Photo Gallery

Colachi (left) is an andesitic-dacitic stratovolcano whose most recent activity produced pristine silicic lava flows of probable Holocene age. The largest of these covers a 7 sq km area on the saddle between Colachi and the neighboring volcano of Acamarachi (center horizon). This aerial view from the west also shows the conical peak of Aguas Calientes (far right), a twin volcano of Lascar volcano, whose slopes appear at the lower right. The Talabre valley in the center foreground is partially filled by an andesitic lava flow from Lascar.

Two youthful large silicic lava flows flank the summit of Colachi volcano (upper left). The larger flow (bottom) covers a 7 sq km area at the SE base of the volcano. The smaller flow on the NW flank is visible at the upper left. A smaller lava flow with pronounced lateral levees was erupted from a vent on the eastern flank.
