Abstract
Numerical simulations of blast wave generation and its propagation over a real terrain have been carried out. Based on the numerical results, more specifically the maximum overpressure distribution on the ground surface, a hazard map of blast wave damages was created for a fictitious eruption of Mt. Fuji. It demonstrates the usefulness of numerical simulations for establishing safety measures against volcanic hazards. Numerical simulations for investigating the generation of pyroclastic surge are also carried out.
