A seismo-acoustic study of Vulcanian eruptions

A seismo-acoustic study of Vulcanian eruptions
ブルカノ式噴火は，爆発的な表面現象，大振幅の爆発地震(噴火地震)，空気振動(空振)を励起する爆発過程の特徴が広く知られる噴火様式である．この爆発過程に引き続いて，連続的な火山灰放出が発生する連続噴煙過程に移行する場合も複数の火山で報告されている．ブルカノ式噴火は日本国内でも桜島や浅間山を筆頭に高頻度で発生しており，精力的な観測研究が行われてきたが，多く研究は爆発過程のみに着目している．ブルカノ式噴火の爆発過程から連続噴煙過程までの一連の噴火機構の理解を目指し，本研究は爆発過程の地震学的研究，連続噴煙過程での噴煙形成に伴う⻑周期空気振動の研究を行った．爆発地震に関する先行研究では，複数の火山で発生するブルカノ式噴火に共通，または異なる性質の存在が報告されている．地震波解析のみではなく，地殻変動や空振 ...
