[MIS26-10] An examination of the impact of initial size distribution of volcanic ash particles on volcanic ash transport simulation in the case of Sinmoe-dake eruption 2011
Keywords:volcanic ash transport and dispersion model, Shinmoe-dake volcano, particle size distribution
For more improvement of the simulation result, the authors are examining the sensitivity of the resulted ash cloud distribution to another factor prescribed in the model; the initial size distribution of ash particles. As a preliminary result, it is found that doubling the variance of log-normal size distribution of ash particles improves the resulted ash cloud distribution. A systematic examination and its results on the impact of the initial size distribution on the ash transport simulation will be presented at the meeting.
