Weekly Post: Volcano Unit-Super eruptions


So we all know that Yellowstone's eruptions are VEI 8, or supervolcanic, but I was wondering what other Super Volcanoes there are out there. So, I looked it up. Here's the recorded super eruptions.

1. Lake Taupo, New Zealand,-Oruanui eruption- 26,500 years ago.
2. Lake Toba, Sumatra, Indonesia- 74,000 years ago.
3. Whakamaru North Island, NEw Zealand- 254,000 years ago.
4. Yellowstone, Wyoming, US- 640,000 years ago.
5. Island Park Caldera, Idaho/Whyoming, US- 2.1 million years ago.
6. Kilgore Tuff, Idaho, US- 4.5 million years ago.
7. Blacktail Creek, Idaho, US- 6.6 million years ago.
8. La Garita Caldera, Colorado, US- 27.8 million years ago.

I never thought of the US as a very volcanic place but over half of the recorded supervolcanic eruptions have happened here.
