Tsunami damage and high-water line at Seward, Alaska

1964 (approx.)

Detailed Description

The tsunami waves in Seward, Alaska washed the snow from the lower slopes of the hillsides, and the height of the highest wave is marked by the sharp "snow line" on the hillside behind and just above the rooftop in the left center of the photo. A series of large tsunami waves were generated by sudden uplift of the sea floor beneath the continental shelf off south-central Alaska during the earthquake.
