Eruptive History
Cerro Azul has a history of eruptions dating back to at least 1846. The known events include effusive eruptions (lava flows), which created the Quizapu vent, explosive eruptions, and phreatic eruptions. Pyroclastic flows have also been observed as a result of some of these explosive eruptions. The earliest recorded eruption began on November 26, 1846, while the volcano's last eruption began on August 9, 1967. The volcano has produced two of the largest eruptions in South America in recorded history, in 1846 and 1932. Both released 4–5 cubic kilometers (1.0–1.2 cu mi) of the dacitic magma. (The more recently described eruption of Huaynaputina in 1600 appears to have been larger.)

Famous quotes containing the word history:
“What you don’t understand is that it is possible to be an atheist, it is possible not to know if God exists or why He should, and yet to believe that man does not live in a state of nature but in history, and that history as we know it now began with Christ, it was founded by Him on the Gospels.”
—Boris Pasternak (1890–1960)
