Integrating Geoscience, Ethics, and Community Resilience: Lessons from the Etna 2018 Earthquake

Mount Etna has a well-documented history of frequent eruptions and seismic activity, periodically causing significant damage to urban areas. On 26 December 2018, a Mw 4.9 shallow earthquake struck the volcano’s eastern flank, severely damaging approximately 3000 buildings. The post-earthquake recovery strategy aimed to enhance community resilience by addressing the hazardous nature of the affected territory. This objective was achieved through measures such as relocation and public use transformation. In areas impacted by active faults, the relocation of damaged buildings was encouraged, while cleared zones were repurposed for public use, transformed into gardens and open-air parking spaces. Despite these efforts, some relocated individuals experienced psychological distress. To address this challenge, government planners played a pivotal role in disseminating scientifically accurate information, raising public awareness, and facilitating adaptation. The approach implemented on Etna was later adopted in other post-earthquake recovery programs in Italy, evolving into a replicable strategy for risk mitigation in disaster-prone areas.
