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.

这项研究明确了大阪平原绳文遗址极少的原因是南海​​地震的反复袭击。他们在绳纹海侵时代的助跑特征足够大，足以将他们淘汰。首先，我们利用大量钻孔数据和冲积沉积物的厚度，恢复了大阪湾古代海底地形。第二步是利用南海海槽地震模型进行海啸数值模拟。出于这种考虑，人们讨论了2011年东日本地震发生的可能性。此外，我们还利用了对面向太平洋的沿海低地海啸沉积物的钻孔数据的分析结果。因此，我们可以确定海啸考古学的开端。
