Sumatra was the site of a ancient "super-eruption".

However, the volcanism there is of a somewhat different variety than at Yellowstone, a more famous location for super-eruptions.

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 in 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 six to ten years and possibly a 1,000-year-long cooling episode.

In 1993, science journalist Ann Gibbons posited that a population bottleneck occurred in human evolution about 70,000 years ago, and she suggested that this was caused by the eruption.

Geologist Michael R. Rampino of New York University and volcanologist Stephen Self of the University of Hawaii at Manoa support her suggestion.

In 1998, the bottleneck theory was further developed by anthropologist Stanley H. Ambrose of the University of Illinois at Urbana–Champaign.

Both the link and global winter theories are highly controversial.[1]

The Toba event is the most closely studied supereruption.[2][3] ...”
