Peculiarities of the edge wave evolution a great distance away from the source are considered. It is shown that waveguide dispersion may result in discrimination of the region in a wave train corresponding to the Airy phase. The effect of the discrimination of the Airy wave in the remote zone for the model of a ‘step-like shelf’ is compared with real edge waves (using the marigrams of tsunami observed in the Sea of Japan in 1983).
