Do you believe in super volcanoes?

Answer 1

Supervolcanoes are volcanic eruptions where more than 1000 cubic kilometers of material is extruded. As a comparison, the Mount Helens eruption amounted to 2.3 cubic kms.

The following locations are known to be supervolcanoes:

- Lake Toba, Sumatra, Indonesia - 75,000 years ago (2,800 km³)
- Yellowstone, United States - 2.2 million years ago (2500 km³) and 640,000 years ago (1000 km³)
-La Garita Caldera, Colorado, United States - 27.8 million years ago (over 5,000 km³)
-Bruneau-Jarbidge, Idaho, United States - 10-12 million years ago (responsible for the Ashfall Fossil Beds 1600 km to the east)

Answer 2

Whatever you mean by super volcanoes, yes. One only has to look back through recorded history to find huge eruptions. Super volcanoes, by definition have a long time between eruptions so one could go off at any time or not until we are long gone.

Answer 3

A supervolcano refers to a volcano that produces the largest and most voluminous kinds of eruption on Earth. The actual explosivity of these eruptions varies, but the sheer volume of extruded magma is enough to radically alter the landscape and severely impact global climate for years, with a cataclysmic effect on life.

Answer 4

the biggest volcano's are actually under the sea.there are mountains down there bigger than Everest.we know more about outer space than we do about the ocean floors.there are creatures down there that have not even been discovered yet.so why not super volcano's down there.in places the ocean is 12 miles deep.the Marianna's trench off the coast of Guam

Answer 5

The most recent (recorded) Super Vovano erupted in today's Indonesia in the late 1800. It is KRAKATAO.

The whole island basically gone and now it remain ( called ANAK KRAKKATAO ) still exist and still pose danger to the world, particularly people in Indonesia.

The Tsunami as a result of the eruption sent big wave to as far as America and Africa. The dust covered the sky for months in area near of 500km from it. Dust from the said eruption can also be traced until America.

In other word, it is a SMALL scale ELE (Extinction Level Event ).

Today, we don't know when ANAK KRAKKATAO ( meaning son of krakatao) will erupt. We all hope not in our time.

Answer 6

I think the super maybe the volcanoes Merapi, located in Yogyakarta, Indonesia

Answer 7

sure.. a super volcanoe is not a normal mountainous volcanoe you see in the distance, but one that is simmering under the earths crust just waiting to explode. when it does you would not want to be any where near it. it will EXplode and then form a caldera and IMplode. yellow stone national park is one.

Answer 8

Karaktoa 18 whenever, caused 50 years of global cooling due to the dust. Yes they exist, but seldom errupt.

There is no limit to the power of nature. There are several earthquakes a year with more power than the atomic bomb.

Answer 9

i know someone who was in a super volcano

Answer 10

i believe in not underestimating nature. There have been some big bangs in the past. There's less vulcanism now (phew) but no doubt there are still surprises in store.
