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. Numbers indicate millions of years before ...
Mount Tambora is a volcano on the island of Sumbawa in present-day Indonesia, then part of the Dutch East Indies, [2] and its 1815 eruption was the most powerful volcanic eruption in recorded human history. This volcanic explosivity index (VEI) 7 eruption ejected 37–45 km 3 (8.9–10.8 cubic miles) of dense-rock equivalent (DRE) material into ...
Mount Tambora, or Tomboro, is an active stratovolcano in West Nusa Tenggara, Indonesia. Located on Sumbawa in the Lesser Sunda Islands, it was formed by the active subduction zones beneath it. Before 1815, its elevation reached more than 4,300 metres (14,100 feet) high, making it one of the tallest peaks in the Indonesian archipelago.
About 33.9 million ago, the Oligocene epoch of the Paleogene period begins. The Mid-Tertiary ignimbrite flare-up begins 40 million years ago and lasts until 25 million years ago. Bennett Lake Volcanic Complex erupts 50 million years ago with a VEI 7 850 cubic kilometers (204 cu mi) of tephra.
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.
Hike / auto / bus. The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming. The caldera measures 43 by 28 miles (70 by 45 ...
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 ...
A large area of the Sunda Strait and places on the Sumatran coast were affected by pyroclastic flows from the volcano. Verbeek and others believe that the final major Krakatoa eruption was a lateral blast, or pyroclastic surge. Material shot out of the volcano at 2,575 kilometres per hour (715 metres per second). [10]
