In particular, six monitoring devices are adopted: three “point” systems, made up
of a network of sensors that locally measures the start of shallow or deep
displacements, and three “area” systems that remotely measure the movement of large
slopes. All monitoring systems are fully integrated and connected to a unique data
transmission system.

The system includes both empirical and complete mathematical models for
landslide triggering. Empirical or hydrological models are simple relationships,
obtained by linking the antecedent rainfall and the occurrence time of landslide, while
complete models take into account the hydrological and geotechnical processes
involved in slope scale and affecting stability. Complete models, adopted in this
research, include local models and areal models.
