Camastra Dam Failure: Earthquake Collapse versus Total Reservoir Loss Risk Aversion

Communities worldwide are increasingly vulnerable to various natural and anthropogenic hazards, with critical infrastructure projects like dams playing a pivotal role in risk mitigation. The Camastra Dam in Southern Italy serves as a case study of how stringent seismic regulations, imposed without sufficient consideration of broader environmental and socioeconomic factors, exacerbated risk exposure. Operational constraints on the dam, implemented in response to seismic safety concerns, have reduced its storage capacity, leading to severe water shortages during an ongoing drought. This situation highlights the necessity for adaptive governance frameworks that address both the immediate and long-term consequences of natural hazards. The interplay between seismic vulnerability, hydraulic performance, and climate resilience underscores the unintended consequences of prioritizing one risk over others. Anthropogenic climate change has intensified risks such as floods, droughts, and rainfall clustering, further complicating infrastructure resilience. Drawing on global examples of disaster risk management, the Camastra Dam case advocates for more integrated approaches to disaster prevention, mitigation, and recovery. It calls for the use of multirisk frameworks that combine probabilistic seismic hazard assessments, hydrological modeling, and climate projections to safeguard communities against cascading risks and enhance infrastructure preparedness in the face of growing environmental uncertainty.
