摘      要：Tecto nic stresses of Ce ntral Asia(limited by geographic coo rdinates 36-46°N,56-76°E)over the rece nt times are modeled based on moment elasticity,taking into account the focal mechanism of *** results obtained by the method of boundary integral *** relief of the earth’s surface,built on the map of Central Asia used to verify the solution of the inverse elasticity *** moment elasticity equations are simplified by assumingωk=εijkμi,j,which makes it possible to return to classical theory of elasticity,with the difference that the stress tensor ceases to be symmetricσij≠σ*** on the specifics of the geodynamic formulation of problems,the three-dimensional model reduced to a two-dimensional model for averaged stresses and *** to the results,a displacement field was constructed,which is fully consistent with the movements of the earth’s surface,established by the GPS *** model makes it possible to determine stresses variations in the region from earthquakes occurring in Central Asia.
