In a seismic area of Ljubljana was micromesh Dobravica measured for the sixth time this year. It is designed to measure horizontal displacements and is the southest of three networks at Ljubljana's fault. This diploma presents some of the movements of the Earth's crust, Dobravica network description, instrumentation used for measurements in all series, reviews of results and the accuracy of measurements. Series were repeated from 1979 to 1995 in four-year intervals. In 2012 it was measured again to determine the horizontal displacement up to date according to the situation in 1995 and all other horizontal transport between series of measurements carried out in the past. This is determined by the differences in the coordinates of identical points with matching accuracy.
