Abstract
The article summarizes the available and newly collected data on the near-surface and deep structure and modern geodynamics of key regions of the northwest part of the Greater Caucasus. Models of the fault-block structure of this orogen and the nature of seismogenic displacements along the faults on its northwest pericline have been developed. The reasons for the abrupt change of the fold-block structure in the area of the Anapa seismogenerating flexural-fault zone are clarified. Detailed models of the near-surface and deep structure were constructed for a number of the most important seismogenerating structures in the Northwestern Caucasus that caused the Lower Kuban-II earthquake on November 9, 2002, with M = 4.7, and the Su-Psekh event on December 10, 2012, with Mw = 4.3, as well as the Pshekh earthquake on November 15, 2004 in Krasnodar krai with M = 4.6. Three-dimensional geodynamic and seismotectonic models of seismogenerating structures were constructed based on the results of field geological and geophysical surveys.
