Beneath the Pacific Ocean is growing supervolcano


February 13, 2013. According to the Huffington UK, U.S. researchers from the University of Utah found at the bottom of the Pacific Ocean supervolcano, which is able to destroy the Earth.

Scientists say that two chemical bladder the size of a continent of partially molten rock, converge beneath the Pacific Ocean, and it seems that will create new supervolcano.

It can bring the world scale disaster.

Geologist Michael Thorne of the University of Utah in the message for Earth and Planetary Science, says that the collision takes place slowly at a depth of 2900 km under the ocean. He predicts that the collision can lead to two possible scenarios. And both with a bad end, as the lead to the destruction of millions of species. The first scenario — a giant eruption that will kill us all. The second — the thousand, by duration, flood basalt eruptions, which also kill us.

The problem is that the two huge "thermochemical piles" of molten rock, about 4830 km in diameter are moving towards each other at the bottom of the mantle. Their existence has been known for decades, but initially it was thought that they are static. But after extensive research of seismic waves, Thorne made sure that they are actually moving at the same time. As a result, a huge molten bubbles once under the ocean will create enormous pressure, which, ultimately, will lead to an explosion on the surface.

"The fact that we may be found to be the beginning of one of these large eruptive events, which — if it occurs — can be lead a very massive destruction on Earth "- said Thorne.

Fortunately, the process is slow — it takes about 100 million years or so.

And anyway, there are other supervolcanoes that are worth worrying to begin with.
