Abstract
The geothermal energy within the summit dome at the altitude of 2,100 to 2,455 m of the Yakedake volcano is calculated to be about 2.5 x 10/17 J. which represents a power output of 300 MWt, averaged over 30 years. The temperatures of solfatara in the northern summit dome at the altitude of 2,240 to 2,270 m range from 66.9 to 92.8° as of Oct, 1989. From an investigation of the thermal process in the volcano, it may be inferred that direction of heat energy flow from the Yakedake volcano magma body will be coincident with that of water flow in the river system from the summit dome.
