2.2. Building description The building, presumably constructed between the 1960s and 1970s, falls in the upper part of the landslide, in the detachment zone. The building underwent significant foundation settlements, being in a rather vulnerable area and subject to the slow and intermittent movements of the landslide, as seen in Section 2.1. It is composed by reinforced concrete orthogonal frames creating a rectangular plan and has three levels, for a total height of 8,1 m (Fig. 2).

The roof of the building has two pitches of approximately 18° and 15°. From the in-situ survey, masonry infill was observed on the ground floor, characterized by a wall face of tuff bricks for three facades and a horizontal infill of hollow clay bricks for the fourth one. Further information on the building can be found in Miano et al. (2021). 3. Methodology The methodology applied in this work is the same one illustrated in Miano et al. (2021). The velocity displacement components affecting the case study building are identified by means of a PS-like approach Technique (Ferretti et al., 2001) applied to satellite SAR images: the Coherent Pixels Technique (CPT), which allows the identification and calculation of displacement components, through DInSAR. The building is modeled as described in Section 3.1. The same 3D model used in Miano et al. (2021) is adopted. The components of the displacement along the horizontal
