A Supervolcano is a volcano characterized by the large area it affects. A supervolcano is generally accepted to be a volcano that discharges ash, lava, or pumis deposits that spread over 240 or more cubic miles from its center. The Indonesian Toba is an example of a supervolcano.

Where are the most destructive volcaanoes?
Supervolcanoes. There is one under Yellowstone National Park [See related link]
Will there be a supervolcano in 2012?
No. No supervolcanoes are expected to erupt any time in our lifetimes. However, ordinary volcanoes erupt every year.
Where do the deadliest volcanoes mostly occur?
The deadliest volcanoes are the so-called "supervolcanoes", which can cover an entire continent in volcanic ashes. They erupt perhaps once every 100,000 years on average. They are all over the world; for example, there is one in Yellowstone Park. For a list of additional known supervolcanoes, read the Wikipedia article on "Supervolcano". Or some other online source.
What are super volcaneos?
Supervolcanoes are large volcanic systems capable of producing extremely explosive eruptions with the potential to have global consequences. They are characterized by the presence of a magma chamber beneath the Earth's crust, which can lead to massive caldera formations when eruptions occur. Examples include Yellowstone in the United States and Toba in Indonesia. The eruptions of supervolcanoes can release vast amounts of ash and gases, significantly affecting climate and ecosystems.
Was there a super volcano in the lake district?
The answer is, yes, there was. About 40 supervolcanoes are dotted across the globe. There are two in Britain - one in Glencoe, Scotland, the other in Scafell in the Lake District. However, most supervolcanoes, including those in Britain, burned out long ago.http://www.bbc.co.uk/sn/tvradio/programmes/supervolcano/article.shtml
What are supervolcanies?
Supervolcanoes are extremely powerful volcanic eruptions, capable of covering an entire continent in ashes, and significantly changing the world climate for years. These events are believed to have occured several times in the past.
Is it possible to harness a supervolcanoes power?
Their unpredictability in a number of areas makes it impossible at this time to harness the actual power of eruption, although geothermal can be harnessed by tapping into the heat and steam that are created in associated structures.
Are there any supervolcanoes on mars?
At present there is no observed volcanic activity of Mars. The super volcano of Olympus Mon on Mars is thought to be inactive, dating its past eruption from several to 15+ million years ago.
Why do supervolcanoes occur?
super volcanoes can occur when the magma rises into the crust from a hotspot but is unable to breakthrough the crust. Pressure builds in a large and growing magma pool until the crust is unable to contain the pressure.
Why is Yellowstone volcano and Vesuvius being so closely monitored?
They are supervolcanoes. If they erupt, we simply have had it. Happened a couple of times in the last million years and always brought life on this planet to the verge of extinction. Forget about nuclear winter and mutually assured destruction ... this is gonna be worse ...
What is the difference between a super-volcano and a regular volcano?
The main difference between the two is size. Supervolcanoes are normally 30 times stronger that a regular volcano and can produce enough ash to cover the world. A supervolcano is a VEI8, and ejects over 1 trillion tons of material. Also, supervolcanoes don't have the cone shape.
