The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago, during the Late Pleistocene, [2] at the site of present-day Lake Toba, in Sumatra, Indonesia.
Location of Lake Toba shown in red on map. The Toba eruption (the Toba event) occurred at what is now Lake Toba about 73,700±300 years ago. [15] It was the last in a series of at least four caldera-forming eruptions at this location, with the earlier known caldera having formed around 1.2 million years ago. [16]
A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles). [2] Location of Yellowstone hotspot over time. Numbers indicate millions of years before ...
About 74,000 years ago, Sumatra’s Mount Toba experienced a super-eruption, one of the largest in Earth’s history, potentially kicking off a massive disruption in the world’s climate.
Samosir, or Samosir Island, is a large volcanic island in Lake Toba, located in North Sumatra Province on the island of Sumatra in Indonesia. Administratively, Samosir Island is governed as six of the nine districts within Samosir Regency. The lake and island were formed after the eruption of the Toba supervolcano some 75,000 years ago.

The largest volcano of Sumatra is the supervolcano Toba within the 100 km (62 mi) × 30 km (19 mi) Lake Toba, which was created after a caldera collapse (est. in 74,000 Before Present). [2] The eruption is estimated to have been at level eight on the VEI scale, the highest level for a volcanic eruption.
The most recent eruption, which occurred 70,000 years ago was among the largest known eruptions ever. Uluan is located on the Porsea caldera, a part of the volcano that erupted approximately 800,000 years ago. [1] Parapat, the primary transit point for tourists going across the lake to Samosir Island, is located on Uluan.
