Abstract

The observation of volcanic gas composition and continuous monitoring of the fumaloric temperature have been done at Kuchinoerabujima volcano since 1980. The activity of southern and western parts of the summit crater was increased from 2003. The concentration of sulfur dioxide and hydrogen gas is increased in volcanic gases. The calculated subsurface temperature from the gas composition is about 500℃. The temperature of volcanic gas is changed with the seismic activity and ground deformation. From the volcanic gas observation, the activity of Kuchinoerabujima volcano is clearly increased.
