Geologist Michael Thorne of the University of Utah, says that at the bottom of the Earth's mantle is the convergence of two "thermochemical piles," the size of a continent each. This process, occurring at a depth of 2900 km below the surface of the Pacific Ocean, can lead to a massive eruption that would cause massive destruction on Earth.

But do not panic, at least right now. Scientists suggest that the supervolcano eruption will happen no earlier than 100 or even 200 million years. Findings will be published researcher in the February issue of the journal Earth and Planetary Science Letters, reports portal IO9.
According to calculations by Thorne, the collision of two "piles" leads to the formation of a huge reservoir partially molten rock that in the future may cause superizverzheniya.
One of the possible scenarios — a large-scale geological event that occurred about two million years ago in the Yellowstone caldera, resulting in all of North America was covered with volcanic ash. The second option — a more extended in time an event called trap eruption, which often lack a clearly defined center of the crater and the constant eruptions.
