| Outline of Final Research Achievements |
We conducted observational tests for realizing potential difference measurements using UAVs (drones) to enable Magnetotelluric (MT) method observations in difficult-to-observe areas, such as volcanic summits. The initially planned potential difference measurement tests using large drones could not be realized due to significant obstacles caused by security issues, the COVID-19 pandemic, and the surge in UAV prices. On the other hands, we succeeded the observations using medium-sized UAVs, including flight, landing, and electrode placement. We also confirmed that potential difference data can be obtained using a simple installation method from the UAVs. Therefore, we believe that large UAVs will enable us to achieve our intended observations.

| Academic Significance and Societal Importance of the Research Achievements |
Mangetotelluric法は深部までの比抵抗構造を探査することができる唯一の手法であるものの、通常、観測点の設置には直接人が観測地に立ち入って電極等の設置を行う必要がある。これをUAVによって実現できることがほぼ示されたことは、人が立ち入ることが困難な場合が多い火山の山頂域等での研究を大きく進める可能性を示したことになる。さらに、本手法は地球外の惑星において電位差観測を行うための基礎的な情報も提供する。
