An 8.6 magnitude earthquake occurs in the Aleutian Islands of Alaska. Near the source of the earthquake, at Unimak Island, huge tsunami waves reached more than 100 feet above sea level and destroyed completely the newly built steel-reinforced concrete U.S. Coast Guard's Scotch Cap lighthouse; killing all 5 crew members.
The tsunami arrived 4.9 hours later in Hilo, causing $26 million (1946 dollars) in damages and killing 96 people. More
