The contribution of electrical resistivity measurements to the analysis of landslide events

In order to gain insight into the study of natural avalanches dynamics, we illustrate a statistical model based on a dissipative dynamical variable associated to a position dependent factor of safety field. This model, as experimentally demonstrated, is able to reproduce the complex structure of landslide events, such as power-law distributions. In this paper, we introduce an explicit dependence of the safety factor on the electrical resistivity to simulate landslide events in pyroclastic soils. An application of the model to data acquired in a test area characterized by flowslide events (Monte Albino, Campania Region - South Italy) bear witness the relevant role played by the resistivity measurements in the landslide hazard assessment.
