Four pyroclastic flow deposits (Hk-Kn, Hk-Km5,Hk-Km3,Hk-Km1) overflowed the caldera floor into the western slope of the old somma. AMS-^<14>C ages of charcoal fragments in Hk-Kn, Hk-Km5 and Hk-Km3 are obtained as ca.2.8ka, ca.7ka and ca. 22ka, respectively. Based on AMS-^<14>C dates and tephra-stratigraphy, this study revealed that Hk-Km5 distributes widely on the western slope of the old somma of the Hakone volcano., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 1996 (平成8)年度}, pages = {172--182}, title = {箱根古期外輪山西斜面に分布する中央火口丘起源の火砕流堆積物}, volume = {8}, year = {1997} }
