Which super volcano released much dust into the atmosphere Lake Toba or the Yellowstone Caldera???
The most damaging super-volcano in human history was Toba, on Sumatra, Indonesia, 74,000 years ago. Because it was fairly close to the equator it injected gas quickly into both hemispheres. Ice core data shows that temperatures were dramatically reduced for five to six years afterwards, with freezing conditions right down to the tropics. Toba erupted with enough force to send more than 600 cubic miles of volcanic material into the atmosphere. Toba was the largest eruption of the past 500,000 years. Such violent, so-called caldera eruptions can drastically alter global climate, by spewing so much ash and sulfur compounds into the atmosphere as to block sunlight and lower temperatures worldwide.
