| Outline of Final Research Achievements |
In this study, a numerical model of conduit flow dynamics was developed in order to reproduce a transition from effusive to explosive eruptions which is a key process for eruption forecasting and disaster mitigation. Furthermore, a numerical model for calculating crustal deformation around the conduit system was developed, which is useful for detecting the eruption transition from geodetic observations. Combining the above two models enabled us to obtain the quantitative relationship between the conduit flow and the crustal deformation, leading to the understanding of the transition mechanism and conditions.
