Limit Equilibrium Analysis and Real-Time Monitoring as Support for Landslide Risk Mitigation: The San Rocco Case Study at San Benedetto Ullano (Calabria)

Abstract

With reference to landslides, Italy is exposed to the worst risk conditions among the industrialized countries (Guzzetti, 2000). In particular, the abundant and prolonged rains fallen in the 2008-2009 and 20092010 wet seasons triggered a great number of shallow and deep slope movements in Calabria (Southern Italy), mostly in the northernmost area. These geo-hydrological crises were so severe that the Italian government had to declare the “state of emergency” on both circumstances. Among the landslides activated in the mentioned wet periods, a largedebris slide threatened the southern suburbs of San Benedetto Ullano (SBU), a small village in the Cosenza province. In this paper, a brief description of the considered slope movement — that first mobilized on Jan. 28, 2009, and after a short period of inactivity, re-activated on Feb. 11, 2010 — is provided. In addition, the decision support system implemented following the first phases of activation is summarized. Based also on such system, the Authority of Civil Protection could effectively manage the geo-hydrological risk during the cited emergency phases.
