Research Abstract

During explosive volcanic eruptions, a mixture of volcanic ash and gases is ejected from the volcanic vent into the atmosphere. In this study, I have developed a 3-D numerical model of the eruption cloud dynamics and estimated the relationship between the explosive intensity and the column height and the column collapse condition. On the basis of the 3-D simulation results, I have suggested a simplified model which predicts the column height and the column collapse condition.
