Abstracts
The changes of side lengths between GNSS stations in CROPOS and the changes of their heights before, during and after the earthquake in Drežnica in 2013 are analysed in this paper. The earthquake with the epicentre in Drežnica was a small (slight) earthquake with the magnitude 4.6. It was one of the biggest earthquakes in Croatia ever since 2008 as the network of permanent GNSS stations was established. We have therefore decided to determine the size of terrain movements and whether previous GNSS signal could be noticed before the earthquake, and also the size of terrain movements after the earthquake. The measurements indicated that the coast in Senj was uplifted in the time of about twenty days before the earthquake in Drežnica, which might have predicted the occurrence of earthquake in a longer period. Two days before the earthquake in Drežnica, the terrain compression was also noticed that was rather small since the earthquake occurring after that was of a small magnitude. Up to same such results we obtained by the analysis of permanent GNSS of measurement in Kraljevo (Solarić, N. and Solarić, M. 2012), and too for the earthquake in the Skopje 2016 which we yet analyses. This research indicate that in the Croatia have sense organize the special service in CROPOS which will keep the change of earth's crust in areas with the stronger seismic activity. That refers to areas with the higher number of citizen such as Zagreb, area about nuclear power plant Krško, Dubrovnik, Split and Rijeka. All that can help seismotectonic researchers, that can eventually with other geophysical and new satellite methods (for example TwinSat) (the URL 4, URL 5, URL 6) more surely will announce one's arrival the possibility of earthquake.
