Investigating Gravitational Slope Deformations with COSMO-SkyMed-Based Differential Interferometry: A Case Study of San Marco dei Cavoti

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