In May 1998 huge landslides, triggered by rainfall in pyroclastic soils, killed 160 people and produced highly destructive effects in five small towns in the Campania Region (Southern Italy). After the disaster, the Civil Defence Department involved the University of Salerno in the scientific emergency management. In particular, the addressed questions dealt with: the residual risk evaluation in the flnwslide affected areas; the set up of an alarm system for the inhabitants safeguard; the drawing up of the guidelines for stabilization works aimed at the final consolidation of the zones at risk. In order to answer these questions, preliminary geological analyses were carried out so that it was possible, after only eleven days, to provide a mapping of the “residual risk zone” and to fix an alarm rainfall threshold for people evacuation. The guidelines for hazard mitigation measures were established over the 45 days following. After the initial stages of the emergency,
further investigation and analyses were performed, also thanks to the contribution of a territorial Survey Group, in order to improve the support to the Civil Defence Department. The activities of the emergency phase and the knowledge subsequently acquired are discussed in the present paper.
