Outline of Final Research Achievements

The island-forming eruption at Nishinoshima volcano, Ogasawara Islands, Japan, started in November, 2013, lasting until July, 2018. The total volume of erupted lava exceeded one hundred million cubic meter, which is a recent biggest eruption in Japan. We conducted several remote sensing observations, a landing survey in October 2016, various types of geophysical observations, such as ocean bottom seismic and geomagnetic observations, seismic-acoustic observation in Nishinoshima, and operated a remote-island volcano monitoring system. This survey reveals the long-term eruption activity and the magma ascending process just before the eruption. The magma temperature was relatively higher than that of an ordinary island arc magma and the composition was a crystal-poor. The variation of magma composition suggests that andesite magma derived from a crystal-rich shallow reservoir and a crystal-poor deeper reservoir.

Academic Significance and Societal Importance of the Research Achievements

西之島の火山島形成プロセス,特にその噴火に至るマグマ上昇過程やマグマ供給システムの一端を,地球物理学的観測と物質科学的調査により明らかにしたことは,新たな火山島形成が世界的に見ても希な現象である事からも,学術的に高い意義を持っている.さらに,本研究において,Wave Gliderを用いた離島火山モニタリングシステム及び遠隔離島地震・空振観測装置が有効である事を示した事は,今後の海洋島の火山活動監視に新たな有力な観測手段を提供したものであり,火山防災上も意義の高い成果である.
