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.
Toba supereruption Pleistocene human population bottleneck Toba catastrophe theory Bcndz5 09:28, 5 April 2023 (UTC) Maybe, considering that recent studies on the Toba supereruption have dramatically increased its volume estimates, and has been mentioned to be among the largest ignimbrites ever discovered.
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]
One focus of investigation is the huge “supereruption” (a word coined by Rampino and Self) of Mount Toba (now Lake Toba) in Sumatra ~74,000 years ago. [39] This event may have created a severe “volcanic winter” (another term coined by Rampino) leading to a human population crash predicted from studies of the human genome. [40]
Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...

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).
