Beneath Yellowstone, A Volcano That Could Wipe Out U.S.

” 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.” “

 

 

 

 

 

 

 

 

Why Have 10 Major Volcanoes Along The Ring Of Fire Suddenly Roared To Life?

 

 

 

” Ten major volcanoes have erupted along the Ring of Fire during the past few months, and the mainstream media in the United States has been strangely silent about this.  But this is a very big deal.  We are seeing eruptions at some volcanoes that have been dormant for decades.  Yes, it is certainly not unusual for two or three major volcanoes along the Ring of Fire to be active at the same time, but what we are witnessing right now is highly unusual.  And if the U.S. media is not concerned about this yet, the truth is that they should be.  Approximately 90 percent of all earthquakes and approximately 80 percent of all volcanic eruptions occur along the Ring of Fire, and it runs directly up the west coast of the United States.  Perhaps if Mt. Rainier in Washington state suddenly exploded or a massive earthquake flattened Los Angeles the mainstream media would wake up.  Most Americans have grown very complacent about these things, but right now we are witnessing volcanic activity almost everywhere else along the Ring of Fire.  It is only a matter of time before it happens here too.

Sadly, most Americans cannot even tell you what the Ring of Fire is.  The following is how Wikipedia defines the “Ring of Fire”…

The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.  It has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes.”

” The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian’s Global Volcanism Program and the US Geological Survey’s Volcano Hazards Program. Updated by 2300 UTC every Wednesday, notices of volcanic activity posted on these pages are preliminary and subject to change as events are studied in more detail. This is not a comprehensive list of all of Earth’s volcanoes erupting during the week, but rather a summary of activity at volcanoes that meet criteria discussed in detail in the “Criteria and Disclaimers” section. Carefully reviewed, detailed reports on various volcanoes are published monthly in the Bulletin of the Global Volcanism Network.”

 

   More information on global volcanic activity may be found at the USGS volcano site  and while we are on the topic of unusual seismic activity let us consider the strange doings in the Yellowstone caldera of Wyoming and Montana . Seismic activity in the form of earthquakes and tremors are also increasing in frequency in recent months . See map below .

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. “
