茨城沿岸における津波浸水想定区域調査

抄録

In this investigation, numerical simulation for tsunami inundation was performed by using a detailed topographical model along the Ibaraki Coast. As a result, products such as tsunami inundation maps, computer graphic animations, GIS data, etc. were made to be used by local governments for making tsunami hazard maps or promoting tsunami disaster prevention measures.
The tsunami source model of Empo Boso-oki earthquake was adjusted using tsunami run-up heights along the coast evaluated from damage rate of buildings at each village. Furthermore, characteristics of tsunami run-up along the river were examined by numerical simulation, which is carried out under both conditions that the river discharge exists or not.
