Yellowstone Super Volcano: We May Have Far Less Advance Warning Time Than We Thought

A new study done on ancient volcanic ash revealed that we may experience an eruption of the Yellowstone supervolcano even sooner than previously warned. Scientists are also concerned that we will probably have much less advance warning time than we had thought before.

According to National Geographic, we may have mere decades before Yellowstone erupts. If the supervolcano underneath Yellowstone national park erupts again, we could also have far less time to prepare than originally thought. After analyzing minerals in fossilized ash from the most recent mega-eruption, researchers at Arizona State University think the supervolcano last woke up after two influxes of fresh magma flowed into the reservoir below the caldera. The new paper adds to the lengthening list of surprises scientists have uncovered over the last few years as they have continued to study and closely monitor the supervolcano.

A 2013 study, for instance, showed that the magma reservoir that feeds the supervolcano is about two and a half times larger than previous estimates. Scientists also think the reservoir is drained after every monster blast, so they thought it should take a long time to refill. Based on the new study, it seems the magma can rapidly refresh—making the volcano potentially explosive in the geologic blink of an eye. –National Geographic

“It’s shocking how little time is required to take a volcanic system from being quiet and sitting there to the edge of an eruption,” study co-author Hannah Shamloo told the New York Times. But scientists insist that this may seem scary, however, it may still be awhile before the eruption occurs.

About 630,000 years ago, a powerful eruption shook the region, spewing forth 240 cubic miles’ worth of rock and ash. The violent eruption created the Yellowstone caldera, a volcanic depression 40 miles wide that now cradles most of the national park. That eruption also left behind the Lava Creek Tuff, the ash deposit that Shamloo and her ASU colleague Christy Till used for their work. The two scientists presented their findings in August at a volcanology meeting in Oregon. The pair also presented an earlier version of their study at a 2016 meeting of the American Geophysical Union.

Based on fossil deposits like this one, scientists believe that the supervolcano has seen at least two other eruptions on this scale in the past two million years or so. Almost everyone who studies Yellowstone’s slumbering supervolcano says that right now, we have no way of knowing when the next big blast will happen. For its part, the U.S. Geological Survey puts the rough yearly odds of another massive Yellowstone blast at 1 in 730,000. That’s about the same chance as a catastrophic asteroid collision with earth.

Yellowstone is one of the best-monitored volcanoes in the world, notes Michael Poland, the current Scientist-in-Charge of the Yellowstone Volcano Observatory for the U.S. Geological Survey. A variety of sensors and satellites are always looking for changes, and right now, the supervolcano does not seem to pose a threat. “We see interesting things all the time … but we haven’t seen anything that would lead us to believe that the sort of magmatic event described by the researchers is happening,” says Poland via email, adding that the research overall is “somewhat preliminary, but quite tantalizing.”

  1. Yes……it could erupt in 7,000 years instead on 30,000 years. Do I run for the hills yet? LOL

  2. Yohan Smythe III says:

    The sooner the better

  3. buttcrackofdoom says:

    ho hum…i got plenty of time to prepare for THAT one…..it’s the FINANCIAL earthquake I’M worried about….hell, i’m about as prepared as i WANT to be.

  4. TEST says:

    Interestingly, a supervolcano went off under what is now known as Detroit several decades ago.

    Oh wait, scratch that! It was something much more destructive, called “socialism” that went off

  5. Prepared Pastor says:

    It has erupted before and I’m outside the legitimate impact map. Yes it could result in climate change, but the climate is always changing.

  6. Heartless says:

    Kind of like chili night around here – never know when things will erupt. Could be tonight, morning…. all I’ve learned to prove my analogy is that like lava, it’s just as hot going out as it was going in. Just takes a lot less time is all.

  7. aljamo says:

    A nuclear war is more worrisome than Yellowstone erupting to me anyway, evil stupid men would launch that attack on humanity. I trust nature more.

  8. Archivist says:

    I got two rolls of plastic and a lot of duct tape. And other stuff.

    I don’t think it’ll be too bad in eastern NC. We’ll just dust everything off and plow it under. Perhaps there will be some good minerals in the ash to amend the soil.

  9. Oh, goody. More Fear. I love fear. I eat so much fear it’s almost like an addiction now.
    I was getting worried that there wouldn’t be enough fear to go around but then this article appears. Assuaging my fear of the severe lack of fear.
    Fear for me, fear for you.
    Fear for three, fear for two.
    “I want the fear!”
    “You can’t handle the fear!”

  10. the blame-e says:

    Oh, God. Not the weekly “Run and hide! Run and hide!” update on the Yellowstone volcano. Boring.

    Mac Slavo, look, I understand. You have a job to do. But try, just try, to see it from your reader’s POV. I really don’t think you are aware of what happens if just one of these super mega volcanos erupts. There are ten (10) of them. Just one blowing, like Yellowstone, is an extinction event. There is the “put your head between your knees and kiss your a** goodbye,” and the frozen in place for all eternity Pompeian figures.

  11. War Thog says:

    If it were to happen, the MSM would blame it on Trump. Maybe NKorea will nuke Jellystone….?

  12. Jimbob 327 says:

    We All live one day at a time. A bigger concern is Where we go after death.
    God controls the planet. Volcano or no vacano, time moves on.
    Man has tried to help the earth. Some things failed miserably.

  13. Anticommie says:

    Odds are for Spock, gamblers and psychics. Reality is cause and effect. Everything is predestined. Things like vaginal, azzhole and volcanic size.
    Also explosions are predestined. They usually happen without warning and are kinda fast. Never seen a slo-mo explosion.
    Damn good to post drunk comments.

  14. Plan twice, prep once says:

    Humans are resilient. I’m still amazed at the relatively low death rate in Puerto Rico and other islands directly hit by recent hurricanes. Some islands were literally scrubbed flat of buildings, yet out of the wreckage people came climbing. The vast vast part of their populations survived unhurt.

    I have to say that had I not prepped for the big storm that hit me, I’d have still been fine, because I was prepped, we were sitting in relative luxury. Nighttime temperatures were running in the high thirties to low forties. Not freezing, but really uncomfortable for most people. We were warm, secure, had clean water, lots of food and a means to cook it.

  15. Traitor Hator says:

    Regarding ammo quantity for SHTF. If you have to shoot off one round per hour to scare off looters. That’s over 700 rounds the first month. Armed looters will take a lot more ?

  16. Sam W. says:

    All they seem to be saying is “Thanks for the reasech grant, we have no clue at all!”

  17. Jake1 says:

    What do we have to do to get that damn picture of Moocow Obama off this site. I get sick every time I go past it.
