These earthquakes caused abrupt subsidence in Kochi Plain. The amount of the subsidence was 0.5-2.0m per one earthquake. I carried out some borings in the small lowland located at this subsided area. And samples obtained from these cores were analysed for FeS_2-S contents and ^<14>C dating. I recognized that the sea level had been on a little higher than -1.4 to -1.6m msl. in 5,500-6,000yr.B.P., had been -0.5m msl. in 3,800-4,100yr.B.P. and had been 0.3m msl. in 2,800yr.B.P. In this study, it was impossible to separate the tectonic component and glacial-isostatic one because of too little influence of crustal movement, through the attitude of the sea level in 6,000yr.B.P. deduced by Nakada et al. (1991) was 0-2m with removing the tectonic component., タンデトロン加速器質量分析計業境報告 Summaries of Researches Using AMS}, pages = {11--15}, title = {四国南部の溺れ谷低地における完新世後半の古海水準}, volume = {4}, year = {1993} }
