NorAm/Toluca/TolucaMap.jpg

Dog not for scale

Introduction Morphological analysis as tool to characterize volcanic and tectonic structures Recently evolved volcanic region Minimal exogenous processes

Morphology and Spatial Distribution Linear data Areal data

Linear Data Identifies structural and volcano-structural features

Areal Data Morphological homogeneous zones Related to volcanic edifices

Geologic Framework

Methodology DEM derived shaded images –Slope value distribution –Aspect distribution Aerial photographs –Domain characterization –Edifice identification

Data Summary

Feature Identification Rectilinear Curvilinear

Nevado de Toluca East opening Horseshoe 4 Merapi type dome collapses 4 Plinian eruptions Glacier activity
