The article considers the modern deformation of Earth’s surface according to the results of the GNSS data analysis center of the MAO NAS of Ukraine in comparison with the latest lineament zones and faults, as well as, the Late Pliocene-Quaternary vertical movements of Earth’s crust. The areas of prevailing values of the compressiontension and the leftright rotation of Earth’s surface, the boundaries between which can be drawn in accordance with the latest lineament zones and faults, are identified. The areas of the prevailing stretching of Earth’s surface correspond to the zones of newest tectonic uplifts and the maximum amplitudes of the Pliocene-Quaternary movements and to the areas of the prevailing compression to the tectonic descents and minimum amplitudes. Four large modern geoblocks have been identified: the North-West and the North-East, which rotate clockwise, and the South-West and the South-East — counterclockwise. A qualitative mechanism for interconnecting the modern and newest movements of Earth’s crust is proposed.
