| Abstract: | Very few data on heat flow are available in the area around the aseismic front of the Japanese Islands. In order to remedy this situation, measurements of the terrestrial heat flow were made at three locations in the eastern part of Fukushima Prefecture, northeastern Honshu, Japan. The observed values of heat flow were 37 mW/m2 (0.88 μcal/cm2·s) at Soma, 52 mW/m2 (1.25 μcal/cm2·s) at Kashima and 19 mW/m2 (0.46 μcal/cm2·s) at Naraha, respectively. These data partially fill the gaps in the terrestrial heat flow data on land in northeastern Honshu, Japan. These values are considerably lower than the average heat flow over the world, but agree well with the previous estimation for the area. |
