The disruption or destruction of critical infrastructures (CIs) due to natural hazard events may have effects not only on the surrounding structures and environment, but also on the public health and safety, the economy, and the national security. Therefore, it is important for local and national governments to identify or develop efficient and strategic tools to manage and mitigate the risk and improve the resilience of these systems. The ST@STREST framework proposed in Deliverable 5.1 may represent the basis for the development of a new stress test concept that will support decision makers in the evaluation of strategies to not only reduce the risk but also to enhance the resilience of CIs against natural hazards. The time-evolution of community needs and the ability of the critical infrastructures to fulfil these needs is best represented and modelled using the concept of resilience rather than that of risk. In fact, the instantaneous loss by itself does not reveal how a community or society responds to a disaster. In this report the main aspects of a resilience-based stress test concept aimed at integrating the evolution in time of the performance of the CI in ST@STREST is introduced and discussed.
