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.

The Misema Caldera is in the order of 3,500 to 4,000 km 2 (1,400 to 1,500 sq mi), making the complex similar to the Yellowstone Caldera in Wyoming, Lake Toba in Indonesia and strikingly similar in structure to the Olympus Mons caldera on Mars. [2] As a result, the Blake River Group is best categorized as a meganested caldera complex. [3]
A volcanogenic lake is a lake formed as a result of volcanic activity. [1] They are generally a body of water inside an inactive volcanic crater ( crater lakes ) but can also be large volumes of molten lava within an active volcanic crater ( lava lakes ) and waterbodies constrained by lava flows, pyroclastic flows or lahars in valley systems.

The lake and island were formed after the eruption of the Toba supervolcano some 75,000 years ago. [2] At 630 square kilometres (243 sq mi), Samosir is the largest island within an island and the fourth largest lake island in the world. [3] It also contains two smaller lakes, Lake Sidihoni and Lake Aek Natonang .
Landsat image of Lake Toba, Indonesia, the largest volcanic crater lake in the world. A well-known crater lake, which bears the same name as the geological feature, is Crater Lake in Oregon. It is located in the caldera of Mount Mazama. It is the deepest lake in the United States with a depth of 594 m (1,949 ft).
