Аnnotation: The paper shows the possibilities of complex morphometric analysis of the relief and computer modeling of modern geodynamics for identifying seismically active areas of two different regions that are well studied in seismotectonic terms the North-Western Caucasus and the Voronezh anteclise. At the quantitative level, the majority of earthquake epicenters are associated with areas of increased values of a number of morphometric characteristics of the relief (the depth of vertical dissection, the steepness of slopes, the density of lineaments and elongation lines, etc.). By the method of computer modeling, the areas of possible formation of new fractures are identified, within which 80 % and 65 % of the earthquake epicenters of the North-Western Caucasus and the Voronezh anteclise, respectively, are located. The shares of the area of these regions are 55 % (for the North-Western Caucasus) and 36 % (for the Voronezh anteclise), which indicates the informative nature of the results obtained. The significance of the conducted research lies in the fact that used methods and approaches can be in demand when outlining the proposed seismically active areas of territories where detailed seismological observations have not been carried out.
