| Research Abstract |
In this study, it was made clear that the reason why Jomon ruins were very few in Osaka plain was due to repeated attacks of Nankai earthquakes. Their run-up characteristics in Jomon transgression age was enough large to wash out them. As the first step, we restored ancient bottom topography in Osaka bay with many boring data and thickness of alluvial accumulated sediment. And second step was numerical tsunami simulation with the model of Nankai trough earthquake. In this consideration, 2011 East Japan earthquakes were discussed to open the possibility of occurrence. Moreover, we used the analytical results of the boring data on tsunami deposit in lowland along the coast facing the Pacific. Consequently, we could establish the beginning of Tsunami Archeology.
