The Toba eruption (sometimes called the Toba supereruption or 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. It was the last in a series of at least four caldera -forming eruptions at this location, with the ...
Lake Toba. Lake Toba (Indonesian: Danau Toba, Toba Batak: ᯖᯀᯬ ᯖᯬᯅ; romanized: Tao Toba) is a large natural lake in North Sumatra, Indonesia, occupying the caldera of the Toba supervolcano. The lake is located in the middle of the northern part of the island of Sumatra, with a surface elevation of about 900 metres (2,953 ft), the ...
The eruption of YTT from Toba Caldera, 74,000 years ago, is regarded as the largest known Quaternary eruption [38] and two orders of magnitude greater than the magma volume of the largest historical eruption, Tambora. [39] The exceptional magnitude of this freaky eruption has prompted sustained debate as to its global and regional impact on ...
Prediction of volcanic activity, and volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities.
An archaeological site in Ethiopia has revealed that a population of humans survived the eruption of Sumatra’s Mount Toba 74,000 years ago. One of the largest eruptions in Earth’s history ...
Resurgent dome. The caldera of Lake Toba, with a resurgent dome, forming Samosir Island. In geology, a resurgent dome is a dome formed by swelling or rising of a caldera floor due to movement in the magma chamber beneath it. Unlike a lava dome, a resurgent dome is not formed by the extrusion of highly viscous lava onto the surface, but rather ...
View of Lake Toba in Sumatra, Indonesia which is the largest volcanic lake in the world. 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 and waterbodies constrained by lava flows, pyroclastic flows or ...
A geological event such as massive flood basalt, volcanism, or the eruption of a supervolcano [177] could lead to a so-called volcanic winter, similar to a nuclear winter. Human extinction is a possibility. [178] One such event, the Toba eruption, [179] occurred in Indonesia about 71,500 years ago.
