The Tambora Volcano back in 1815 (the year without summer - well, 1916) had 12 cubic miles of ash. The largest event at Yellowstone was 525 cubic miles of ash. WOW!
In one article describing it the writer was saying how WHEN Yellowstone erupts, lots of people from the US will be lined up at the Mexican border. (They can ALWAYS find a way to plug there Liberal crap - can’t they!?)
I’m not sure how certain it is that it WILL erupt. I would guess it would, but I’m not sure it is like active fault zones that we know will slip again some day.

The ashfalls from the previous three eruptions only crossed the Mississippi once and then got as far as Mississippi and Ohio.
