The Toba super eruption occurred between 69,000 and 77,000 years ago at Lake Toba (present day Indonesia), and it is recognized as one of Earth's largest known eruptions. The related catastrophe theory holds that this super volcanic event plunged the planet into a 6 to 10 year volcanic winter, which resulted in the world's human population being reduced to 10,000 or even a mere 1,000 breeding pairs, creating a bottleneck in human evolution. Some researchers argue that the Toba eruption produced not only a catastrophic volcanic winter but also an additional 1,000 year cooling episode.
