研究了神户附近ARIMA SPAR区的10口井的地下温度梯度，每口井的最浅深度为160米，最深处为300米。最低温度为73℃，最高温度为133℃。通过计算得出平均温度梯度为11.7℃/30m。根据地下各点温度的测量结果，绘制了120 m深度的等温图。发现在被50℃等温线包围的地区，存在温度高于50℃的地方，从而得出结论，在120米处，50℃等温线范围内的温度有望达到50℃以上，这一结论可能适用于整个Arima Spar地区。
The underground temperature gradients with reference to the ten wells bored at Arima spar district near Kobe were studied.Each well bored as deep as 160 meters at shallowest and 300 meters at deepest from the ground surface respectively. The temperatures were found to be 73°C. at lowest and 133°C, at highest.Average temperature gradient was found, from calculation, to be 11.7°C. per 30 m. depth.An isothermal map was made at the depth of 120 m., according to the measuring results of the underground temperature at each point.In consequence, it was found that in the area surrounded by the 50°C. isothermal contour there existed places where the temperatures were higher than 50°C. so that the author attained the conclusion that temperatures above 50°C. will be expected in the area within the 50°C. thermal contour at the depth of 120 m. This conclusion will probably be applicable to the whole Arima spar district as far as the isothermal map concerns.
