Abstract

The article considers the monitoring results of long-term geodynamic observations, on the basis of which the concentration areas of elastic stresses and strains in the depositional sequence, displacement of geodetic coordinates of on the Earth’s surface, as well as the variations in electric and magnetic fields are studied. The authors analyzed the results of the magnetometric studies to identify the seismomagnetic effect and assessed the stress–strain behavior of seismogenic areas. To observe the changes in the Earth’s surface due to geodynamic processes, we used high-precision GPS measurements carried out using the differential method and the so-called GPS base stations. From the comparison of earthquake parameters and based on the geological model of the sedimentary cover with regard to the seismic data of the common depth point (CDP) method, we conclude that the earthquakes recorded in the Black Sea–Caspian region in 2006–2010 occurred on the border between the Mesozoic and Cenozoic levels and within the Cenozoic interval of the geological section. Degassing monitoring based on the geophysical observatories of mud volcanoes indicates that the gas regime and degassing in the region are closely related to the impact of modern geodynamics on the evolution of the surface and deep shells of the Earth, as well as on the accumulation of combustible minerals.

The studies were supported by the Ministry of Science and Higher Education of the Russian Federation under State Contract No. 075-00069-20-01 (the basic part of the state contract in the field of scientific activity).
