Toba is the number one largest lake in Indonesia with a surface area of ​​about 1,130 km². The lake, which is located in the middle of North Sumatra, is also touted as the largest volcanic lake in the world.

That said, the basin was formed from a volcanic eruption that erupted more than 70 thousand years BC. The eruption is considered the largest on Earth, so it is said to be the trigger for an ice age (the time when Earth’s temperature drops and causes the amount of ice at the poles to increase).

Researchers from Michigan Technological University, Bill Rose and Craig Chesner estimated, the total amount of eruptive material reached 2,800 km. As a result, there was mass death and the extinction of several species of living things, as well as shrinking about 60 percent of the total human population on Earth at that time which was approximately 60 million humans.

The lake, which is between 1-4 million years old, was formed from faults caused by tectonic activity. Interestingly, in the middle of the surface there are several small islands, including Loeha, Bolong, and Pulau Kembar.
