| Research Abstract |
This research proposed large volcanic eruptions such as forming caldera are prepared in 'Geothermal activity Dominant volcanoes', because magma stagnates beneath volcanoes and maintains geothermal activity. Magma degassing is one of the important factors to control magma stagnation, and found significant wide area of high conductive zone around GD volcanoes. Analysis of chemical components and isotopic data of hot springs detected dehydrated fluid from subducting oceanic plate, indicating magmatic contribution.
