What damage would be done if Yellowstone National Park Erupted, How far would the cloud travel. And what radius would it effect etc etc etc?

Presently, Yellow Stone Park erupts every day and every hour.    It has many
guizers  scattered all over the park.    These guizers act  like small guizers.
But instead of spirting off fire, smoke and lava, these guizers spirt out hot water and steam into the air.    They are beautiful to look at while doing so.
How do I know?  I was recently there.                                      Seesee
