The Central Andes had the largest volcanic eruption of the last 5000 years
Cerro Blanco Volcanic Complex, located in the south of the Altiplano-Puna plateau, erupted around 4,200 years ago. But it was not an ordinary event. It was the largest eruption of the last 5,000 years in the Central Volcanic Zone of the Andes according to a new study published in the journal Estudios Geológicos. The estimated volume of ejected ash places this eruption amongst the largest eruptions of the Holocene Era (the last 11,700 years).
