Parinacota contains a pristine, 300-m-wide summit crater and young lava flows on the western flanks. There are no historical eruptions, but the volcano has had explosive and effusive eruptions from both the summit crater and the Ajata group of flank vents in the past few 1000 years and is considered an active volcano. Background:A large sector collapse occurred at Parinacota about 8000 years ago. The 6 km3 avalanche travelled 22 km to the west and created a dam, where Chungará Lake (4520 m) was formed. The lake sediments provide important information about environmental and climate changes in the tropical Andes.Laguna de Cotacotani (4495 m) is another lake on the SW flank of the volcano. |
