Landslide susceptibility maps in the rock slopes of the Ventotene Island (Latium, Italy).

The paper illustrates an application of the Matheson test, implemented in GIS environment, to the cliffs of the volcanic island of Ventotene (Pontine Archipelago, Italy). Starting from detailed field study and geo-structural analysis, four failure mechanisms were considered for the analysis (planar sliding, wedge failure, flexural toppling, and block toppling), and a susceptibility map was produced as a cartographic representation of the rock failures affecting the cliffs around the island.
