This allows us to define the zones with major movement tendencies in Moravian territory. We chose one of the most anomalous and tectonically active areas, where the results of GNSS measurements in combination with earthquake data from the relevant period indicate increasing horizontal and vertical movement tendencies. This area is located at crossing
of the eastern marginal faults of the Bohemian Cretaceous Basin and the Boskovice Furrow, particularly its northern part.
The paper discusses and solves following problems: processing of all data obtained and offer a new interpretations of GPS results with the use of other geophysical and morphological information in the area where increased seismic activity appeared in the past,
interconnection and confrontation of MORAVA GPS data with CZEPOS and EPN networks, allowing further consideration of kinematic blocks located in the contact zone of the Bohemian Massif and Brunovistulicum, presentation of a credible vertical movement tendencies gained from repeated leveling measurement along the transverse profiles of the most risky zone in the study area.
Latest results from the new measurements in the MORAVA network supplemented by the results of repeated leveling permit detection of horizontal velocities of more than 1 mm / year, and local vertical variations up to several centimetres, which allows the inclusion of this area in the zones of increased risk.
