Abstract

A series of three-dimensional numerical simulations of imaginary volcanic eruptions was carried out. The numerical simulations take detailed terrain of the interested area into account. Based upon the database for the correlation of the blast wave strength and the degree of hazardous damage, hazard maps of the volcanic eruption were produced. Two different eruption models were tried to investigate the effect of the way how the energy is released on the degree of the damages. The usefulness of the current numerical simulation to establish the safety measures against eruptions of any particular volcanoes.
