###### Abstract  
The Adriatic microplate has always attracted scientific attention, and various studies on the geodynamics of this area have been performed over the years. With the development of global navigation satellite system (GNSS) technology in the last 30 years, most significant research in this field has used it as the primary source of data on geodynamic movements. However, apart from a few global positioning system (GPS) campaigns conducted in the 1990s, the measurements had a low spatiotemporal density. Therefore, the eastern side of the Adria region or the territory of the Republic of Croatia was usually omitted from the results presented in the various published papers. A study of this literature concluded that the territory of Croatia represents a kind of scientific gap and that denser measurement data from GPS/GNSS stations could be used to supplement the geodynamic picture of the area in question. Thus, GPS/GNSS measurements from 83 stations (geodynamic, reference, and POS GPS/GNSS) all over Croatia and neighboring countries for a period of almost 20 years (1994-2013) were collected and processed with Bernese software to obtain a unique database of relative velocities. From the geological perspective, the most important and latest insights on the recent geological structural setting, tectonic movements, most active faults, and relationships and movements of structures were taken into account. It was important to compare the geodetic and geological data, observe the present tectonic dynamics of the geological structural setting, and determine the causes of the obtained directions of movement. The research presented in this paper, based on a combination of geodetic and geological data, was conducted to broaden the current knowledge of the present tectonic dynamics of the geological structural setting of the eastern part of the Adriatic region.

reference, and POS' GPS/GNSS stations) distributed over the territory of Croatia and neighbouring countries for a period of almost 20 years (1994-2013) were collected. By processing this data in the ADDNEQ2 program module of the scientific software Bernese 5.0 [4] for the central epoch of 15 January 2004 (e 2004.04), a unique database of the relative velocities for all 83 stations was obtained. Special attention was also given to the collection and analysis of geological data. In gathering the necessary data, the latest and most important insights on the recent geological structural setting, tectonic movements, most active faults, and relationships and movements of the structures were considered [5; 6; 7; 8; 9; 10; 11; 12; 13; 14; 15; 16; 17; 18; 19]. Some details were also collected during the study of the seismotectonic activity [7; 20; 21; 22; 23; 24; 25; 26; 27]. Particularly prominent were recent studies that directly addressed geodynamic processes [2; 3; 28; 29; 30; 31; 32; 33; 34; 35; 36; 37; 38; 39].  
The research presented in this paper was based on a combination of the abovementioned geodetic and geological data and aimed to broaden the current knowledge of the present tectonic dynamics of the geological structural setting of the eastern part of the Adriatic region.
