Was monitoring at Campi Flegre has been strengthened i, with the installation of a new observatory in the marine area of the Gulf of Pozzuoli in which the caldera of the super-volcano extends: the monitoring network called Jellyfish which will now be supported by a new infrastructure of the Vesuvian Observatory of the National Institute of Geophysics and Volcanology with the aim of study gas emissions in the underground sector . The installation, also created thanks to the contribution of the Civil Protection Department, was made possible thanks to the INGV diving group, in coordination with the Campi Flegrei Archaeological Park.
The affected area was identified in a particular sector of the Gulf of Pozzuoli known as ‘ Secca delle Fumose ‘, already the subject of studies and monitoring and where the installation of other marine scientific instruments is also planned. It is, in fact, a focal point of Phlegraean thermalism, where already in ancient times the emergence of hot waters and vapors was evident, so much so that it pushed the ancient Romans to build, unique in its kind, an artificial island that allowed take advantage of the healthiness of the phenomenon.
The new marine observatory will make it possible to constantly monitor the temperature of hydrothermal emissions on the seabed, the concentration of carbon dioxide of volcanic origin dissolved in sea water and the sea current: all useful parameters for estimating the energy associated with the emission gas subsea and for monitoring any variations. This new instrumentation, therefore, strengthens the existing infrastructure at the Campi Flegrei in the submerged sector of the caldera, which presents objective logistical difficulties.
