Sažetak
Dubrovnik, the Croatian and the world cultural monument of the highest category, that has been included in UNESCO's World Heritage List since 1979, is placed in seismic very active area. Throughout the history, the buildings in the city suffered a large amount of damage caused by natural disasters and by human action. The most critical of all these causes were earthquakes. Monitoring of the displacements in vertical direction in order to determine possible deformations of the historical centre of the Old City of Dubrovnik started with project network making in 1982. A comprehensive analysis of deformations has been made using PANDA scientific software. In 1995 and 1996 the larger Dubrovnik area was hit by more than 150 earthquakes of VII and VIII degrees on the MCS scale. Series of aftershocks that followed lasted for more than two years. In the course of this period more than 3000 earthquakes were registered. The region around Dubrovnik is very active in seismically-tectonic sense. The main cause of earthquakes are tectonic movements of the Adriatic micro-plate which pushes forward parts of the Adriatic structural unit. In this paper the report on geodetic measurements during the eighties and nineties in the past century will be made. The results of the analysis will show the need for further research, i.e. geodetic observations of the historical centre and much wider area around the city of Dubrovnik. Further observations must be expanded with the precise horizontal, GNSS and gravimetric measurements. The research should be done in an interdisciplinary way. The reconstruction plan for the previously established network, as well as the plan for the future research work will be presented in this paper.
