” A team from the University of Utah have told the American Geophysical Union Fall Meeting in San Francisco that Yellowstone’s magma chamber is 2.5 times larger than previously thought.

  It is an underground cavern measuring some 55 miles by 20 miles and containing between 125 and 185 billion cubic miles of molten rock.

  If it blows it will wipe out America – and have enormous impacts on the rest of the world.

  The university researchers described their discovery as “astounding.”

  Professor Bob Smith told the BBC: “We’ve been working there for a long time, and we’ve always thought it would be bigger … but this finding is astounding.” “

 

 

 

 

 

 

 

 

The Most Dangerous Volcano In America Is Roaring To Life

 

” Right now, the ground underneath Yellowstone National Park is rising at a record rate.  In fact, it is rising at the rate of about three inches per year.  The reason why this is such a concern is because underneath the park sits the Yellowstone supervolcano – the largest volcano in North America.  Scientists tell us that it is inevitable that it will erupt again one day, and when it does the devastation will be almost unimaginable.  A full-blown eruption of the Yellowstone supervolcano would dump a 10 foot deep layer of volcanicash up to 1,000 miles away, and it would render much of the United States uninhabitable.  When most Americans think of Yellowstone, they tend to conjure up images of Yogi Bear and “Old Faithful”, but the truth is that sleeping underneath Yellowstone is a volcanic beast that could destroy our nation in a single day and now that beast is starting to wake up.”

” The Yellowstone supervolcano is so vast that it is hard to put it into words.  According to the Daily Mail, the magma “hotspot” underneath Yellowstone is approximately 300 miles wide…

The Yellowstone Caldera is one of nature’s most awesome creations and sits atop North America’s largest volcanic field.

Its name means ‘cooking pot’ or ‘cauldron’ and it is formed when land collapses following a volcanic explosion.

In Yellowstone, some 400 miles beneath the Earth’s surface is a magma ‘hotspot’ which rises to 30 miles underground before spreading out over an area of 300 miles across.

Atop this, but still beneath the surface, sits the slumbering volcano.”

Well, according to the Daily Mail, a full-blown eruption of Yellowstone could leave two-thirds of the United States completely uninhabitable…

It would explode with a force a thousand times more powerful than the Mount St Helens eruption in 1980. “
