Risk assessment from debris flows in pyroclastic deposits along a motorway, Italy
Abstract. This paper contains a quantitative estimate of the risk to life along the A3 motorway, Naples–Salerno. It examines a 1 km long section of the route between the towns of Pagani and Nocera Inferiore which passes below the northern slope of the St. Pantaleone hill. During the 38 years between 1960 and 1997 there have been four debris flows which have claimed two casualties, as well as a large amount of damage and injuries and resulted in the motorway remaining closed to the traffic for a long time. The annual probability of death of at least one occupant of a vehicle was calculated using the "event tree" analysis. The following assumptions have been made: the death probability was calculated only for accidents caused by the direct impact of a moving vehicle with landslide debris; the chance that more than one person could be present in the car during an accident was not considered; it was assumed that traffic is uniformly distributed in time. Over the 38-year period considered, the annual probability of occurrence of one fatality in a single accident due to crashes into landslide debris defines the unacceptable risk Results suggest that countermeasures are needed to reduce the risk along the entire section prone to debris flows when considering high traffic intensity.
