Volcanic risk management, infrastructure monitoring and administrative simplification for the reduction of territorial and social vulnerability

Volcanic risk management in the Campi Flegrei area is based on a regulatory and operational framework defined at national and regional level aimed at mitigating the effects associated with bradyseismic phenomena and possible eruptive scenarios.

Zoning forms the basis for detailed planning, for the definition of regional accommodation capacities and for the preparation of interregional evacuation plans.

The monitoring system and alert levels entrusted to INGV provide data on seismicity, land deformations, geochemistry and thermal variations. Prime Ministerial Decree 3236/2025 updated the alert level system.

The Civil Protection Department introduced an updated operational strategy, aimed at improving the integration between scientific monitoring and decision-making; strengthening coordination between Campania, Prefectures, and Municipalities; standardizing risk communication procedures for the population and updating reference scenarios based on the evolution of bradyseism. The strategy also includes the adoption of simulation models for evacuation management and infrastructure vulnerability assessment.

The “Campi Flegrei decree” introduces urgent measures to address the effects of bradyseismic earthquakes and to strengthen structural prevention. Among the main measures, funding is provided for building safety measures, actions to strengthen seismic and volcanic monitoring networks, and a general simplification of administrative procedures, necessary to implement the provisions of the regulations and programs.

The set of measures adopted aims to ensure continuous, high-resolution monitoring and to prepare evacuation plans based on scientifically validated scenarios. It also seeks to ensure the operational continuity of essential services through the active and proactive involvement of the community in order to improve the population's resilience through information and training and thus reduce social and territorial vulnerability.
