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
