Abstract
The Solfatara-Pisciarelli area represents the most active zone within the Campi Flegrei caldera (CFc) in terms of hydrothermal manifestations and local seismicity. Periodic injections of hot CO2-rich fluids at the base of a relatively shallow hydrothermal system has already been correlated to ground uplift in a wide range of numerical modelling of the CFc unrests, that highlight a strong correlation between chemical composition of the Solfatara and Pisciarelli fumaroles, seismicity and ground movements. In particular, a new simulation has been realised via the coupling of TOUGH2©and Comsol Multiphysics©. Recent uplift episodes in the in the centre of Pozzuoli Bay have been reconstructed imposing fluid flows in the system as experimentally recorded. Numerical studies, geochemical data and Magnetotelluric (MT) survey have been integrated, to guess the main features of the shallower part of the hydrothermal system of the Solfatara-Pisciarelli area.
