GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 1.1 GNGTS 2023 It is also shown that 83% of the deformation in terms of length of the surface faulting is located at the hanging wall of the main rupture, while at the footwall it is located the remaining 17%. There is a significant correlation between vertical separation, rupture zone width, the position of the rupture (footwall or hanging wall), and fault geometry. From these correlations, has been highlighted the control of obliquity and kinematic partitioning in the surface expression of the earthquake propagation. We interpret the coseismic and long-term behavior, showing that the two activated segments had similar cumulated behaviours in distributing the deformation over time, even with different geometries (Bello et al., 2022). We calculate ratios applying probability density functions, that are consistent with most of the literature but not spatially uniform. These results deserve to be considered in studies on active faulting hazard and suggest caution in establishing rules for land use planning close to active faults capable of rupturing the surface.
