If it blows, everyone needs to back up at least half the continent.
As the links above show, the Yellowstone CALDERA is a SUPERVOLCANO and if it blows, the best bet will be to BE ON MARS.
No, like most of the clueless hypemongers that totally misunderstand this story, you fail to understand that there's a vast difference between the underwater lake dome exploding, and the caldera exploding, and have confused the two.
Calderas have a WIDE VARIETY of eruption modes. For every time an entire caldera explodes, there will be hundreds or thousands of small cinder cone eruptions, bursts in geyser activity, phreatic explosions, lava flows, etc. over tens of thousands of years.
The bulge in the lake exploding IS NOT THE ENTIRE CALDERA exploding.
If the bulge in the lake explodes it's no danger to anyone that isn't in the park near the lake. And it won't trigger the caldera exploding or really be any sort of sign the caldera might explode.
And caldera explosions are so rare on the grand scheme of geological things to worry about in the US it's very low on the list....a collapse of Mt. Rainer, the Hayward fault going in Oakland and Berkeley, a hidden thrust fault in LA going, New Madrid...those are all things that realistically could happen in someone's lifetime.
Why? Just because the møøselimbs will see it as a sign from their pig god?
(Isn't Krakatoa how so much of Indonesia ended up møøselimb?)
