However, identification technique of tsunami sediments is still uncertain. In particular, dating of tsunami sediments is indispensable to refer for hlstorical disaster events. In this study, a continuous soil sediments (SND7) were taken by geoslicer (Fukken co. ltd.) from Sendai Bay coast in northeast Japan. Plant residues were picked up from the SND7 geoslicer sample for radiocarbon dating. The radiocarbon measurements were performed by the Tandetron accelerator mass spectrometry system (Model-4130, HVEE) in Center for Chronological Research, Nagoya University. Total organic carbon content of the plant residues was 54.1 wt.% and stable carbon isotope ratios of the plant residues was -29.1 permil (vs.PDB), which consist with those of modern terrestrial C3 plants. In this study, the calibrated age of plant residues below the sandy sediments was 940-1060 cal BP (2\u03c3range), and the ages were agreed well with those of the Jogan earthquake and tsunami in the Sendai plain.
