AB: The theoretical and experimental fundamentals of the monitoring system of living volcanoes with the use of powerful vibroseismic sources are presented. A method to calculate Green's function for inhomogeneous models of media with the employment of the reciprocity principle was developed for the numerical modeling of arbitrary structures, in particular, magma chambers. The medium is assumed to be consisting of arbitrary blocks. Some part of the medium can be a layered pack with an arbitrary number of layers. The thickness of the layers and the velocity parameters of the media can be arbitrary quantities in both the layered pack and the block medium. It should be noted that the calculation of Green's function allows simultaneous calculation of the wave fields for an arbitrary number of sources and receivers. This is important also for problems of area seismic prospecting and for solving inverse problems of geophysics by using optimization methods. The results of first experimental works for the Taman mud volcano province are presented. The medium's model in the mud volcano Shugo region obtained on the basis of vibroseismic sounding data was refined by numerical modeling.
