Eruption of Blanco, Cerro

c. 2,300 BCE

Blanco, Cerro erupted around 2,300 BCE with a Volcanic Explosivity Index (VEI) of 7, one of the largest eruptions of the last 10,000 years. Eruptions of this size inject sulphur into the stratosphere and can cool the global climate for a year or more. The VEI is a logarithmic scale: each step means roughly ten times more erupted material. It took place around 2,300 BCE.
