The Toba eruption (sometimes called the Toba supereruption or the Youngest Toba eruption) was a supervolcano eruption that occurred about 74,000 years ago during the Late Pleistocene[1] at the site of present-day Lake Toba in Sumatra, Indonesia. It is one of the largest known explosive eruptions in the Earth's history. The Toba catastrophe theory is that this event 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.[2][3] However, some physical evidence disputes the association with the millennium-long cold event and genetic bottleneck, and some consider the theory disproven.[4][5][6][7][8]
