摘要：
In an approximation of the two-dimensional dynamics of a monodisperse collisionless gas suspension, the initial stage of explosive volcanic eruption is modeled. Plots of the amplitude of a shock wave versus the distance in the initial stage are constructed. The general picture of change in the dust concentration near a volcano crater is given. The dependence of the height of a gas-dust column on the explosion energy and the dynamics of ash ejection on volcanic eruption are investigated.
