Description
Summary:[EN] Landslides represent a significant hazard in many mountainous regions, including the inter-Andean valleys of Peru. In this study, we evaluate the dynamics of the Cuenca landslide located in Huancavelica, central Peru, using photogrammetry and GNSS measurements. Interannual measurements were conducted at eight sites between 2016 and 2023 for GNSS, and two photogrammetric survey campaigns in 2023 to compare surface changes over time. The results show displacements ranging from 3.7 to 11.7 cm using the point cloud technique and from 2.7 to 15 cm through orthomosaic analysis, with both methods yielding consistent results. Displacements at points where GNSS measurements were taken are similar in magnitude but differ partially in direction. The study concludes that UAV techniques are applicable for analyzing landslide dynamics.
