Abstract
A cooling of heat source after the 1995 phreatic eruption of Kuju volcano is discussed based on the thermal, magnetic and gravimetric measurements. Thermal and magnetic measurements showed a quick cooling of the volcano. It is suggested that the cooling heat source is not a new intrusive magmatic body but a pre-existing hot rock beneath the central part of the volcano. Results of thermal and gravimetric measurements indicate that the cooling of the heat source is not by conduction but by circulation of meteoric water.
