Is there a VEI 8?
No VEI-8 eruption has occurred in recent human history. The most recent such eruption is the Oruanui eruption that formed Lake Taupō, roughly 26,500 years before present.
What Vei is a supervolcano?
The term “supervolcano” implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning that at one point in time it erupted more than 1,000 cubic kilometers (240 cubic miles) of material.
What would a VEI 8 eruption be like?
Such eruptions release a tephra volume of at least 1,000 km3 (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. …
How many Vei 8 eruptions have there been?
This geologic superstar has had at least three very large eruptions in its history: Two are super-eruptions that were VEI 8 (some 2.1 million and 640,000 years ago), and one eruption 1.3 million years ago was VEI 7, producing around 67 cubic miles of material.
How many Vei 8 volcanoes are there?
Eruptions at Toba (74,000 years ago), Yellowstone (640,000 years ago), and Lake Taupo (26,500 years ago) are three of the 47 VEI 8 sites that have been identified.
When did Vei 8 last erupt?
around 75,000±900 years ago
This last major eruption occurred around 75,000±900 years ago and had an estimated VEI= 8, making it the largest-known explosive volcanic eruption within the last 25 million years. An estimated 2,800 km3 of dense-rock equivalent pyroclastic material, known as the youngest Toba tuff, was released.
Where are Earth’s Supervolcanoes?
Three of the seven supervolcanoes are located in the continental US: Yellowstone, the Long Valley Caldera, and the Valles Caldera.
- The most well known supervolcano is in Yellowstone National Park, Wyoming (shown above).
- Moving southwest into the Inyo National Forest of California is the Long Valley Caldera.

The latest VEI 7 event, at Tambora, Indonesia, in CE 1815, was at the low end of VEI 7 eruptions. Its global effects were widely reported (Stommel and Stommel, 1983; Stothers, 1984; Harington, 1992; de Jong Boers, 1995; Oppen- heimer, 2003a; Raible et al., 2016).
Are there any VEI-8 volcanoes?
