Short summary
Thanks to the availability of a portable absolute gravimeter allowing field operations, in 2015 a dense absolute gravity network was established in Campi Flegrei and till 2019 five surveys were carried out. Results suggest that the present activity may be due to the alternating recharge/discharge of fluids in the surface hydrothermal system. They also confirms the feasibility of this methodology for volcano monitoring, and encourage replacing the relative networks with absolute ones.
