Sažetak
Paper presents 11 year long interdisciplinary research of geodynamic processes of the area of the City of Zagreb. The Geodynamic GPS-Network of the City of Zagreb represents the longest and the most intensive research effort in the 􀂿 eld of geodynamics in Croatia. Since the establishment of the Network in 1997, several series of precise GPS measurements have been conducted on specially stabilized points of Geodynamical Network of City of Zagreb with purpose of investigation of tectonic movements and related seismic activity of the wider area of the City of Zagreb. The Network has been densi􀂿 ed in 2005 in the most active region of northeastern Mount Medvednica. Since then, several GPS campaigns have been conducted. Processing of observation data was done with scienti􀂿 c software GAMIT/ GLOBK, developed by MIT. From this series of GPS measurements geodetic model of tectonic movements has been created. In the area of interest, independent geological investigations have been conducted through even longer period of time which resulted in geological model of tectonic movements. The correlation coef􀂿 cient between geodetic and geologic model has been calculated and shows high degree of correlation thus giving credibility to both methods of research. Systematic analysis has been conducted over geodetic and geologic results giving as a result unique interdisciplinary model of crust movements over wider Zagreb area. This interdisciplinary interpretation of obtained geodetic movements leads to a new scienti􀂿 c insight about geodynamics of the City of Zagreb area. The results of this scienti􀂿 c research will be used to delineate zones of potential earthquake hazard or tectonically caused landslides.
