413 Campi Flegrei CO2 Surge Forces 3 Million Naples Residents Into Danger

6 Feb 2026Campi Flegrei, a supervolcano near Naples, Italy, is emitting dangerous levels of carbon dioxide, posing a severe threat to the 3 million residents. The volcano’s emissions, primarily from hydrothermal decarbonation, have created an invisible network of potential death traps throughout the city. This crisis highlights the complex interplay between geological forces and human life in densely populated volcanic areas.Campi Flegrei, a supervolcano near Naples, is experiencing a crisis with escalating carbon dioxide emissions. The emissions, reaching 3,000 to 5,000 tons per day, are transported by Mediterranean sea breezes into Naples, posing a significant public safety concern. This crisis, characterised by ground uplift and increased seismic activity, has been ongoing for two decades, suggesting fundamental changes in the underlying magmatic system.
