Abstract
This paper presents the results of experimental studies and numerical calculations of weather-dependent ecological risks to social infrastructure facilities from the effects of powerful infrasonic vibrations generated by man-made and natural explosions. The results were obtained by applying an original ecologically safe approach developed by the authors and involving the use of seismic vibrators as sources simulating explosions but having much less power compared to the explosions. Such sources generate both seismic and acoustic (seismoacoustic) vibrations with precision metrological power and frequency-time characteristics, which, in contrast to explosions, ensures high reproducibility of research results. Results comparable to explosions are achieved due to the energy accumulation of weak vibroseismoacoustic signals. The propagation of infralow-frequency wave fields is studied depending on weather conditions and taking into account the effect of heterogeneity of the atmosphere. The results of the experiments are compared with those of numerical calculations.
