Outline of Final Research Achievements

We developed an automatic Multi-GAS, which start by itself by detecting increase of volcanic gas concentration in the air, in order to realize volcanic gas composition observation at Sakurajima volcano where access to the summit is quite difficult. We also developed a method of Cessna-borne volcanic plume measurement observation with an Multi-GAS. By applying these methods, we characterized volcanic gas composition of Sakurajima volcano and quantify volcanic gas composition difference during normal degassing and continuous ash emission stages. Based on continuous and repeated volcanic gas observation at Asama and Miyakejima volcanoes, we did not found significant volcanic gas composition changes regardless of changes in volcanic gas emission rate and interpreted a constant temperature and pressure condition of magma degassing. At Miyakejima volcano, the observed changed in the volcanic gas composition was attributed to the changes in interaction with shallow aquifer.
