supervolcano
The caldera that covers most of Yellowstone Park was produced by a supervolcano. A supervolcano is an explosive volcano capable of producing an eruption with an ejecta volume greater than 1,000 cubic kilometers. The Yellowstone Caldera is one of the largest and most active supervolcanoes in the world.
How hot is the Yellowstone hotspot? At 80 kilometres beneath the Earth's surface it's about 1450 °C, say researchers - which, for a supervolcano, is only lukewarm.That doesn't mean we won't get http://wiki.answers.com/article/dn12896-magma-surge-causes-record-rise-at-yellowstone.html.

Yellowstone is different from most other volcanoes in two ways. First, it can produce enormous eruptions that only a handful of volcanoes have produced in the past few million years. Second, it covers such a large area that it has not built up a mountain and is instead identified by an enormous depression called a caldera left behind by its last super eruption.

Because it's not officially a 'dead' volcano - it's just dormant. Additionally, the caldera covers such a vast area that, in the event of a 'super eruption', the amount of material ejected would affect the Earth for centuries to come. Possibly resulting in the extinction of all life on this planet !
The Yellowstone National Park covers 2,219,789 Acres.
The Eyjafjallajökull is an ice cap in Iceland. It has come into the public view over the past couple months because it covers the caldera of the volcano that has errupted twice this year (2010) disrupting air traffic accross Europe.
