Ulleungdo erupted around 8,750 BCE with a Volcanic Explosivity Index (VEI) of 6, a colossal eruption that threw tens of cubic kilometres of ash and rock into the air. 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 8,750 BCE.
