The 250-m-wide Chongou-Chagnoumeni pit crater (center) cuts the northern part of the compound summit caldera of Karthala volcano. The steaming 30-m-deep pit crater was formed during an eruption in 1918 that also greatly enlarged the Chongou-Chahale pit crater to the south. Unvegetated lava flows from the 1972 eruption cover the caldera floor behind the pit crater.
