The aim of this work is creation and practical testing of spatial migration model of dangerous endogenous geological processes. Analysis of existing approaches to the modeling of these processes is performed. The conclusion about the prospects of geodynamic risks mathematical models for the solution of this problem is drawn. Description of three-dimensional mathematical model of dangerous endogenous geological processes energy migration and related computational procedure are given, boundary conditions of its existence are formulated. Novelty and practical value of the model presented in the article are defined by variable thickness of model space, accounting of Mokho surface topography, spatial variability of elastic, viscous and density characteristics of geological environment, taking into account the Earth's surface curvature. It is shown that the trajectory of migration passes across those territories where sites of maximum horizontal and minimum vertical shift tensions concentrations are located. Besides, the conclusion is drawn that «stream» of endogenous geological energy with a high probability is passed from one deep level to another in conditions of «circulation» of horizontal shifts vectors in geological environment and increases of vertical shift tension. Results of mathematical modeling are adequate to really observed seismic and volcanic processes and phenomena.

Key words: modeling, energy migration, dangerous endogenous geological processes, horizontal and vertical displacements, geological medium, seismic and volcanic processes.
