Abstract

The amplitude and frequency modulation observed in bottom pressure records of the 6 March 1988 Alaskan Bight tsunami are shown to be due to dispersion as predicted by linear wave theory. The simple wave model developed for comparison with the data is also consistent with an important qualitative feature of the sea floor displacement pattern which is predicted by a seismic fault plane deformation model, i.e. the existence of a western-subsidence/eastern-uplift dipole.
