| Outline of Final Research Achievements |
Mt. Ontake and Mt. Kusatsu Shirane were suddenly erupted in recent years and many people were died. The objective of this research is to develope a continuous measurement observation telemeter system, which could detect trace amounts of volcanic gases such as hydrogen sulfide and sulfur dioxide at ppb level in preparation for the large eruption of Mt. Fuji. Volcanic gases were not detected at the top of Mt. Fuji during summer in 2017, but a trace amount of hydrogen sulfide was detected at Hoei's crater during summer in 2016 and 2017. We built a volcanic gas early detection telemeter system at Tarobo (1300 m), which is located at the foot of Mt. Fuji on Gotemba trail. Hydrogen sulfide has not been detected from 2016. Sulfur dioxide was usually not detected, but peaks reaching several ppb were sometimes detected. At that time, it was thought that smoke from domestic volcanoes such as Mt. Ontake and Mt. Asama were transported to Mt. Fuji.
