Abstract

The article highlights the results of the first GPS measurements carried out along a geodetic profile that intersects all major geological structures in the Ossetian region of the Greater Caucasus. The interpretation of the measurement results was made in comparison with the results of neotectonic studies and data on the deep structure. The maximum decrease in the current transverse compression velocities was recorded in the region of the highest rise above the Earth's surface of a low-Q volume of the Earth's crust, which has a widening effect on the entire mountain structure. The presence of significant transverse displacements of the surface reflects the shear component along the largest faults of the Caucasian strike. The previously prognosticated significant decrease in the velocity of horizontal movements at the end of the aftershock process of the catastrophic Racha earthquake of 1991 on the southern slope of the Greater Caucasus was fully confirmed.
