SEISMIC MONITORING OF MODERN GEODYNAMIC PROCESSES USING A GRADIENT SYSTEM

The article discusses the methodological issues of registration of a seismic wavefield using a three-component gradient system and data processing aimed at revealing an endogenous seismic field. The processes of rock destruction cause seismic emission effects and create specific wave pictures of the elastic field in a deformable medium, which can be analyzed during geophysical monitoring. Revealing the endogenous sources of elastic waves using the proposed experiment allows us to observe the activation of the Tien Shan lithosphere. The authors provide an estimation of the energy characteristics of the seismic field generated by endogenous sources. A possible causal relationship between lunar-solar tides and the activation of endogenous sources is analyzed. The basics of the method for studying irreversible deformations by measuring the seismic field on the Earth’s surface using a gradient system have been developed. As an example, we used the data obtained at the Chon-Kurchak observation point of the Research Station of the Russian Academy of Sciences in Bishkek at the Bishkek Geodynamic Proving Ground.
