Outline of Final Research Achievements

Development of volcanic plume measurement technique especially for volcanic gas using a tethered He-baloon is the main target of this study. In order to establish the technique, a miniturized and lightened sulfur dioxide and hydrogen sulfide sensor system was made and tested with a tehered He-balloon for ash laden plume at Aso volcano, Japan, during the eruptive period. The knowledge and technique developed in this study, can be used not only for the tethered He-balloon measurement but also can be applied for volcanic plume monitoring using an unmanned aerial vehicle which is rapidly evolving.
