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.
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.
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]

Mount Emmons, Mount Hague, and Double Crater are post-caldera cones. [6] The topography of the Basin and Range Province is a result of crustal extension within this part of the North American Plate (rifting of the North American craton or Laurentia from Western North America; e.g. Gulf of California, Rio Grande rift, Oregon-Idaho graben).
The Year Without a Summer was an agricultural disaster; historian John D. Post called it "the last great subsistence crisis in the Western world". [4] [5] The climatic aberrations of 1816 had their greatest effect on New England, Atlantic Canada, and Western Europe.
