It is a caldera formed from the collapsed volcano after it emptied it´s magma chamber during the eruptions dating back to 500 B.C. or 2500 years ago. This type of formation is typical of very strong eruptions that weaken the internal structure of a volcano. The caldera has three lava domes, Pondoña, El Chivo, and Pan de Azucar, which formed in the years following the eruption, and after the volcano collapsed. The highest elevation of this volcano is the Sincholagua hill on the north eastern side of the caldera at an elevation of 3356 meters.
