Abstract: The need for scientific methodologies to assess quantitatively the resilience of critical infrastructures against natural hazards (like earthquakes, floods, storms, landslides and wildfires) during the last decade has become a relevant aspect for several countries and for the European Union. In fact, this quantification could allow setting and implementing effective measures to prevent or mitigate the negative socio-economic effects that a possible disruption of these infrastructures, caused by extreme natural events, could cause. This paper focuses, in particular, on energy corridors and proposes a new approach for evaluating their resilience, based on the definition of a criticality index able to estimate the economic damage associated to all the hazards by taking into account the spatial dimension of the infrastructure and by combining different interdependent parameters that could affect the criticality level. The procedure was tested by means of an application to a simplified case study. The obtained results highlighted the main advantages of the defined method, especially in ranking the critical sections of the infrastructure and prioritising the investments for reinforcing and protecting it or in identifying the further tests to be performed, especially in the case of a reassessment of the acceptable risk limit.
