Summary

Thirty-eight new heat flow values, obtained mainly in the western part of the Sea of Japan, are presented. Together with 117 earlier values, these measurements establish a generally high heat flow in that area. The heat flow values range from 1.28 to 5.33 μcal/cm2 sec, and the average of 155 measurements is 2.22±0.53 (s.d.) μcal/cm2 sec. Heat flow is very high in the northeastern basin and the westernmost plateau, while an east-west zone crossing Yamato rise has relatively low heat flow. The high heat flow in the Sea of Japan is tentatively thought to be caused by hidden volcanic activity, but a more definite interpretation should be left for future study.
