Session 1.3 GNGTS 2023 Fig. 1: Comparison between the temporal evolution of the geodetic signal IC2 (in orange) and the Boiano Spring flow (in blue). Fig. 2 : The Matese area and the main Quaternary Fault System (black lines) BBF - Boiano Fault; PMF - Piedimonte Matese Fault; SGF - San Gregorio Fault; MLF - Matese Lake Fault; AIF - Aquae Iuliae Fault (as reported in Esposito et al., 2020); the maximum displacements from ICA due to hydrological processes (green arrows); the principal strain axes (red arrows) show that the largest component of deformation induced by water circulation is extensional and directed normal to the faults; red and white balloon represent the extensional style source of the largest earthquake occurred in the analyzed time span. Acknowledgements This work has been done within the framework of the Earthquake Department Strategic Project FURTHER (Project coordinator F. Di Luccio, WP4 Coordinator A. Esposito). We wish to thank: Regioni Campania and Molise for the rain gauge data, Luca Pizzino for the Boiano spring data; the Bernese team of INGV and the data providers of the 7 GNSS stations. Seismic data are from the INGV earthquake data bank, selected by F. Di Luccio.
