“…In Italy, landslides are one of the most dangerous and widespread geohazards, as they often cause loss of human lives and severe economic damage to the social fabric [1][2][3]. Landslides, defined by Cruden and Varnes [4] as the "movement of a mass of rock, debris or earth down a slope", are a constant threat to towns and villages in Southern Italy [5,6], where settlements have often expanded over areas threatened by dormant landslides [7]. The village of San Marco dei Cavoti (Benevento, Campania) is one of such southern Italy settlements affected by slope deformations causing damage to buildings and the road network.…”

Landslides pose significant risks to towns and villages in Southern Italy, including the San Marco dei Cavoti hamlet (Benevento, Campania), where settlements have expanded into areas threatened by landslides, leading to property damage, disruption to the social fabric and loss of life. This study aims to investigate the surface deformations in the area using Differential Interferometry SAR (DInSAR) analysis on COSMO-SkyMed radar imagery and to assess the potential implications for landslide activity. The DInSAR analysis methodology allowed us to obtain high-precision results presented as time series diagrams and maps of cumulative displacement for the study area. Furthermore, the displacement rates derived from the DInSAR analysis were decomposed into vertical and horizontal components to provide better insights into the slope processes and their potential impacts on the San Marco dei Cavoti hamlet. Our significant findings revealed active slope movements and the uphill enlargement of previously inventoried landslides threatening the San Marco dei Cavoti hamlet. These insights contribute to a better understanding of the landslide dynamics in the region and highlight the areas that may require further investigation or intervention measures. In conclusion, this study demonstrates the effectiveness of DInSAR analysis in providing valuable insights into landslide dynamics and informing potential mitigation measures for at-risk communities. This technique could be applied to other landslide-prone regions to support informed decision-making and enhance the safety and resilience of affected communities.
