Reconstruction of Underground Structure using Seismic Event Data

In big frame, the motivation of this paper is creation of a mathematical algorithm and package of programs for computer simulation of past earthquakes events, using seismic data, in order to reconstruct underground structure. Supposedly, this program package could be used also to process the data from seismic stations, obtained during some local explosions made on purpose. Taking into account, that this is multiyear and difficult task, in this paper we suppose to present main ideas and approaches for solving this problem.
