ABSTRACT
The interest to high-frequency microtremors is supported by the possibility of obtaining useful information about geodynamic processes occurring in the Earth’s crust, as well as structural and other properties of the medium (Gordeev et al. 1991; Smirnov et al. 1991, Spivak 1998). Geophysics has established, though it is far not unequivocal, links between microseismic fluctuations and the geological structure of environment. Studying the nature of this interrelation is a fundamental problem. Its solution would allow to study the structure of rock massifs through the character of microtremor display. By «microtremors» we mean all kinds of natural and man-caused high-frequency (0.1-40 Hz) microseismic fluctuations: microseismic noise of different nature, pulse fluctuations, etc.
