Fear in the Campi Flegrei, devices under the underwater sea to predict earthquakes
INGV divers have installed a new observatory in the Secca delle Fumose to collect useful data to prevent possible ground movements linked to bradyseism
NAPLES – The Campi Flegrei caldera also extends into the marine area in the Gulf of Pozzuoli, where the ‘Medusa’ multi-parametric geophysical monitoring network is already present. In order to strengthen the multiparametric geochemical research and monitoring infrastructure of the Vesuvian Observatory of the National Institute of Geophysics and Volcanology, a new multiparametric observatory has recently been installed in the submerged sector of the Phlegraean caldera for the study of the degassing process. underwater hydrothermal.
HOW THE UNDERWATER OBSERVATORY WILL WORK
“This installation, also created thanks to the contribution of the Civil Protection department, is part – so a note from the INGV – among the numerous activities for the implementation and strengthening of the networks and general investigations on this sector of the caldera”.
The installation was made possible thanks to theIngv diving group, coordinated by the Fluid Geochemistry functional unit of the Ingv-Vesuvian Observatory, in coordination with the archaeological park of Campi Flegrei and the other authorities in charge.
The area concerned has been identified in a particular sector of the Gulf of Pozzuoli known asSecca delle Fumose, already the subject of studies and monitoring, where the installation is planned of other marine scientific instruments.
The new marine observatory allows continuous monitoring of the temperature of the hydrothermal emissions in the bottom, the concentration of carbon dioxide of volcanic origin dissolved in the sea water and the marine current: all useful parameters for estimating the energy associated with the underwater degassing process and monitoring any variations.
“This new instrumentation – communicates the Ingv – strengthens the multi-parametric network infrastructure already existing in the Campi Flegrei caldera in the submerged sector of the caldera, which presents objective logistical difficulties”.
