In a regular volcano eruption, scorching magma shoots up from the bottom of the earth. As the magma cools, it creates a cone shape that gradually forms into a mountain. In super volcanoes, the magma gets blocked from getting to the exterior surface. Instead, the amount of pressure just increases over time until more gravel in the region melt and turn into magma too. The area beneath the exterior surface becomes an enormous underground sea of magma and when the pressure gets too much to handle, a giant explosion that’s a thousand times more intense than a regular volcano bursts causing massive cataclysmic destruction.

Consequences 
An eruption from this supervolcano could have numerous catastrophic outcomes. It is estimated that 5 miles below the surface of the Yellowstone caldera lays a pit of magma measuring 30 miles long and 20 miles wide. With the amount of pressure contained within the supervolcano, which is already visible through its cycles of hourly “mini-eruptions”, the release of this amount of hot magma could decimate North America. It’s effects could reach across the world however.

Eruption of super volcano

Super volcanoes are no ordinary volcanoes. They are substantially larger than the common volcano and produce the biggest and most deadly eruptions on earth. The strength of these eruptions ranges, but the wide amount of magma is massive enough to drastically change the earth’s surface and seriously affect the worldwide climate for many years and a possible threat to eliminate a large human population on earth. So far, there have been 2 kinds of volcanic eruptions that have been discovered as a super volcano, and the last identified eruption was located in Toba, Indonesia about 74,000 years ago. The amount of force in the explosion was calculated to be 10,000 stronger than the volcanic eruption that destroyed Mount St. Helens. A large amount of rock and burning ash were in the air and blocked the sun for many months. The temperature on earth was believed to have dropped down to 21 degrees. Mankind was nearly pushed to the edge of extinction as the human population was reduced to a couple of thousand and 75% of plant life in the North American hemisphere was nearly wiped out.
