For this purpose, multi-station terrestrial laser scanner surveys were performed in 2015, 2016, 2017, and 2018. The aim of the study was to assess ground changes that occurred on the upper scarp from 2015 to 2018 and to infer a preliminary evolutionary model capable of supporting short-term landslide scenarios. This paper reports a study of the phenomena currently occurring on the 100-m high main scarp of this landslide complex. The landslide was classified as a rotational landslide, evolving into a partially confined flow-like landslide and causing the reactivation of the deposit of a previous landslide that took place in 1914. The Poggio Baldi landslide arose in the “Marnoso-Arenacea Romagnola” formation composed of a pelitic-arenaceous turbiditic sequence. The landslide caused severe damages to some homes and obstructed both the SS310 national road and the Bidente river. ![]() On 19 March 2010, a 4 million m 3 landslide occurred at Poggio Baldi, a small village in the Santa Sofia municipality, central Apennines (Forlì-Cesena, Italy). ![]()
