Outline of Final Research Achievements |
To reduce the damage of the tsunami, it is important to examine the scale of a tsunami generated in the past in detail. The tsunami trace heights that is the information to presumption historical tsunami source is limited. But, in a source presumption only using the amount of tsunami trace, there is not the knowledge about the influence to give for the tsunami trace heights and the divided subfaults to have a big effect on the amount of tsunami in the presumed tsunami source. In wave source presumption only using the tsunami trace heights, I examined each appropriate analysis condition using combination optimization technique. As a result, clarify each appropriate analysis condition, which enable I could to suggest new wave source presumption technique for the historical tsunami.
