| Abstract | The thermal process and-the geothermal energy in and around the Yakedake volcano, Gifu-Nagano, Japan are considered quantitatively. The hydrothermal activity is intense in the valleys at the western foot and the Nakanoyu area. The hot water flow is discharged mainly from the Gamada River geothermal area. The area under investigation is in a rugged section of the southern part of the Japan Alps Mountains. Yakedake is an active volcano with a lava dome, belonging to the Norikura volcanic zone, which is made up of a Quaternary biotite-bearing hypersthene hornblende andesite, The fumaroles in the summit dome areas of Yakedake and the parasitic volcano, Iwodake are active. |
