Details for: Purace
Snow-capped Puracé volcano has a 500-m-wide summit crater and was constructed over a dacitic shield volcano. It is one of the most active volcanoes in Colombia, with a 500-m-wide summit crater. Frequent explosive eruptions in the 19th and 20th centuries have modified the morphology of the summit crater. The largest eruptions occurred in 1849, 1869, and 1885.
