The red arrow shows the location of the landslide, and the yellow arrow shows the location of the high point of the wave sweeping over the headland.

Historically, tsunamis generated by earthquakes in Alaska have caused damage and loss of life along the West Coast and across the Pacific Ocean. Here in Alaska, tsunamis generated by nearby earthquakes or landslides represent “near-field” hazards.

The tallest wave ever recorded was a local tsunami, triggered by an earthquake and rockfall, in Lituya Bay, Alaska on July 9, 1958. The wave crashed against the opposite shoreline and ran upslope to an elevation of 1720 feet, removing trees and vegetation the entire way.
