摘要：通过测量基底岩石的导热系数，利用深钻孔穿透1995年兵库县南部地震期间激活的野岛断层，研究了日本西南部Awaji岛平林地区的大地热流。利用温度测井资料，得到平林县大地热流值为56.6±5.2 mW/m2。讨论了平林县兵库县南部地震余震切断深度与大地热流的关系。截止深度大致相当于300°C的等温线。
Abstract Terrestrial heat flow at Hirabayashi in Awaji Island, south‐west Japan, was investigated using the deep borehole penetrating through the Nojima Fault, which was activated during the 1995 Hyogo‐ken Nanbu earthquake, by measuring the thermal conductivity of basement rocks. Using the temperature logging data, the value of terrestrial heat flow in Hirabayashi was found to be 56.6 ± 5.2 mW/m2. The relationship between cut‐off depth of aftershocks of the Hyogo‐ken Nanbu earthquake in Hirabayashi and terrestrial heat flow are discussed. The cut‐off depth roughly corresponds to isotherms of 300°C.
