It would not cause 10 foot deep volcanic ash up to 1000 miles away... 500 the most and it would be more debrees. The only main concern would be for
farmers. This is more like a flute than a trumpet..... Yellowstone is not a castastophorius grenade on land. Im not saying damage wouldn't be done,
but not like you guys make it out to be.
I recently read a scientific paper on massive world climatic changes that occurred 3000 years ago which seem to have caused civilizations to collapse
and migrate around the world. They believe the Minoan eruption may have been the cause of the climatic changes when it expelled 30-40 km3 magma into
the atmosphere. Yellowstone has the potential of expelling 2,500 km3 into the atmosphere so its effects on world food production would be disastrous.
