- Service:Field Investigations
Grmoščica Landslide in Zagreb extends over an area of 2.0 ha. The depth of slide is 5-9 m. The landslide toe is located just north of Ilica, while movements in the landslide caused lifting of the sidewalk, the north traffic lane and the best known and longest street in Zagreb.
