Abstract:

Frequency-of-occurrence curves for tsunami elevations in American Samoa were determined. The islands of Tutuila, Aunuu, Ofu, Olosega, and Tau were considered in the analysis. A catalog of historical tsunamis in the Samoan Islands was compiled. Historical data were used to determine a frequency-of-occurrence curve for Pago Pago Harbor on Tutuila. A hybrid finite-element numerical model was then used to extend the historical data at Pago Pago to allow frequency-of-occurrence curve to be determined throughout American Samoa. Author
