106 GNGTS 2022 Sessione 1.2 Short-lived water temperature decreases during the strongest earthquakes of 2018-2019 excluded coseismal impulsive input of hot or cold water into the aquifer, but rather suggested temporary lowering of the water table level or accumulation of cold gas at the top portion of the monitored water well, replacing thermal water and hence decreasing the measured temperature. We think that the data collected during the present investigation represent a base point for a predictive model of seismic and slow tectonic events based on high-frequency monitoring of geothermal fluid emissions.  References Bottari C., Giammanco S., Cavallaro D., Sortino F., Scudero S., Amari S., Bonfanti P., Daolio M. and Groppelli G.; 2020: How to reveal unknown hidden faults and historical earthquake damage applying multidisciplinary methods in archaeological sites: The case of mid- third century CE Mt.
