## 3 Geological Data Interpretation
This causes the compression of space and reversal movements of larger and local structures and emphasizes the tectonically and even seismotectionically most active sections of the faults. Of course, spatially negative movements show the lowering of parts of the structures. Most commonly, they appear in the footwalls of the tectonically most active sections of the faults. This is particularly evident along specific faults between Zadar and Dubrovnik and around Rijeka and in some places in the Pannonian Basin. Spatial positive movements represent elevated parts of the recent structural setting. In the area covered, the vertical movement angles are greater than 30\({}^{\circ}\), and in some places even higher than 60\({}^{\circ}\). It is probable that the latter movement angles are also present along larger geological structures where there are no geodetic points, e.g., along the area of the Adriatic (A) and Dinaric (D) and the western part of the Pannonian Basin (WPB) near

Zagreb. Sudden changes in the inclination angles are pointed out on tectonically very active sections of the faults around Dubrovnik, Split, Rijeka, Zagreb, and Osijek. A good example of the change in the angle of the movement direction measured at the geodetic points can be found in Dubrovnik (Figure 5b). Negative movement directions have been established at the DUBM and DUBR stations. They are found in the footwall of the main branch (4b) of the Moser-Biokovo-Dubrovnik fault (4a). At the DUBI and DUB2 stations, the movement direction reaches almost 50\({}^{\circ}\). This is a sure sign of the space compression, reverse elevation of the local structure of Mt. Srd, and recent tectonic activity on the broader Moser-Biokovo-Dubrovnik fault zone (4a,b).

Legend: 1—directions of annual velocity at geodetic points in mm/yr; 2—spatially positive movements (uplift) greater than 0\({}^{\circ}\), 20\({}^{\circ}\), 30\({}^{\circ}\), and 60\({}^{\circ}\); 3—spatially negative movements (descending) greater than 0\({}^{\circ}\), \(-\)30\({}^{\circ}\); 4—maximum and minimum slope angles.

Legend: 1—directions and slope angles of annual velocity at points DUBM, DUBR, DUBI, and DUB2; 2—faults with an indication of reverse movement; 3—main branch of Moser-Biokovo–Dubrovnik fault (4b); 4—layers of predominantly Cretaceous carbonate sediments. Figure 6a shows the obtained directions of movement velocities at geodetic points in Croatia, and due to the possible correlation of data, also in parts of Italy and Slovenia. The abundance of data in Italy is highlighted, which are shown separately in Figure 6b [2] ([PERSON] et al., 2017). A significant coincidence of the movement directions of geodetic points in Italy, and especially in most of the regional structural unit Adriatik (A in Figure 1) and the neighbouring parts of the Dinarides (D), is immediately noticeable. Movements towards NE and NNE prevail. Deviations towards the N and NNW are located around Rijeka, in parts of Istria and along the edge of the Alps.
