Indonesia’s Lake Toba Supervolcano Threatens Global Volcanic Winter: Eruption Caused Mass Extinction 75, 000 Years Ago

Indonesia’s Toba supervolcano – the site of the world’s largest volcanic lake in Sumatra –came alive late last month, producing hot steam and foul smelling gas. The recent activity has raised fears of a major eruption after 75,000 years.

Toba Volcano, according to reports in the Indonesian media, is presently producing large emissions of steam and the ground in the area around the volcano is giving off foul odors of gas. Locals have also reported feeling the ground hot under their feet.

The latest activity is reportedly spreading panic among residents of the Toba area.

According to Dutchsinse, Toba supervolcano has a larger eruptive power than the Yellowstone supervolcano in Wyoming, United States.

Researchers say that Toba was responsible for two major global environment altering events in the last 2 million years, erupting on four different occasions in the Quaternary Period: 840,000 years ago, 700,000 years ago and finally about 75,000 years ago.

Scientific researchers believe that the last massive eruption of the volcano, 75,000 years ago, caused a dramatic change in global climate that led to a global volcanic winter. The volcanic winter caused a large part of global human population to die off, leaving only about 15,000 humans, thus causing a global population bottleneck that narrowed the genetic variability of the human race and restricted the direction of subsequent evolutionary history of the human species.

The scientific hypothesis that a massive eruption of the Toba volcano 75,000 years ago caused a global human population bottleneck and mass extinction of species is known as the Toba catastrophe theory/hypothesis.
