Slope failure has occurred repetitively from both Volcán Colima (left) and Nevado de Colima (right) and has produced a thick apron of debris-avalanche deposits on three sides of the complex. This steep-sided, 120-m-deep canyon wall at La Platanera, SE of Colima, exposes deposits inferred to represent at least seven major debris avalanches. The sloping vegetation line on Colima volcano marks the largely buried rim of a horseshoe-shaped caldera that has been the source of one or more recent avalanches.
