Be very afraid!

If we are able to survive a supervolcano eruption, then it'll be a marvel to watch it! Otherwise, God save us all!

In the meantime, if you don't know this already, there are 6 in the world that's due to erupt, 3 of them are in the U.S.!
  1. The Yellowstone (The most dangerous of them all)
  2. Long Valley (Eastern California, adjacent to Mammoth Mountain)
  3. Valles Caldera (Northern New Mexico)

 The other 3 are in Japan, Indonesia and New Zealand respectively.
  1. Kagoshima
  2. Lake Toba (The last one to erupt 74000 years ago!)
  3. Lake Taupo

 There are a total of 40 known supervolcanoes in the world. Most of them are dormant.

There was a documentary some 5 or 6 years ago by Discovery Channel on this matter. If you haven't seen it already, it's worth your time!

It's going to erupt, one of these supervolcanoes. No one knows when or which of the 6. However, when it happens, it might just be the end of civilization!

 I'm rating these supervolcanoes as a +5 instead of -5 because these are truly beautiful places. It's the eruption that's going to be real bad. Otherwise, I've been to 4 of them and survived the visits. Just hope that we won't see them erupt in our lifetime!
Be very afraid! Be very afraid! Be very afraid! Be very afraid! Be very afraid! Be very afraid!

I watched the doc you are talking about and man that is going to be crazy.

I know! I watched several shows in Discovery about the magnitude of the damage this may cause...pretty scary. They've allowed geysers to help relieve its pressure but we won't know. I remember Mt. Pinatubo, dormant for 200 years and! what an eruption.

The last one erupted some 74,000 years ago at Lake Toba, Sumatra, Indonesia. That's where my childhood playground was! Yellowstone is expected to erupt anytime soon or possibly not in the next few lifetime. It's due for one though.

About this topic


supervolcano is a volcano capable of producing a volcanic eruption with ejecta greater than 1,000 cubic kilometers (240 cubic miles). This is thousands of times larger than most historic volcanic eruptions.[1] Supervolcanoes can occur when magma in the Earth rises into the crust from a hotspot but is unable to break through the crust. Pressure builds in a large and growing magma pool until the crust is unable to contain the pressure. They can also form at convergent plate boundaries (for example, Toba) and continental hotspot locations (for example, Yellowstone).

The Discovery Channel highlighted six known supervolcanoes:[2] the YellowstoneLong Valley, and Valles Caldera in the United StatesLake TobaNorth SumatraIndonesiaTaupo VolcanoNorth IslandNew Zealand; and Aira CalderaKagoshima PrefectureKyūshūJapan. Although there are only a handful of Quaternary supervolcanoes, supervolcanic eruptions typically cover huge areas with lava and volcanic ash and cause a long-lasting change to weather (such as the triggering of a small ice age) sufficient to threaten theextinction of species.
