Cerro Azul volcano
It is an active stratovolcano in the Maule Region of central Chile, immediately south of Descabezado Grande.
Part of the South Volcanic Zone of the Andes, its height is 12,428 ft above sea level, and is capped by a summit crater that is 1,600 ft wide and opens to the north.
Beneath the summit, the volcano features numerous scoria cones and flank vents.
Cerro Azul is responsible for several of South America's largest recorded eruptions, in 1846 and 1932. In 1846, an effusive eruption formed the vent at the site of present-day Quizapu crater on the northern flank of Cerro Azul and sent lava flowing down the sides of the volcano, creating a lava field 3–3.5 square miles in area.
In 1932, one of the largest explosive eruptions of the 20th century occurred at Quizapu Crater and sent 9.5 cubic kilometres (2.3 cu mi) of ash into the atmosphere.
The volcano's most recent eruption was in 1967.
