In the spring of 2006, a large failure started moving in the Montaguto municipality, Campania, southern Italy, 40 km ENE of Benevento and 35 km SW of Foggia. The movement was a partial reactivation of an older mass movement in the same general area. In April 2010, the earthflow reached the Cervaro River valley, advancing at a maximum rate of approximately 5 m•day-1.
The earthflow damaged the SP90 provincial road and covered approximately 300 m of the national railroad that connects Naples to Foggia. The traffic along the railroad and the road was interrupted for about three months causing severe problems for the residents, the local economy, and the national railway system. The consequences extended throughout southern and central Italy. The Italian national Civil Protection Department led a large-scale effort to mitigate the effects of the moving landslide, re-open the railway, and re-construct the provincial road.

The GMG, on behalf of the CNR IRPI, worked to study the landslide’s evolution employing a monitoring system in near-real-time (three Robotic Total Stations and a multiparametric meteorological station) and performing a comparative analysis of a set of DTMs available from 2006 on.
These activities allowed to describe the recent evolution of the phenomenon and the characterization of its present activity, also taking into account the variation of the boundary conditions and defining the cause-effect relationship between precipitation and reactivation of the phenomenon.
