We studied changes in the properties of the geologic environment in the vicinity of the stationary 40-ton vibration source at time intervals between the vibration sessions. Experiments have shown that the quantity of the energy released in the environment with time depends on the frequency of an amplitude spectrum. We introduced parameter α characterizing this dependence and have established a linear regular increase in its module between the series of switch-on of the vibration source during the field observations. A hypothesis is put forward that there are zones that can rapidly change their stressed state, both accumulating and giving the accumulated energy. Comparative analysis of the stressed state of the experimental zone showed significant differences in the spatial distribution of the gradient of a new parameter (β) before and after active low-frequency impacts on the geologic environment.
