The greatest threat to human existence from any source was a volcanic eruption that occurred about 73,500 years ago, caused by the Toba volcano in Sumatra, Indonesia. The eruption was a super-eruption, which is defined as an eruption with an ejecta volume greater than 1,000 cubic kilometers or more than 10 times the volume of Mount St. Helens' 1980 eruption. The Toba eruption, which was one of the largest volcanic events in human history, had serious consequences for life on Earth, including triggering a volcanic winter, which caused a global cooling of the planet's surface, lowering average global temperatures by 3 to 5 degrees Celsius. This, in turn, led to a significant reduction in the Earth's biodiversity, including the near-extinction of the human species.
