According to National Geographic, the researchers, from Arizona State University, analyzed minerals in fossilized ash from the most recent mega-eruption and found changes in temperature and composition that had only taken a few decades. Until now, the magazine reported, geologists had thought it would take centuries for the supervolcano to make the transition.
The discovery, which was presented at a recent volcanology conference, comes on top of a 2011 study that found that ground above the magma reservoir in Yellowstone had bulged by about 10 inches in seven years.
"It's an extraordinary uplift, because it covers such a large area and the rates are so high," the University of Utah's Bob Smith, an expert in Yellowstone volcanism, told the magazine at the time.

I agree with Stephen Colbert's take on this story: "I dont know about you, but after this week, Im ready."

(51,129 posts)I grew up playing on one of the ash layers turned to stone. I've visited the series of eruptive locations that have moved over that hotspot for many millions of years.
Why do you assume others are ignorant?

(30,613 posts)That can genuinely be debated; it's probably about as predictable as earthquakes in California. In other words, bad ones will happen; we just can't say when with any accuracy at all.

(51,129 posts)If a super volcano could wipe out life on earth, there wouldn't be life on earth because there are lots of super volcanoes. They go off very frequently in terms of the timeline of life on earth.

(34,136 posts)Basically it says that there would be less warning time than previously thought before a Yellowstone eruption, as if any amount of warning time would be used effectively for such a massively catastrophic event - politicians would argue and ignore the scientists, leaving the people closest to the danger zone in limbo until too late to act.

(544 posts)Homo Erectus was around over a million years ago. Obviously it didn't wipe them (or the rest of life on the planet) out... because we're still here as well as many diverse species. They were considerably less advanced than we are with considerably less technology and accommodation to survive such a catastrophic event. There would a drastic reduction in the amount of people... but overall I have no doubt that Homo Sapiens (us) would prevail on a much better basis than did our ancestors.
I think a global event of this magnitude might cause some of the more unhinged military superpowers to "take advantage" of global civil disorder... launching nukes and things like that.

Excerpt:
"But a Yellowstone megablast would not wipe out life on Earth. There were no extinctions after its last three enormous eruptions, nor have other supereruptions triggered extinctions in the last few million years. [Wipeout: History's 7 Most Mysterious Extinctions]
"Are we all going to die if Yellowstone erupts? Almost certainly the answer is no," said Jamie Farrell, a Yellowstone expert and assistant research professor at the University of Utah. "There have been quite a few supereruptions in the past couple million years, and we're still around."
