The world’s largest supervolcano erupted some time between 69,000 and 77,000 years ago, in one of the Earth’s largest eruptions ever. The eruption changed the weather dramatically, causing a 6 – 10 year winter, and possibly even leading to a 1000 year long cooling period. The shift in weather was enough to cause the human population of Earth to decline dramatically.
The volcano is located at Lake Toba on the island of Sumatra, in Indonesia. Its big blow was even bigger than the giant Yellowstone eruption 2.2 million years ago, and threw 2,800 cubic kilometres of volcanic ash and lava into the atmosphere. In today’s world, Indonesia is a very densely populated country, and 50 million people live in Toba’s shadow. These people would be immediately affected by another eruption, and in addition, Toba is located only 40 kilometers from the Indian Ocean, very close to where the catastrophic 2004 tsunami was generated to then spread across the world.
In recent months there have been reports in the Indonesian press of volcanic gases and heating of the ground surface, which has led to speculation that the Lake Toba super volcano might be getting ready to blow its top again. Stay tuned!
