Abstract

Solve the inverse problem, which is aimed at modeling a discrete frequency spectrum of seismic body waves generated by artificially weak point explosion or a natural earthquake (M ≤ 4). Proposed a spherical model of the hollow area of the point explosion and used a well-known analytical method for modeling the hydro-mechanical oscillations of a liquid drop. Innovation in the  applied work is the use of a complete solution of the radial Euler equation. Such a modification of the classical scheme, which uses only an internal solution is mathematically quite correct, because it means virtuality  of seismic source’s elastic oscilation. As a result, with the help of the discrete spectrum of seismic body waves can be determined the linear parameters and total energy of  point explosion (weak earthquake) that is  approximated as a hollow body  with  spherical shape.
