| description | Landslides are a major global threat, endangering lives, infrastructure, and economies. This paper introduces the <i>Geohazard</i> plugin, an open-source tool for QGIS, designed to support medium–small-scale landslide analysis and management. The plugin integrates several algorithms, including the <i>Groundmotion–C index</i> for evaluating SAR data reliability, <i>Landslide–Shalstab</i> for assessing shallow landslide susceptibility, and <i>Rockfall–Droka</i> for estimating rockfall invasion areas and the rockfall relative (spatial) hazard. An application example is provided for each module to facilitate validation and discussion. A case study from the Western Italian Alps highlights the practical application of the <i>Rockfall–Droka</i> modules, showcasing their potential to identify critical zones by integrating the results on affected areas, process intensity, and preferential paths. Emphasis is given to the calibration of model parameters, a critical aspect of the analysis, achieved through a back-analysis of a rockfall event that occurred in June 2024. The <i>Geohazard</i> plugin streamlines geohazard assessments, providing land managers with actionable insights for decision-making and risk mitigation strategies. This user-friendly GIS tool contributes to enhancing resilience in landslide-prone regions. |
