How often does Toba erupt?
“Toba is at least 1.3 million years old, its supereruption took place about 74,000 years ago, and it had at least six definitive eruptions after that — and probably several more,” Mucek said. “The last eruption we have detected occurred about 56,000 years ago, but there are other eruptions that remain to be studied.”
What would happen if Lake Toba erupted?
If the Toba eruption did indeed send vast quantities of sulphur dioxide around the world, scientists have predicted it may have sparked a volcanic winter, which blackened the skies and lasted several years.

Will Toba erupt soon?
The researchers say that an extra four cubic kilometres of magma builds up in Toba every thousand years. This means that next equivalent super-eruption would occur in 600,000 years – though smaller ones could happen in the meantime.
How many eruptions has Toba had?
four
Photo by Tom Casadevall, 1987 (U.S. Geological Survey) The 35 x 100 km Toba caldera was formed during four powerful explosive eruptions beginning 1.2 million years ago. The latest of these, about 74,000 years ago, was one of the world’s largest known Quaternary eruptions, producing the Young Toba Tuff (YTT).
Will Lake Toba erupt?
Will a supervolcano end the world?
Ultimately, global temperatures would drop, plants would die, and agriculture would fail. In fact, the UN estimates that the entire world would run out of food in just over two months. Now, Yellowstone has a history of eruptions like this. It’s erupted three times in the past 2.1 million years.
When did humanity almost go extinct?
Around 70,000 years ago, humanity’s global population dropped down to only a few thousand individuals, and it had major effects on our species. One theory claims that a massive supervolcano in Indonesia erupted, blackening the sky with ash, plunging earth into an ice age, and killing off all but the hardiest humans.
