Quote:The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred around 74,000 years ago, during the Late Pleistocene,[2] at the site of present-day Lake Toba, in Sumatra, Indonesia.
. . . The Toba catastrophe theory holds that the eruption caused a severe global volcanic winter of six to ten years and contributed to a 1,000-year-long cooling episode, resulting in a genetic bottleneck in humans.
