Figure 9

Spatial distribution and related 𝑉 L O S field for the ENVISAT ascending (2003–2010) dataset over the central-eastern part of the Pitigliano town centre. Localized deformation is identified over some buildings, with downwards moving PS showing a progressive LOS displacement trend away from the satellite (a), while one downwards moving PS and some apparently stable PSs located close to the cliff edge share a common LOS displacement trend, especially since February 2007 (b).
