A supervolcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1000 km cubed. This is about 1000 times bigger than a normal volcanic eruption. super volcanos don’t tend to be visible from the ground as they are so big. This is because the caldera, a large volcanic crater, are so big, in the case of Yellowstone it is over 40 miles across, so people do not recognize it as a volcano. Super volcanos occur when magma in the mantle rises into the crust from a hotspot but is unable to break through the crust, due to this pressure builds in a large and growing magma pool until the crust is unable to contain the pressure, this is what will and is happening at the Yellowstone caldera. These can also be formed at convergent plate boundaries, this is what is happening at Toba.
What is now known as Yellowstone super volcano is situated in the united states of america, in the north-west states of Wyoming, Idaho and Montana, it is situated on the borders of these three states, in Yellowstone national park. Yellowstones most recent eruptions have been 2.1 million, 1.3 million and 640,000 years ago, and another one is due around now. The yellowstone super volcano has slowly been moving up from the bottom of Idaho and has been growing in size during the last 12 million years.
The local effects of a super volcanic eruption would mainly be extremely high lava and ash deposits, this would affect around 100 miles around the volcano and would cause total destruction of everything in the area, and this would cause untold environmental, social and economic problems in the area, with the majority of people being killed in the eruption. The national effects of the eruption if it did take place within our lifetimes would destroy about 10,000 km squared of land, ash would fall 15 cm thick on every thing within 1000 km of the eruption, it is also predicted that it would kill 87,000 people, 1 in 3 people that were affected would die, again this
