The Toba Supereruption

The Toba Supereruption occurred around 74,000 years ago and was one of the most powerful volcanic eruptions in Earth’s history. The eruption ejected an estimated 2,800 cubic kilometers of ash and debris, which caused a global volcanic winter that lasted for several years and is believed to have caused a genetic bottleneck in human populations. The eruption also created a massive caldera, which later filled with water to form Lake Toba.

The Impact of the Toba Supereruption

The Toba Supereruption significantly impacted the global climate and human evolution. The eruption caused a global volcanic winter, which led to a decrease in global temperatures and a reduction in sunlight. This had a negative impact on plant and animal life, and it is believed that the Toba Supereruption may have contributed to a near-extinction event for humans.
