Аннотация: Computational technology is developed for numerical modeling of wave fields generated by the electromagnetic pulse source "Yenisei" in blocky-layered geological media. Mathematical models of soils and rocks taking into account visco-elasticity and plasticity are applied. Algorithms of numerical implementation of these models are constructed based on the method of two- cyclic splitting with respect to spatial variables and physical processes. Parallel software for multiprocessor computer systems of cluster architecture is developed. We applied this technology to the analysis of frequencies and amplitudes of waves generated in the near-surface soils, and showed that the source "Yenisei" possesses the required seismic parameters. Given contribution presents the results of computation of seismic efficiency of the electromagnetic pulse source as the ratio of the energy passing through the reflecting surface in the depth of layered massif to the energy of pulse effect on the surface. The applied method is based on the analysis of the Umov-Poynting vector field obtained by means of high-performance computations. The results show that, by the criterion of useful seismic energy, pulse sources are not inferior to sources of vibratory type.
