What is a supervolcano exactly?
I think the name says it all, but officially, scientists define it as a volcano capable of an eruption thousands of times greater than any ordinary volcanic explosion.
These supervolcanoes burst when a growing pressure of molten rock, or magma, rises up from the Earth’s mantle.
When the crust can’t contain the buildup anymore — boom.
The Yellowstone Super Volcano, as it is currently known, is believed by many to be of common source with the Columbia River Basalt eruptions which formed the Columbia R. Gorge. It was located beneath the Southern Oregon border region at that time, feeding a plume of hot and molten rock that produced “caldera” (giant volcanic crater) eruptions. This same plume, beginning about 2 million years ago, moved to and is now located underneath Yellowstone producing the Yellowstone Super Volcano, the most powerful & largest on the planet.
They are currently closely monitoring Yellowstone because of the intensifying geothermal activity and swarms of earthquakes in the area.
