Beneath the bustling city of Naples lies Campi Flegrei, a vast volcanic caldera that has remained largely quiet since its last eruption in 1538. Despite its apparent dormancy, ongoing geological activity beneath the surface reveals a restless and powerful force. This documentary examines the science behind this supervolcano, highlighting how shifts in underground pressure and ground deformation signal potential danger. With millions living in close proximity to this unstable region, the threat is not hypothetical—it is a real and present concern for local communities and beyond.
The film explores historical eruptions, modern monitoring efforts, and the implications of a future event on regional infrastructure and global climate. By combining expert interviews, satellite imagery, and on-the-ground footage, it provides a clear picture of the risks posed by this hidden geological giant. The presentation underscores the importance of preparedness and scientific vigilance in mitigating potential disaster. It serves as both an educational resource and a call to awareness about one of Europe’s most significant natural hazards.
