The ligosullo (Ud, italy) landslide, revisiting of past data and prospects from monitoring activities

Abstract

The paper focuses on the analysis of a landslide, located in the northern sector of the Friuli Venezia-Giulia Region (North-Eastern Italy) affecting the village of Ligosullo. Field surveys, geophysical investigations and interferometric analyses, financed by the Geological Survey of Friuli Venezia-Giulia Region in the last 15 years let to recognize a sliding surface up to 70 m deep, causing the mobilization of 7 millions m3 of material. A new phase of studies including geological and geomechanical surveys andmonitoring activities has been recently undertaken by the University of Padua (Department of Geoscience) and NHAZCA S.r.l. (Spin-off of “Sapienza University of Rome”). The first results we obtained and the future goals are discussed in this paper. .
