As volcanic hazards induce damage with their flows of gases, liquids, and solid materials, a numerical simulation using multi-phase formulation is applicable to the analysis and evaluation of the risks from these volcanic hazards in both normal and emergent periods. A numerical simulation can also be useful for crisis management. Quick and precise evaluation is needed for upcoming and ongoing hazards, and we present here a concept for the development of a volcanic hazard evaluation system for these hazards, a system in which an input parameter database is compiled and countermeasure information is provided by considering the exposure and vulnerability database.
