Fig. 2. Monitoring results: (a) sliding surfaces identified by inclinometric measurements; (b) minimum and maximum levels of the water table monitored by piezometers; (c) horizontal displacements measured by inclinometers G1 and G2; (d) horizontal displacements measured by inclinometers G5, G6, G7, and G8 (modified after Comegna et al., 2023).

Fig. 3. Climate data: (a) monthly precipitation, P 1 , and monthly average temperatures, T m ; (b) monthly value of the Cumulative Water Balance, CWB 1 (modified after Comegna et al., 2023).

In order to define a climate characterization of the area, we used the Italian gridded land-only SCIA-ISPRA dataset, corresponding to the national system for collecting and processing climate data managed by the Italian Institute for Environmental Protection and Research. This database, available at the web site www.scia.isprambiente.it, provides daily information about rainfall and temperature, at a spatial resolution of 10 km and 5 km respectively, after interpolating data collected from different local weather stations. Concerning the study area, Figure 3a shows the monthly values of cumulative precipitation, P 1 , and average temperatures, T m , in the study area for the thirty-year period from 1991 to 2020 obtained through the interpolation from four nearby meteorological stations (Agosta, Arsoli, Licenza and Licenza 2). Regarding P 1 values, they change between the minimum commonly monitored in August (4 168 mm, 49 mm on average) and the maximum in November (43-401 mm, 169 mm on average). Concerning T m values, they fluctuate between the minimum mostly detected in January (3-7 °C, 5 °C on average) and the maximum in August (20-26 °C, 23 °C on average). These data have been taken to calculate the monthly potential hydrological balance through the equation
