Magic Foglio 53 Bari — Map (OpenData)

Sheet 53 presents the major recent landslide event of the southern Adriatic margin called Gondola’s landslide and its adjacent complex tectonic structure (deformation band of the Gondola fault). The Gondola landslide occurred about 20-24 thousand years ago during the last period of lowering the sea level. This event generally affects pre-existing sliding surfaces and represents a reactivation or retrogressive propagation. In many cases there is evidence of net escarpments that truncate stratified sedimentary deposits and connect on weakly inclined reflectors towards the sea, which can be interpreted as “levels of weakness”. These elements, in addition to the presence of old buried landslide bodies, define an area predisposed to long-term retrogressive instability. In view of the seismic activity and the presence of important deformative structures, such as the Gondola structure, which affect this margin, the possibility of a large-scale landslide event could lead to the potential generation of tsunamis on the South-Adriatic margin. There are 2 critical points related to tectonic structures and landslides. CNR-ISMAR.
