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.
How many Supervolcanoes are there?
There are about
12 supervolcanoes
on Earth — each one at least seven times larger than Mount Tambora, which had the biggest eruption in recorded history. If all of these supervolcanoes erupted at once, they'd likely pour thousands of tons of volcanic ash and toxic gases into the atmosphere.
What is the difference between a volcano and a supervolcano?
A supervolcano is a volcano on a massive scale. It is different from a volcano because:
a supervolcano erupts less frequently – eruptions are hundreds of thousands of years apart
.
What are super volcanoes and how are they formed?
Supervolcanoes occur
when magma in the mantle rises into the crust and is unable to break through a fissure or vent
. Over time, immense pressures start to accumulate in a growing magma pool until it explodes through the crust violently.

What volcano could destroy the world?
The Yellowstone supervolcano
is a natural disaster that we cannot prepare for, it would bring the world to its knees and destroy life as we know it. This Yellowstone Volcano has been dated to be as old as 2,100,000 years old, and throughout that lifetime has erupted on average every 600,000-700,000 years.
Is Mt St Helens a supervolcano?
Mt. Saint Helens is not even the most likely volcano in the Cascades to produce a
“supervolcanic” eruption
. It has been very active over the last 10,000 years, but most tend to be small, bleeding out material frequently over this period.

What is the most likely supervolcano to erupt?
Over the past 640,000 years since the last giant eruption at
Yellowstone
, approximately 80 relatively nonexplosive eruptions have occurred and produced primarily lava flows. This would be the most likely kind of future eruption.
Is Yellowstone due to erupt?

Yellowstone is going to erupt
. It has erupted before and it will erupt again. Scientists have been studying the Supervolcano at Yellowstone for a long time, and piecing the studies together gives us a glimpse of what things will be like next time Yellowstone erupts.

What would happen if you dropped a nuke into a volcano?
If you dropped a nuclear bomb into the crater of an extinct volcano, you would
flatten the mountain out a bit
