Mrs. Catherine Barsinas, 64, shows the researchers how far inland the 1946 tsunami inundated the island of Hiva Oa in the Marquesas.

Interview with Mrs. Catherine Barsinas, 64, a witness of the damage wrought on the Island of Hiva Oa by the large 1946 Aleutian tsunami. The witness has led the researchers along a road up a valley to the exact limit of inundation by the wave. The distance to the shore (328 m) and altitude (6.7 m) of this location were measured using surveying methods and entered into the database which will allow researchers to model the generation and propagation of the tsunami across the Pacific Ocean.

Driftwood deposited by the 1946 tsunami 412 meters from shore on the treeless Aleutian Island of Unimak.

Driftwood identified as watermark from inundation by 1946 tsunami on Unimak Island. On this treeless island, this stump was deposited at an altitude of 40 m, and a distance of 412 m from the shore (visible at far right).
