Abstract

Understanding the frequency and dynamics of a huge tsunami is crucial for designing disaster mitigation strategies. This study aims at analyzing the paleo tsunami through the inspection of physical properties of tsunami sediments in Tohoku. We conducted Optically Stimulated Luminescence (OSL) dating, C14 dating, particle analysis, and tsunami calculation. C14 dating and OSL dating proved that several tsunamis came to Tohoku in last 3000 years. OSL dating and particle analysis proved that the layer which has many coarse particles is suitable for OSL dating. Tsunami simulation and particle analysis proved that the coarse sediments deposit in intense flow and the fine sediments deposit in calm flow.
