Abstract
The results of the numerical modeling of experimental concentrated atmospheric explosions, both nuclear and chemical, are presented. The surface pressure spectra are calculated and constraints are gained on their relation to the energy of surface seismic waves and to earthquake magnitudes. For a more accurate determination of the source parameters of the Tunguska event (June 30, 1908), atmospheric explosions at various altitudes and vertical falls of meteoroids are modeled numerically and their seismic effect is estimated.
