Yellowstone Supervolcano Alert: The Most Dangerous Volcano In America Is Roaring To Life Right Now, The Ground Underneath Yellowstone National Park Is Rising At A Record Rate. By Michael SnyderIn 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 volcanic ash 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.When most Americans think of volcanic eruptions in the United States, they remember the catastrophic eruption of Mount St. Helens back in 1980. But that eruption would not even be worth comparing to a full-blown eruption of the Yellowstone supervolcano.And now the area around Yellowstone is becoming increasingly seismically active. In fact, Professor Bob Smith says that he has never seen anything like this in the 53 years that he has been watching Yellowstone…Until recently, Bob Smith had never witnessed two simultaneous earthquake swarms in his 53 years of monitoring seismic activity in and around the Yellowstone Caldera.Now, Smith, a University of Utah geophysics professor, has seen three swarms at once.In September, 130 earthquakes hit Yellowstone over the course of a single week. This has got many Yellowstone observers extremely concerned…Yellowstone’s recent earthquake swarms started on Sept. 10 and were shaking until about 11:30 a.m. Sept. 16.“A total of 130 earthquakes of magnitude 0.6 to 3.6 have occurred in these three areas, however, most have occurred in the Lower Geyser Basin,” a University of Utah statement said. “Notably much of seismicity in Yellowstone occurs as swarms.”So what is the worst case scenario?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.Spewing lava far into the sky, a cloud of plant-killing ash would fan out and dump a layer 10ft deep up to 1,000 miles away.Two-thirds of the U.S. could become uninhabitable as toxic air sweeps through it, grounding thousands of flights and forcing millions to leave their homes.Can you think of another potential disaster that could accomplish the same thing?That is why what is going on at Yellowstone right now is so important, and the American people deserve the truth. The following are some more facts about Yellowstone that I compiled that I included in a previous article…#1 A full-scale eruption of Yellowstone could be up to 1,000 time more powerful than the eruption of Mount St. Helens in 1980.#2 A full-scale eruption of Yellowstone would spew volcanic ash 25 miles up into the air.#3 The next eruption of Yellowstone seems to be getting closer with each passing year. Since 2004, some areas of Yellowstone National Park have risen by as much as 10 inches.#4 There are approximately 3,000 earthquakes in the Yellowstone area every single year.#5 In the event of a full-scale eruption of Yellowstone, virtually the entire northwest United States will be completely destroyed.#6 A massive eruption of Yellowstone would mean that just about everything within a 100 mile radius of Yellowstone would be immediately killed.#7 A full-scale eruption of Yellowstone could also potentially dump a layer of volcanic ash that is at least 10 feet deep up to 1,000 miles away.#8 A full-scale eruption of Yellowstone would cover virtually the entire midwest United States with volcanic ash. Food production in America would be almost totally wiped out.#9 The “volcanic winter” that a massive Yellowstone eruption would cause would radically cool the planet. Some scientists believe that global temperatures would decline by up to 20 degrees.#10 America would never be the same again after a massive Yellowstone eruption. Some scientists believe that a full eruption by Yellowstone would render two-thirds of the United States completely uninhabitable.#11 Scientists tell us that it is not a matter of “if” Yellowstone will erupt but rather “when” the next inevitable eruption will take place.What makes all of this even more alarming is that a number of other very prominent volcanoes around the world are starting to roar back to life right now as well.For example, an Inquisitr article from back in July described how “the most dangerous volcano in Mexico” is starting to become extremely active…Popocatepetl Volcano is at it again. The active volcano near Mexico City erupted again this morning, spewing ash up into the sky.The volcano is currently in the middle of an extremely active phase. According to the International Business Times, the volcano has registered 39 exhalations in the last 24 hours.An eruption earlier this month caused several flights to be canceled in and out of Mexico City.The BBC notes that officials raised the alert level yellow following Popocateptl’s eruption on Saturday morning. Yellow is the third-highest caution level on the city’s seven step scale.And an NBC News article from August noted that one of the most dangerous volcanoes in Japan has erupted 500 times so far this year…Ash wafted as high as 3 miles above the Sakurajima volcano in the southern city of Kagoshima on Sunday afternoon, forming its highest plume since the Japan Meteorological Agency started keeping records in 2006. Lava flowed just over half a mile from the fissure, and several huge volcanic rocks rolled down the mountainside.Though the eruption was more massive than usual, residents of the city of about 600,000 are used to hearing from their 3,664-foot neighbor. Kagoshima officials said in a statement that this was Sakurajima’s 500th eruption this year alone.So what does all of this mean?Are we now entering a time when volcanic eruptions will become much more common all over the globe?Could we rapidly be approaching the day when an absolutely devastating volcanic eruption will paralyze much of North America?
