Revisiting Hazard Assessment for the Deep-Seated Gravitational Slope of Paterno (Central Italy)

The study presented here proposes an approach, based on the combination of InSAR techniques and geological field observations, to assess and quantify the hazard of the Deep-Seated Gravitational Slope of Paterno (Rieti, Central Italy). The deformation process that affected the Paterno slope has already been identified and featured by high landslide hazard rank in the PAI catalogue, which designs territorial planning documents. Until nowadays, the Paterno slope movement has never been investigated in depth. The new data collected contribute to revisiting of landslide hazard level in the study area, where old settlements and other infrastructures are located. The lack of evidence of activity of this deformation process suggests a lower hazard rank concerning that assigned in the PAI and, therefore, needs reviewing.
