Campi Flegrei, a laser sensor detects high concentrations of hydrogen sulphide: the study
At the fumarole in the Pisciarelli areain the Campi Flegrei caldera, a special laser sensor detected high concentrations of hydrogen sulfide, a highly toxic gas for man. The concentrations are 12 times higher than the safety threshold and were detected during measurement campaigns carried out between May 2025 and February 2026 within a few meters of the fumarole. Fortunately, measurements ...
