Study of modern movements of the Earth's crust The Kola Peninsula and Karelia according to satellite observations

Abstract

Issues of safety of operation of subsoil use objects are one of the most important tasks of engineering geology. Thanks to the development of satellite geodesy technologies, it became possible to obtain data on the current movements of the earth's crust at different scale levels with sub-centimeter accuracy. The article is devoted to the issues of deformation monitoring of the Kola Peninsula and Karelia. There are many industrial enterprises in this area. Mining has a man-made impact on the earth's crust, which must be monitored. The purpose of the study is to study the horizontal movements of the earth's crust of the territory under consideration. Thanks to constant observations at various satellite stations, their speeds of movement were obtained. The results of satellite observations were processed using the Elcut program. As a result of processing by the finite element method, displacement vectors, strain tensors and a color scheme of horizontal displacements were obtained.
