Michael Snyder: Yellowstone supervolcano rumblings; reasons to be watchful

Important Takeaways:

  • Is it possible that the Yellowstone supervolcano is gearing up for a major eruption? When most people think of Yellowstone, they tend to conjure up images of “Old Faithful”, Yogi Bear and a television show starring Kevin Costner.  But the reality of the matter is that Yellowstone poses a very serious threat to all of us.  Yellowstone National Park in Wyoming is actually sitting directly above a massive supervolcano.
  • So when Yellowstone shakes, that should definitely get our attention.
  • In late January, a magnitude 3.9 earthquake was keenly felt throughout Yellowstone National Park…
  • Subsequently, there were two very alarming earthquake swarms in the area during the month of February…
  • February seismicity in Yellowstone was marked by two swarms.
    • A swarm of 18 earthquakes was located approximately 13 miles south-southwest of Mammoth, in Yellowstone National Park, during February 1–8. The largest earthquake in the sequence was a magnitude 1.6 on February 3 at 1:24 AM MST.
    • A swarm of 11 earthquakes took place approximately 5 miles south-southeast of West Thumb, in Yellowstone National Park, on February 11. The largest earthquake in the sequence was a magnitude 2.4 on February 11 at 1:44 AM MST.
  • I want to be very clear about something.
  • There is absolutely no reason to panic at this stage.
  • But I do believe that we should be watching.
  • So exactly what would a full-blown eruption of the Yellowstone supervolcano mean for the United States and for the rest of the world?
    • The magma “hotspot” underneath Yellowstone is approximately 300 miles wide.
    • A full-blown eruption of Yellowstone could be up to 1,000 times more powerful than the eruption of Mount St. Helens in 1980.
    • According to Google AI, a full-blown eruption of Yellowstone could send volcanic ash “up to 30-50 miles high”.
    • According to Wikipedia, the Yellowstone Caldera has been “rising as quickly as 150 millimeters (5.9 in) per year”.
    • There are more than a thousand earthquakes in the Yellowstone area every single year.
    • In the event of a full-blown eruption of Yellowstone, virtually the entire northwest United States will be completely destroyed
    • A full-blown eruption of Yellowstone would mean that just about everything within a 100-mile radius of Yellowstone would be immediately killed.
    • A full-blown eruption of Yellowstone could potentially dump a layer of volcanic ash that is at least 10 feet deep up to 1,000 miles away.
    • 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.  This would result in a horrific global famine.
    • 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.
    • Scientists tell us that it is not a matter of “if” Yellowstone will erupt again but rather “when” the next inevitable eruption will take place.
