Session 1.1 GNGTS 2023 Fig. 2 – 3D numerical model with the isopiezometric distribution a) before Vettore fault rupture and b) after fault rupture. Future developments We are going to create a geomechanical failure model to assess the crustal stress-strain field variation related to the seismogenic fault dislocation. The model will be calibrated using a fem numerical inversion of interferometric SAR data available for the 30 October earthquake. The calculated volumetric strain changes will be helpful to calibrate the hydraulic parameters in the hydrological model of groundwater filtration.
