Petrology and thermal modelling to delineate scenarios for the evolution of the 75 years long unrest at Campi Flegrei

Campi Flegrei are one of the most dangerous active volcanoes on Earth with approximately 2 million people leaving within its caldera. Since the 1950’s the centre of the caldera has uplifted more than 5 m, with 4 main unrest episodes, the last of which is currently ongoing. I will first present a summary of the eruptive history of Campi Flegrei, and the most recent studies, before presenting the results we obtained to constrain the volume of eruptible magma currently present at 4-5 km depth and to identify the trigger mechanisms of past eruptions of different intensity. Our results serve to delineate plausible future scenarios for the evolution of the ongoing unrest.
