Abstract
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.
