Active monitoring technology in studying the interaction of geophysical fields

Abstract The problem of studying the interaction of various geophysical (seismic, acoustic, meteorological) fields is considered in the context of prediction of geoecological risks generated by technogenic and natural phenomena. It is proved that meteorological -dependent processes of propagation of infrasound from explosions in the atmosphere can greatly enhance the ecological loading on the social and natural environments. Such a situation is observed in regions of open strip mines, test sites, and other areas where regular explosions are made. Therefore the active vibrational method is proposed and investigated by the authors for the sounding of adjacent lithosphere–atmosphere media by strictly repeating small-power vibrational seismic and acoustic oscillations that powerful seismic vibrators can radiate. It is proved that simultaneous remote recording of both types of oscillations is possible. The use of the approach of active monitoring of the natural environment makes it possible to achieve ecological purity, high repeatability, and precision accuracy of the measurement parameters being estimated. The results of these works are illustrated by data from numerous experiments and numerical calculations.
