| Research Abstract |
Laboratory experiments investigating sound generation by bubble bursting in a non-Newtonian fluid have revealed memory effects of the fluid and feedback mechanisms controlling the waveform. Systems developed by this project were tried at Asama volcano and detected intermittent and continuous surface activities starting at the eruption of 2nd, Februaly, 2009.
