| Abstract |
Kuju Volcano area, in the central part of Kyushu island, Southwest Japan, is one of the most active geothermal area in Japan (Fig. 1). Kuju-Iwoyama, located northeastern part of the Mt.Hosshou, is an explosive crater of volcano and shows the most intense geothermal activity in this area. There are many active fumaroles, hot springs, and alteration zones. The purpose of this study is to make clear the subsurface structure of the volcano area where shows such intense geothermal manifestation by using geoelectromagnetic method. |
