Field survey of the 1946 tsunami in the Marquesas: Interview of a
Nahoe, Hiva Oa, 31 July 2000.
Interviewing 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 us along the road up the 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 are then
measured using surveying methods, and become elements of the run-up
and inundation database which will allow us to model the generation
and propagation of the tsunami across the Pacific Ocean.
