Tsunami Map, Aleutian Islands Earthquake, 1957

The magnitude 9.1 Mw earthquake on March 9, 1957 south of the Andreanof Islands, Aleutian Islands, generated a tsunami that did severe damage on Adak Island. However, the most damage (about $5 million) was done in the Hawaiian Islands. There were two indirect fatalities, a reporter and a pilot, and injury to a photographer when their small chartered plane crashed in the ocean near Oahu. Map generated using Tsunami Travel Time (TTT) software: calculates first-arrival travel times on a grid for a tsunami generated at an earthquake epicenter. Map contours: 1 hour intervals: red 1-4 hour arrival times, yellow: 5-6 hour arrival times, green: 7-14 hour arrival times, blue: 15-21 hour arrival times. Maps were generated from earthquake epicenters in the NGDC Global Historical Tsunami Database using NGDC 2 Minute Gridded Global Relief Data bathymetry. Maps do not provide the height or the strength of the wave, only the arrival times.
