Description:
We present a morphological analysis of Nevado de Toluca volcano located 80 km WSW of Mexico City based on digital
elevation model study, where slope and aspect maps have been generated and analysed. Aerial photograph and satellite image
observations improve the morphological analysis. The synoptic view which is offered by this analysis allowed for recognition
and localization of the main volcanic and tectonic features of the area. On the basis of digital elevation model value distribution
and surface textures, five morphological domains were defined. The most interesting domain, south of the crater, reflects the
occurrence of an ancient complex volcano distinct from the adjacent areas. Interaction between the volcanic and volcano–
tectonic evolution and the basement produced the other domains. Single volcanic edifices, like lava domes and scoria cones, and
eruptive fractures were recognized. Finally, flank collapse scarps opened to the east and to the north were identified and four
relevant morphostructural lineaments and their possible role in the Nevado de Toluca geological and structural evolution are
discussed.
