In this presentation, I will present you the results obtained in a recent publication entitled: «  Along-strike variations of strain partitioning within the Apennines determined from large-scale multi-temporal InSAR analysis, https://doi.org/10.1016/j.tecto.2023.230076 ». In this paper, we produced and analyzed a large set of GPS and InSAR measurements over the Apennines (Italy), where the origin of the long-wavelength topography and the driving mechanisms of the extension are debated. Our continuous mapping of the surface displacements across the range allows to understand how the different deformation scales (fault tectonic, landslides, surface processes, hydrological loading, mantle processes) are imbricated and how faults behave in relation to driving mechanisms at the boundaries of the system. Although, I hope this presentation can be relevant from the scientific point of view of various fields (seismology, geomorphology, geodynamic, remote sensing), here, I would like to particularly focus on numerical models and the development of inversion tools to derive the spatio-temporal evolution of seismic and aseismic slip on faults.
