| Outline of Final Research Achievements |
In active volcanoes, it is extremely important for volcanic disaster prevention to increase the accuracy of the eruption forcasting by elucidating the physical processes in the volcanic conduit along which magma ascends from deep reservoir to the ground surface.
However, it is difficult for researchers to approach the active volcanic vent and to pursue observations because of the danger of eruptions. Therefore, we developed a volcano observation system based on an autonomous unmanned helicopter. In that system, it is possible to remotely control the image taking from the air, data collection such as magnetic fields, installation of observation devices such as seismographs, sampling of volcanic ash etc. We have improved and advanced the observation method by using active volcanoes, such as Sakurajima, Kirishima, Kuchinoerabujima and Nishinoshima, as the main experiment sites.
