Toba catastrophe theory

The Toba supereruption was a supervolcanic eruption that occurred about 75,000 years ago at the site of present-day Lake Toba (Sumatra, Indonesia). It is one of the Earth's largest known eruptions. The Toba catastrophe theory holds that this event caused a global volcanic winter of 6–10 years and possibly a 1,000-year-long cooling episode. The Toba event is the most closely studied supereruption.
