Abstract
The relation between volcanic and geothermal activities in Kyushu will be discussed in terms of the activity index and radiometric ages of volcanic rocks distributed in and close to geothermal fields. The activity index is defined as the ratio of temperature measured in a well to the boiling temperature, and ranges from 0 to 100 (Hayashi, et al. (1981) GRC Transactions, 5, 177-179).
