Abstract
The geothermal energy within the summit dome at the altitude of 1,800 to 2,455 m of the Yakedake volcano (alt. 2,455 m), Gifu-Nagano, Japan is calculated to be about 2.4 x 10/18 J, which represents a thermal power output of 2,500 MW, averaged over 30 years. The temperatures of solfatara in the northern summit dome at the altitude of 2,240 to 2,270 m ranged from 67.1 to 92.4°C in Oct., 1991. The water sample from a crater pond, Terugaike, on the summit showed pH and electrical conductivity of 4.38 and 42.2 s/cm in Oct., 1991. The geothermal energy within the parasitic volcano, Iwodake summit dome at the altitudes of 2,100 to 2,140 m is calculated to be 1.9 x 10/15 J which represents a power out of 2.0 MW over 30 years.
