The largest eruption in South America in recorded history was in 1600, of which volcano?

Question

The highest and the lowest temperatures in South America since the beginning of the 20th century were both recorded in which country?

Answer 1

Huaynaputina, Peru
The eruption caused a volcanic winter globally. Temperatures in the Northern Hemisphere dropped, cold waves hit parts of Europe, Asia and the Americas, and the climate disruption is thought to have played a role in the onset of the Little Ice Age; floods, famines, and social upheavals resulted. Other names for the volcano include Chequepuquina, Chiquimote, Guayta, Omate and Quinistaquillas.
