The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago, during the Late Pleistocene, [2] at the site of present-day Lake Toba, in Sumatra, Indonesia.
About 74,000 years ago, Sumatra’s Mount Toba experienced a super-eruption, one of the largest in Earth’s history, potentially kicking off a massive disruption in the world’s climate.
The Toba eruption (the Toba event) occurred at what is now Lake Toba about 73,700±300 years ago. [15] It was the last in a series of at least four caldera-forming eruptions at this location, with the earlier known caldera having formed around 1.2 million years ago. [16]
A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles). [2] Location of Yellowstone hotspot over time.
