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.
