Seismic resilience-based strategies for prioritization of interventions on a subregional area

Abstract

The study focuses on seismic resilience at a sub-regional level and its effect on proactive planning of seismic strengthening. The case study for application is the sub-regional community of Agri Valley in Southern Italy. A resilience priority index is proposed and quantified, to determine the priority ranking of communities requiring retrofit interventions. In this study, the role of residential building stock is emphasized, since as this paper shows, it can strongly affect community resilience and mitigation strategies. The analysis presented in the study is only seemingly simplistic. In reality, its goal is to provide simple tools that are easy to apply. In this way, the study could improve mid and long-term resilience through the implementation of financially sustainable mitigation strategies based on a multidisciplinary approach. It considers a quantitative approach to resilience and combines the latter with socio-economic data in order to set priorities in the large-scale application of seismic risk mitigation strategies. The resilience values of the considered housing systems are calculated and are integrated with the processed economic and social data in order to prioritize retrofit interventions in the study area.
