A two-day field trip on November 9-10, 2022, brought the IMPROVE researchers to meeting the Neapolitan volcanoes. Led by Sandro de Vita with the precious support by Domenico Sparice, the field trip developed on Vesuvius first, then on Campi Flegrei. The leading team by the INGV – Osservatorio Vesuviano illustrated the structure, composition, behavior, and volcanic products of these two nearby still different volcanoes – Vesuvius being a quiescent stratovolcano with a summit caldera, and Campi Flegrei a large caldera which has been in a state of unrest during last decades, and from where some of the largest eruptions ever in the Mediterranean and European regions originated. A lesson in the field at the Solfatara crater by Stefano Caliro illustrated the characteristics of the degassing in the area and the reconstructed underground degassing structure. Finally, the Director of the Osservatorio Vesuviano, Mauro Di Vito, kindly introduced the IMPROVE researchers to the modern 24/7 Operational Room where the data from four continuously monitored volcanoes are collected and analyzed.
