Short summary
We revised the conceptual model of the Solfatara magmatic–hydrothermal system and used new geothermometers and geobarometers, specifically calibrated for the Solfatara fluids, to monitor temperature, T, and total fluid pressure, P, in three distinct reservoirs at different depths, over ~40 years. The T and P changes in the intermediate reservoir (at 2.7–4 km depth) are of utmost interest because its pressurization–depressurization acts as the “engine” of bradyseism currently affecting the area.
