Abstract

Over the past few decades the Campi Flegrei territorial system was interested by intense urban expansion overlooking the volcanic risk. In this active volcanic area, where a short period evacuation could be necessary, the emergency management cannot be based solely on the hazard related information, but the territorial and social features must be as well taken into account. In this framework, the main purpose of this research is to point out the seriousness of the present setting of Campi Flegrei territorial system in case an evacuation would become necessary. Following the concept of regional evacuation, the zone to be involved in emergency planning was identified as the whole of the area threatened by the volcanic events occurred in the last 10 ka. Inside this area the spatial relation between the residents distribution and the outflows of routes, railway stations and harbours, necessary to leave the dangerous area, was investigated. A spatial relational GIS-based procedure was used to draw the territorial system vulnerability map for evacuation, depicting the zones with different capability to support the evacuation of residents in case of renewal of volcanic activity. Basing on the concept that people could leave the dangerous area by the means of transport supplied by Civil Protection, and using the threshold value of over-crowding of 0,70 people/ m2, we identified the collection points for residents to be immediately evacuated in case of volcanic unrest, and five microzones displaying different capability to cope with an emergency phase.
