A scientist is warning that a volcano in Yellowstone National Park in Wyoming could one day erupt-- and it would literally tear the guts out of the US.

He says there’s been three major Yellowstone eruptions in the past… around 0.6 million, 1.3 million and 2.1-million-years ago.

Each of these super-eruptions were large enough to spew monstrous amounts of volcanic material and ash across the US.

But he says the good news is, there are no current indicators Yellowstone is ready to blow up anytime soon.... and it likely won’t happen in our lifetime.
