This was followed in the second stage by trachytic, green or grey ignimbrites, trachytic and phonolitic lava domes and additional basaltic lava flows. The second stage ignimbrites can be found within the northern caldera and on the southern flank of the volcano. The third stage was dominantly phonolitic, with 382:, which together form a 15-by-11-kilometre (9.3 mi Ă— 6.8 mi) wide elliptical caldera that extends from northwest to southeast. The northern caldera formed first, then the southern caldera which is about 50 metres (160 ft) deeper below the northern one. 400–300-metre (1,310–980 ft) high 635:
beds have been found 125 metres (410 ft) above the floor of Era Kohor and in depressions without outlet elsewhere in the caldera, they reach thicknesses of 4–5 metres (13–16 ft). Farther down on the mountain, gullies start appearing at 2,800 metres (9,200 ft) elevation and become deep

Quaternary volcanism gave rise to the cones on the slopes of Emi Koussi, and the three maars are the most recent vents in the combined caldera, while long lava flows have been interpreted to be the youngest volcanism at Emi Koussi. The most recent volcanic vents show little erosion. Early in the
