Abstract
The paper presents the results of generalization of geological, geophysical and seismotectonic materials. Deep structure of the crust and upper mantle is characterized by a series of different P-velocity levels, boundaries and capacities of petrophysical layers. Tectonics of the consolidated basement and its structural-material complexes, the structural features that influence localization of strong earthquakes data are summarized. Manifestations of tectonic movements and their intensity in different neotectonic areas are assessed. Structural-geophysical and structural-tectonic criteria for seismic hazard assessment for developing a regional seismotectonic model of the earthquake occurrence zones (seismic generating zones) are revealed according to the complex of geological-geophysical and seismological data. These data would constitute the basis for developing seismic zoning maps and seismic hazard assessment of the East Kazakhstan region.
