a Changes in fumarolic gas outlet temperature. The horizontal broken line indicates the boiling temperature of water at fumarole altitude. b Changes in the H2O concentration of fumarolic gas. The red histograms in (a) and (b) indicate the monthly number of volcanic earthquakes observed by the JMA. The blue vertical solid line indicates the eruption at Ioyama volcano and blue vertical broken lines indicate eruptions at Shinmoedake volcano
