I know there is a whole post on yellowstone and probally more scientific than this it's just what i remeber from geology classes and notes i have
taken.
If i remeber correctly, yellowstone has erupted 3 times each erruption coming from a different caldera. So in fact it was three seperate
volcanoes.(everything is approximated and estimated also for comparison Mt. St. Helens released about 1/3 square mile)
1st time: 1.8 m.y.a (million years ago) 200 sq miles of new material was released (1200 times Mt. St. Helens eruption)(I believe it was this erruption
my professor refer to when he mentioned it was enough to dump a foot of ash in detroit)
2nd time: 1.2 m.y.a 120 sq. miles of new material released
3rd time: .6 m.y.a 63 sq miles of new material released
Personally, I would expect the next erruption to produce about 20-30 sq miles. Still a lot of damage but no where near the extent that people make it
out to be. That said it is also possible to be much larger. The worst part of the volcano is the fact that it sits just to the west of the plains and
one of the largest crop producing areas in the world. Also the runnoff could bog down many riverways including the mississippi.
Also of note that time frames have a +/- of 50,000 years and the fact that some of the material has to be dated using the "whole rock method" with
the exception of some rocks that are partially crystallized doesn't give as accurate of a reading so the time range can be off by more than the
50,000 years.
Also of note is that some people who use "biblical" refrences for the end of the world use a comet or asteroid along with yellowstone. (one source i
have seen people use on this site is www.onealclan.com but personally i have found that they have several misguided statements).
There is some evidence that supports the theory that an impact of a size large enough to cause such significant damage such as the extinction of the
dinsaurs also would cause a massive flood basalt flow on the oppisite side of the earth. (There is a massive flood basalt that is opposite the yucatan
pennisula that is dated to the same time period as the yucatan crater which is generaly accepeted as the most likely spot for the impact that killed
the dinosaurs.)
Like i said these are all from notes I took during my geology classes. The numbers for yellowstone may be off some. I'm not a geologist just have a
hobby and interest with it.
One last thing, I personally don't believe in parts of the bible, such as revaltion. I just added in the parts about a relation with some theories
and yellowstone because that's what you were asking in the first place.
