In connection with the intensive development of the territory of the black sea coast of the Caucasus, advanced engineering geotectonic studies in detailed seismic zoning, as well as in the conduct of engineering and geological surveys for the construction of objects of increased responsibility, acquire the greatest relevance. In the course of seismotectonic studies within the Anapa-Gelendzhik section of the southern slope of the S-Z Caucasus, it was found that the foci of seismic events form visually distinguished linearly oriented zones (seismolineaments) characterized by a sub-vertical orientation. In plan, these zones most closely correspond to the latest structures expressed in relief, most of which are localized within transverse flexure-discontinuous zones, which appear to be deep and long-lived mantle structures. Construction of spatial-statistical models according to various criteria allowed to establish clustering of seismic events of the Anapa-Gelendzhik area by the value of their magnitudes, and clustering of points with low values was found. These clusters correspond to linear seismogenerating structures rather than morphostructural nodes.
