Morphological Analysis of Nevado de Toluca Volcano: Insights into Structure and Evolution

Explore the morphological analysis of Nevado de Toluca volcano in Mexico, revealing new insights into its structure and evolution as an andesitic to dacitic stratovolcano. This study utilizes various data sets and methodologies to characterize the volcanic and tectonic structures of this recently evolved volcanic region, with minimal exogenous processes. Detailed analysis of linear and areal data helps identify structural and volcano-structural features, geologic framework, and morphological homogeneous zones related to volcanic edifices.
