Colima (left), with a plume of whispy steam drifting from its summit, and Nevado de Colima (right) form a pair of N-S-trending stratovolcanoes composing the Colima volcanic complex. The modern Colima cone was constructed during the past 2600 years within a large horseshoe-shaped caldera breached to the south that was formed by edifice collapse. The modern edifice has overtopped the eastern caldera rim (roughly corresponding to the vegetation line), and unvegetated lava flows erupted during 1975-76 spill down its outer flanks.
