HORIZONTAL AND VERTICAL DISPLACEMENTS OF THE STATIONS WITHIN THE FRAME OF THE INDIVIDUAL PLATES BASED ON THE ITRS2000 REFERENCE SYSTEM

Global horizontal and vertical movements were computed for individual tectonic plates from the velocity vectors published for ITRS2000. For the stations within the frame of those plates the differences from the global displacements and their rms errors were then computed. Global vertical motion (expansion/compression) of the Earth if exists is lower 1 cm/year (with 66% probability) or 2.5 cm (with 95% probability). Global horizontal motion of individual plates was detected and model NUVEL-1A was corrected, but accuracy of the model does not allow to detect r esidual motions of individual stations lower 1 cm/year (with 95% probability) in most cases.
