田辺・白浜における津波について

Abstract

This is a survey report on tsunamis in Tanabe and Shirahama. At first, a numerical modelis studied to know a specific property of a tsunami propagation with some consideration ofnumerical simulation to an observed big tsunami. In order to know any possibility of theforthcoming big tsunami, it is essential to learn the old documents and the tsunami catalogues.An application of stochastic process to the time history of the big tsunami leads to obtain aconvenient measure for tsunami warning and countermeasures, that is, in form of an exceedanceprobability for a given tsunami magnitude in a given time interval after applying a Poissonprocess to the local tsunami history in Tanabe and Shirahaina.
