Sažetak (engleski)

The Kostanjek landslide is the largest landslide in the Republic of Croatia. It is a reactivated deep-seated
translational landslide located in the urbanized area of the City of Zagreb at the base of the southwestern slopes of
Medvednica Mt. (Fig. 4). The sliding surface is developed in Sarmatian laminated marl, characterized by
alternation of very thin light and dark laminae known as varves (according to WEINHEIMER & BIONDI, 2003).
Displaced mass above the Sarmatian sediments consist of Lower Pannonian clayey marls with thin limestone
layers and Upper Pannonian massive clayey marls. The width of the displaced mass is 960 m, and the total length
of the Kostanjek landslide is 1.26 km. The maximal depth of the sliding surface is 90 m, according to
interpretation of ORTOLAN & PLEŠKO (1992). The total landslide area is approximately 1 km2, and the volume
of the sliding mass is evaluated to be 32 × 106 m3 (STANIĆ & NONVEILLER, 1996). Since its activation in
1963, Kostanjek landslide has caused substantial damage to buildings and infrastructure in the residential (Fig. 5)
and in industrial zones. The deep-seated landslide was caused by anthropogenic factors, mainly by excavations in
a marl quarry placed in the toe part of the landslide (Fig. 6). Uncontrolled blasting during the 1960s and 1970s in
the marl quarry and the limestone quarry, placed approximately 1 km to the north from the upper part of the
landslide, were also important destabilizing factors. Surface deformations are mostly expressed as ductile
deformations with rare opening of cracks, even at the landslide boundaries. Despite extremely slow to slow
landslide movements for 52 years, the risk in the area of the Kostanjek landslide is very high for residential
properties (approximately 300 single-family houses and infrastructure networks are placed on the moving
landslide mass).
