Abstract

Modern technologies of satellite geodesy specifically related to the use of global navigation satellite systems allow reconstructing with high precision (of the order of several millimeters) modern relative displacements and velocities of the crust movements. It is known that such displacements are manifestations of the Earth geophysical activity. Major tasks of this research are the construction of mathematical models of deformation from satellite data and combined analysis of the obtained models of deformation and geophysical data on geotectonic activity by the example of Eurasia. Three foreign regions with different geological characteristics and located at different areas of Eurasian continent in Iran, China and Japan were taken as basis for detailed studies of concrete tectonic displacements and deformation calculations. Foreign territories were selected as major owing to availability of large arrays of regular observation data on coordinate variation for satellite stations located in those regions. In the studies of geophysical processes and block structure of Eurasia data on active faults collected and arranged by Yu. Gatinskii, Dr. of Geology and Mineralogy were used. To study the degree of kinematic dependence of individual blocks the data obtained in GPS observation stations of IGS networks of individual regional networks were used as well as laser observations SLR and Doppler satellite observations of DORIS system.
