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]
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.
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.

Satellite image of Lake Toba, the site of a VEI 8 eruption c. 75,000 years ago Cross-section through Long Valley Caldera. Supervolcanoes occur when magma in the mantle rises into the crust but is unable to break through it. Pressure builds in a large and growing magma pool until the crust is unable to contain the pressure and ruptures.
Lake Toba, the world's largest volcanic lake and the largest lake in Southeast Asia, is in Indonesia This is a list of the notable lakes of Indonesia. Indonesia has 521 natural lakes and over 100 reservoirs, covering approximately 21,000 km 2. The total volume of water held is approximately 500 km 3. The largest lake, by both area and volume, is Lake Toba in Sumatra. It holds 240 km 3 of ...

The largest is the supervolcano Toba within the 100 km (62 miles) × 30 km (19 miles) Lake Toba, which was created after a caldera collapse (est. in 74,000 Before Present). [3] The eruption is estimated to have been at level eight on the VEI scale, the largest possible for a volcanic eruption.
