The thick, viscous lava flow in the center was erupted in 1961, when the rising lava dome spilled over the rim of the summit crater, eventually reaching the caldera floor by the end of 1962. The flow is seen here in 1978 from the caldera wall NW of the summit of Colima. El Volcancito, the lava dome forming the NE-flank knob on the left horizon, was formed during an eruption in 1869. The forested lava flow whose terminous forms the cliff at the lower right was probably erupted in 1872.
