz, banged up fishing boats in Chile and wrecked a hut on Antarctica. The curve of the Aleutians protected much of Alaska, but the five men at Scotch Cap had no chance.
