Abstract
The paper considers the problem of velocity model reconstruction of an elastic medium in the problem of monitoring the zones of underground nuclear explosions. An approach based on solving a set of forward geophysical problems is considered. For the first method, a brief description of the method for numerical simulation of the full wave field is represented. Results of numerical experiments on modeling the medium with inclusion are also presented. Inclusion is an analogue of the cavern formed as a result of underground nuclear explosion. The software for creating 2D and 3D models of heterogeneous elastic media was developed. Theoretical results of experiments are presented.
