Relief is one of the sources of information about neotectonic activity. Using structural-geomorphological analysis, it is possible to identify weak zones, which often reflect hidden low-amplitude faults and fracture zones under the surface of Quaternary deposits. Using structural-geomorphological analysis, planation surfaces were identified, displacement amplitudes along faults and the magnitude of neotectonic movements were determined for certain periods of time. The results obtained were compared with seismicity and the degree of inheritance was revealed. 3D computer geological modeling of the stress state also helps in identifying zones of increased neotectonic activity, as the most dangerous zones in terms of seismicity. The stress state and directions of the compression axes in the horizontal plane were calculated using the RMS Roxar software. Also, for a more detailed study of the latest geodynamics of the Abinsk segment, the frequencies of earthquakes and the amount of seismic energy released were analyzed, and frequency graphs were plotted. When comparing the growth deformations of neotectonic uplift structures and the values of the latest stress state with seismicity, their significant correlation was revealed.

Nuclear power plants are sources of a large amount of electrical energy. Therefore, ensuring their safety is a priority for the successful development of nuclear energy engineering. When studying the relief using structural and geomorphological analysis, alignment surfaces and weak zones were revealed, some of which have been transferred to the rank of low-amplitude faults. These faults and the surfaces of the foundation and relief make the framework of a 3D model created using the Roxar RMS 2013 software. The model is given a certain geodynamic setting. As a result, parameters were obtained to make it possible to determine that the Novovoronezh nuclear power plant is located in an unsafe area from the viewpoint of neogeodynamics, unlike the Kursk and Smolensk ones. The geodynamic conditions within a radius of 150 km around the plants are also interpreted using modeling, and the kinematics of faults are described.
