In the Campi Flegrei, the increase in carbon dioxide (CO2) emissions of magmatic origin is raising concerns about public safety.
Article Key Points
In the area, already known for its geothermal activity, four geochemical monitoring stations are active: three located in the Solfatara and one in Pisciarelli. These stations are essential to control degassing and prevent risks for the population.
In addition to continuous monitoring, monthly campaigns are conducted to measure the gases emitted by the fumaroles, with the aim of ensuring maximum safety.
Checks in basements and cellars
The authorities, after the meeting yesterday afternoon chaired by the Prefect of Naples, Michele Di Bari, have started inspections and checks in the most critical areas, between Solfatara, Pisciarelli and Agnano.
The interventions are concentrated in the basements and cellars of public and private buildings, where carbon dioxide could accumulate. A small area of Bacoli, Scalandrone, is also under observation. Here, in an area called "Mofeta", there are fumaroles and sulphurous fumes known since 1966, but systematically studied only since 1980.
Risk of asphyxiation: the Civil Protection's alarm
The flow of CO2 from the soil in the Solfatara area increased from 4.000 to 5.000 tons per day in 2023, values comparable to those of active volcanoes with persistent degassing.
The Civil Protection, through the information campaign "I don't risk", reiterated the importance of avoiding depressed areas and areas close to volcanic gas emissions, where the risk of asphyxiation is particularly high. Carbon dioxide, in fact, can compromise lung capacity: when its concentration increases, the blood struggles to get rid of it, reducing the space for oxygen. Without oxygen, life is not possible.
Sensitive areas under the lens
Authorities are working to map the risk zones in detail, identifying specific streets and house numbers. The goal is to identify structures with a high social impact, such as schools, retirement homes or commercial activities, that could be exposed to the danger. Cellars and basements, often used as storage or work spaces, represent a critical point, especially if frequented by employees or business owners.
Situation under control, but caution is needed
Although extreme cases are rare, authorities stress the importance of not underestimating the phenomenon. Monitoring and prevention actions are considered essential to safeguard public safety. In the meantime, monthly bulletins continue to keep attention high on a volcanic area among the most monitored in the world, but also among the most unpredictable. Collaboration between institutions and citizens remains essential to face a challenge that combines science, safety and respect for the territory.

It is important that the authorities carry out more frequent checks because safety is fundamental. The increase in CO2 is a serious problem and should not be underestimated. The population must be informed and prepared for these risks.
