Estimating the increased deformations areas that occur during the preparation of kamchatka earthquakes

The article is devoted to mathematical modeling of increased deformations areas of the Earth's crust that occur during the preparation of Kamchatka earthquakes. For this purpose, a generalization of the classical model of the Earth's crust co-seismic deformations, proposed by Yu. Okada, was made. The generalization is consisted in the introduction of increasing coefficients depending on the seismic efficiency. Based on the developed model, the deformation fields, that occurred during the preparation of two Kamchatka earthquakes, were simulated. It is shown that the areas of increased deformations extend hundreds of kilometers from the sources of upcoming earthquakes both on the surface of the Earth's crust and in its thickness.
