Observations of Modern Crustal Deformations in Moscow Using Global Navigation Satellite Systems

This article presents the results of processing observations of global navigation satellite systems (GNSS) at satellite-geodetic stations located in Moscow, including stations of the Sternberg Astronomical Institute (SAI) and the Faculty of Geography of Lomonosov Moscow State University (MSU). Horizontal velocities of stations are estimated in the International Terrestrial Reference Frame (ITRF2008) and fixed Eurasia (ITRF2008–EURA). The results show good data quality and consistent velocity of stations in the ITRF2008. The specificity of the calculated local velocities is due to the fault-block structure of the geological environment of Moscow. Anomalously high vertical velocities are detected on Vorobyovy Gory. Apparently, they are associated with the geodynamic features of the active landslide slope of Vorobyovy Gory, as well as with the proximity of the stations and reservoir of the Leninogorsk water distribution facility of the Mosvodokanal, which creates regular periodic loads on the soil.
