Detailed Description
Damage from seismic sea wave aka Tsunami in Seward, Alaska. The waves came in from the sea via Resurrection Bay in the background. 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. The uplift "mounded" the overlying water, initiating a vertical oscillation of the water surface that dissipated as a series of radiating surface waves that struck the Alaskan coast at intervals of about 3/4 to 1 1/2 hours for about 10 hours after the earthquake.
