| Outline of Final Research Achievements |
Observation of volcanic gas composition is important for predicting changes in volcanic activity because it reflects changes in the temperature and pressure of magma and hydrothermal systems. In this study, we developed a compact and lightweight drone-mounted Multi-GAS to quickly observe volcanic gas composition during eruptions. The size of the Multi-GAS was 35 cm x 20 cm x 11 cm and 1.2 kg in weight and can be hung by the DJI Matrice 200 V2, a small industrial drone used in this study. We conducted test observations at Kirishima Iwoyama volcano using this device and obtained data equivalent to volcanic gas compositions measured simultaneously near the crater.

火山活動の推移予測のためには，活動が静穏な時から噴火時まで，切れ目なく火山観測を実施することが重要です．とくに，火山ガス組成は，地下の状況をダイレクトに判断できる観測項目ですが，噴火時には火口へ近づけないため，噴火時の観測は不十分な状況でした．本研究では，ドローンに搭載可能な小型軽量の火山ガス組成観測装置を開発しました．試験観測の結果，従来の大型な装置と遜色ない観測が実施できることを確認しました．今後，火山活動のモニタリングに活用していくことができるよう，整備・配備を進めていきます．
