Campi Flegrei, in the Gulf of Pozzuoli the system to monitor the underwater volcanic caldera has been strengthened

To obtain more and more precise data on the volcanic caldera at Campi Flegrei, on bradyseism and earthquakesthe INGV Vesuvian Observatory the research and monitoring system was strengthened underwater caldera of the supervolcano. Right in the sector of the caldera which is located under water, in the Gulf of Pozzuolia new monitoring system has been installed, equipped with highly sensitive sensors, which allows an even more accurate study of the underwater hydrothermal degassing process.

The new monitoring system has been installed in a particular sector of the Gulf of Pozzuoli called “Secca delle Fumose”, already the subject of studies and research and where, in the coming weeks, new instrumentation will be installed. The installation of the new monitoring system was carried out thanks to the INGV diving group, coordinated by the Fluid Geochemistry Functional Unit of the Vesuvian Observatory.

With the new observation infrastructure it will be possible to constantly monitor the temperature of hydrothermal emissions, the concentration of carbon dioxide of volcanic origin dissolved in the sea and the marine current. These are all useful parameters for estimating the energy associated with submarine degassing and monitoring any variations.
