Compilation of Eleven New Heat Flow Measurements on the Japanese Islands

Abstract

New land heat flow data at eleven localities in Japan are presented. There are four localities in the Tohoku District, one in the Kanto District, three in the Shikoku District, one in the Chugoku District and two. in the Kyushu District. The obtained heat flow values, varying from 1.28 HFU (1HFU=1O-6 cal/cm2 sec) to 21.6 HFU, (i.e. from 53.5 to 905mW/m2), are in general agreement with the previously estimated heat flow distribution in the area.日本での未発表の陸上地殻熱流量の値をまとめて報告する.測定地点は東北地方に4地点,関東地方に1地点,四国地方に3地点,中国地方に1地点,九州地方に2地点の合計11地点である.地殻熱流量の値は1.28HFU(1HFU=10-6 cal/cm2 sec)から21.6HFUまで(53.6mW/m2から905mW/m2まで)変化しているが,これまでに得られた地殻熱流量分布の傾向とほぼ一致している
