Abstract
In addition to geological, tectonic, geomorphological, geophysical, meteorological, hydrogeological factors, the development of landslide processes and their activation in space and time are also influenced by the modern vertical and horizontal movements of the earth's crust. They can be monitored according to GNSS stations, whose network is developing intensively in Ukraine. The time series of vertical and horizontal geodynamic displacements on the example of GNSS data of stations “Uzhhorod” and “Lviv”, located in different geodynamic conditions, are analyzed. Correlation analysis of the interconnection of time series of displacements by different vectors between the indicated stations is done. With the help of the apparatus of mathematical statistics - correlation and spectral analysis, periodic patterns were detected in the specified time series, in particular, the expected 12-month periodicity in the displacement of time series was found, wh i ch is obviously due to meteoclimatic factors. In order to determine the influence of meteoclimatic factors in the long run, a correlation analysis between meteoclimatic factors and vertical and horizontal displacements has been carried out
