Atacazo volcano is part of the Atacazo–Ninahuilca Volcanic Complex in the Western Cordillera of Ecuador and located 10 km southwest of the capital of Ecuarod, Quito.
The andesitic Atacazo stratovolcano is a successor of the older La Carcacha stratovolcano. It was built above a 6 km wide and 900 m deep caldera. The caldera is breached to the SW and contains 3 Holocene dacitic domes. The youngest lava dome, Ninahuilca, erupted about 2300 years ago. 2 andesitic lava domes are also found on the SE flank.
Several large Plinian eruptions have occurred at the volcano during the past 10,000 years and accompanied the growth of the lava domes. The formation of the most recent dome, Ninahuilca Chico, was accompanied by explosive eruptos that produced pyroclastic flows that flowed up to 35 km distance through valleys towards the west.
