Characterization of tropical rock glaciers in the Peruvian Andes using UAVs and satellite-derived surface velocities
Ecole polytechnique fédérale de Lausanne - EPFL
Lay summary
Rock glaciers are landforms consisting of ice and debris found in high mountain regions. They move downhill over time due to the frozen ground underneath them, known as permafrost. Rock glaciers are studied to gain a better understanding of climate change, water resources and natural hazards. Recently, Rock Glacier Velocity (RGV), the speed at which rock glaciers move, has become an important Environmental Climate Variable (ECV) for permafrost. However, there are very scarce data about the status of permafrost in tropical regions such as the Peruvian Andes. This project aims to address this issue by measuring how fast rock glaciers move in three regions of the Cordillera Volcánica in southern Peru. This will be achieved by taking high-resolution images of the rock glaciers using drones (UAVs) and satellite images. These images will help track movement over time, leading to a better understanding of mountain permafrost behaviour in the region. The project also plans to hold a workshop with local scientists to share knowledge about permafrost in the Andes. The project will produce a comprehensive dataset on the movement of rock glaciers in the Peruvian Andes. These data can be used to predict future changes in rock glacier dynamics and their impact on water resources in the region. Additionally, collaboration with local scientists will enhance regional expertise and contribute to more effective environmental management strategies.
