The relationship between the topography of active mountain belts and surface deformation remains a central topic in tectonic geomorphology. In recent decades, morphometric analysis has been a key tool for investigating the interaction between relief, recent tectonic activity, and climate-controlled erosion. This review presents a synthesis of the analysis and interpretation of various morphometric indices applied in sectors of the Andes subjected to different tectonic and erosive regimes. Two case studies are presented, demonstrating how the quantitative analysis of landform morphology—drainage systems and topography—provides insights into the spatial and temporal evolution of active deformation and associated exogenous processes. Although the response of fluvial systems to factors such as climate, lithology, and uplift patterns may introduce ambiguities in the interpretation of topographic data, it is shown that the application of morphometric indices is an effective tool for characterizing deformation rates and patterns in active mountain chains. The selected cases correspond to the Guañacos Fold and Thrust Belt in the Neuquén Principal Cordillera of Argentina and Isla Grande de Chiloé in the North Patagonian Andes of Chile. In the Guañacos Fold and Thrust Belt, the indices enabled the identification of deformation patterns associated with recent tectonic activity and the analysis of the predominant erosive factors shaping the landscape. In the case of Isla Grande de Chiloé, the indices were applied to study the dynamics of glacial erosion and the effects of tectonics in an environment dominated by low-relief landscapes and extensive drainage networ ks. These examples highlight the potential of morphometry as a tool for understanding modern landforms and its application across various scales and geological contexts.
