ASSESSMENT OF MODERN GEODYNAMICS OF AZERBAIJAN BY GPS MEASUREMENT DATA

Abstract

The article presents the methodology for calculating the velocity fields of modern horizontal displacements of the tectonic blocks in Azerbaijan, obtained from observations at 24 stationary GPS RSSC stations, a characteristic aspect of which is a noticeable horizontal displacement in the northeast direction at a speed of 5-18 mm / year. The velocities of joint seismic movement associated with earthquake events were investigated using the GAMIT kinematic positioning program for 2017 and 2018 years. Maps of horizontal velocities were built according to the data of the geodetic network of GPS stations of Azerbaijan for 2017 and 2018 years. An analysis of the data showed that the distribution of the velocities of horizontal displacements to the north and east is not constant, and the processes of shortening the surface of the Earth's crust in the study region are also not constant.
