About 70,000 years ago, the Toba Supervolcano erupted in what is now Indonesia. After the eruption, the ground collapsed and left behind a depression called a caldera, which is not filled by Lake Toba and volcanic domes that have emerged in the time since, as seen in this set of images taken Jan. 28, 2006, by NASA's Terra satellite and then stitched together.
Humans didn't enter the Indian subcontinent until after the massive eruption of Mount Toba in Sumatra nearly 75,000 years ago, new research suggests — overturning a previous idea that humans arrived much earlier.
The research, published today (June 10) in the journal Proceedings of the National Academy of Sciences, used a combination of archaeological and genetic data to suggest a new earliest possible date for the exodus from Africa to Asia.
The new data suggest humans left Africa to arrive in South Asia around 55,000 to 60,000 years ago — long after the Mount Toba supereruption 74,000 years ago. That contradicts some archaeologists' claims that modern humans have been living in the region for twice that long.
