Sažetak
In the Zagreb wider area the Medvednica submountain area is considered as a separate geotechnical macro-zone distinguished by a considerable density of unstable slopes and landslides. The mentioned zone is a densely constructed residential area.The respective zone is affected by the known hypocentre in the Medvednica massif in which the earthquakes with a magnitude M > 5,5 may be expected. In the last hundred years there were three earthquakes generated in the mentioned massif. The expected response of the slope to the seismic excitation defined by the adopted dynamic parameters can be reflected in two ways: -either as a total failure of the slope previously affected by slow sliding;-or as initial deformations of the slope. Both of these two ways open the access for other factors, meteorological and anthropogenic in particular. The gradation of these results is likely to point out to the necessity of slope zoning after the degree of stability and the relating slide risk.
