Yes, at some point it probably will, it is far from dormant.
Part of it’s attraction is that it is very much active.
Eventualy, when the pressures and heat build up enough.

When will it do this?

I dont think anyone knows exactly.
In geologic terms an error of +/- 500 years is a blink of an eye.
And not everything in the earth works by an atomic clock.
Though old faithful may wear a timex, the magma pit under it most likely isnt quite that precise.

No human has ever recorded the events of a super volcanoe, so there isnt any first hand knowledge to go by.
If people are around when it occurs again, they may or may not realize what is going on.
It may not even give the kind of warning signs we are looking for exactly.

But even if the scientists felt very strongly that it was about to blow, i dont think they would tell people anything simply because it would be pointless.
It would be like looking into space and finding a moon sized asteroid on an absolute collision path with the earth.

You can’t run from it, you can’t stop it.
There is no point in making everyone else worry about it.
That serves no purpose, and is cruel if nothing else.

To the person collecting gaskmasks and canned food.
Gas masks are of no use, if i put you in a box of hydrogen and sulfur gas, and give you a gas mask, what are you going to breath?
They dont create oxygen.

There isn’t any place to go running to, nor doubtfuly the time to run to begin with.
The last time the yellowstone cauldera errupted, it was global.
It is not like Mt St Helens, it is unimaginably much much bigger
If your in montana, you wont ever know it even happened.
I’m sure you can read up on the approximate sequence of events before, during, and after a super erruption of that magnitude

Things like this are beyond human beings worrying about.
Something will kill the planet at some time, and we can not do anything at all to prevent it even though we have aquired the need to control every occurence in the universe.

Someday the sun will super nova, and incinerate everything.
Someday a supercauldera will errupt causing a variety of things to happen.
Someday a large body from space will impact the earth again.

The only thing worth worrying about is that we dont kill the planet ourselves before then, and that you live your life and handle the way you treat others as if each day was the only day you had to live.
