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.
Toba Caldera is one of twenty geoparks in Indonesia, [2] and was recognised in July 2020 as one of the UNESCO Global Geoparks. [3] [4] [5] Lake Toba is the site of a supervolcanic eruption estimated at VEI 8 that occurred 69,000 to 77,000 years ago, [6] [7] [8] representing a climate-changing event.
It has experienced a large amount of uplift because of a series of massive volcanic eruptions that began 1.2 million years ago. 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]
The Yellowstone Caldera formed over 600,000 years ago from the Lava Creek Tuff eruption, which was measured on the Volcanic Explosivity Index as an 8, according to the U.S. Geological Survey ...
Volcanoes that have produced explosive VEI-8 eruptions, often called supervolcanoes in the media. Such eruptions release a tephra volume of at least 1,000 km 3 (240 cu mi) with annihilating long-term effects on the surrounding area and devastating short-term effects on global climate, leaving profound effects on the climate for years to come.
Toba supereruption Pleistocene human population bottleneck Toba catastrophe theory Bcndz5 09:28, 5 April 2023 (UTC) Maybe, considering that recent studies on the Toba supereruption have dramatically increased its volume estimates, and has been mentioned to be among the largest ignimbrites ever discovered.
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.
