Catastrophic waves (tsunamis) generated by the 7.4 magnitude earthquake in the Aleutian Islands engulfed the Hawaiian Islands. The maximum rise of water was as much as 17 m on the Island of Hawaii. The tsunami cost the islands 159 lives and $26 million in property damage (1946 dollars). This picture taken near Hilo, Hawaii, shows a bore advancing up the Wailuku River past the railroad bridge. The water rose about 5.1 m at the mouth of the Wailuku River. A steel span of the railroad bridge was torn from its foundation and tossed 273 m upstream by an earlier wave.
