Research Abstract

Tatun volcanic group (TGV), located in northern Taiwan has few magmatic eruption and has intense geothermal activity. MT survey and chemical analysis of hot spring water around TVG indicates that extreme high conductive areas were found around Chih sing shan Volcano.This result suggests that magmatic gas is mainly supplied beneath Chih sing shan Volcano and expanded around TVG. The area size of high conductive zone is estimated more than 4 square kilometers, suggesting degassing in TVG might be comparable with that in Beppugeothermal area, which is typical geothermal activity dominant volcano.
