Experimental Landslide Monitoring Site of Poggio Baldi landslide (Santa Sofia, N-Apennine, Italy)

On 19th March 2010, a 4 million m3 landslide was re-activated in Poggio Baldi. The landslide severely damaged some private houses, a regional road and dammed the Bidente River. The landslide can be classified as a complex movement started as a rotational slide and then evolved into an earthflow. The 2010 event was a re-activation of an ancient landslide, whose previous catastrophic activation is dated back to March 1914. Starting from 2010, the landslide has been monitored by permanent inclinometers, piezometers and extensometers. Then, from 2015 an Experimental Landslide Monitoring Site has been developed mainly for research purposes and several multi-temporal surveys have been performed by using different remote sensing techniques, such as Terrestrial Laser Scanning (TLS), Global Positioning System (GPS), Unmanned Aerial Vehicles (UAV) Photogrammetry, Digital Image Correlation (DIC), Terrestrial Interferometric SAR (TInSAR). The Experimental Landslide Monitoring site demonstrated to be a great opportunity for both research and training purposes, as well as a place where monitoring instrument can be tested and calibrated.
