Pyroclastic flow mitigation strategies: a new perspective for the red area

Mauro Iacuaniello, Andrea Montanino, Daniela De Gregorio, and Giulio Zuccaro

Abstract. This paper intends to show basic strategies and technical solutions that may reduce the consequence of a volcanic eruption on buildings. One of the most dangerous eruptive phenomena is pyroclastic flow, a gas-solid mixture which can flow slope down up to reach considerable distances from the point of emission, with a speed that can easily exceed 100 km/h (~30 m/s). The damage caused by the impact on buildings depends on the combination of several factors: the duration of phenomenon, the temperature of flow and the pressure produced by the impact. The study tries to define a design-oriented approach of retrofitting and new construction with specific reference to the possible eruption of Vesuvio or Campi Flegrei in the Campania Region of Italy. For both red areas, which are directly affected by the flows, the Department of Civil Protection defined only one solution, that is the preventive evacuation. Whilst through the proposed mitigation strategy, the task is to establish a resilient sector within the red areas where buildings can withstand pressure and temperature in order to achieve both economic benefits and make reconstruction easier.
