The NE-most of two block lava flows emitted during the 1975-76 eruption descended the flank of the summit cone until it encountered El Volcancito (lower right), the NE-flank lava dome emplaced in 1869. The flow then bifurcated into two lobes, one of which was deflected to the north of Volcancito, and the other to the south. This flow (center) eventually reached down to about 2500 m elevation on the eastern flank. The Colima graben floor at the upper left is blanketed by debris-avalanche deposits formed by collapse of the volcano.
