INVESTIGATION OF TSUNAMI SOURCE OF THE 1498 MEIO TOKAI EARTHQUAKE FOCUSING ON THE TSUNAMI TRACE IN SURUGA BAY

Abstract

 Currently, the tsunami source caused by the Nankai Trough Earthquake has been announced, and the damage based on this source has been estimated and countermeasures are in progress. However, it is published that the tsunami trace of the 1498 Meio Tokai earthquake is higher than the current estimate. In order to revise countermeasures, it is important to clarify the generation and propagation of the tsunami. So I comfirmed the reproducibility using published models at first. As a result I estimated several local tsunami sources in Suruga Bay, and showed that a tsunami source of 20m to 43m is needed.
