If it does erupt it would change the planet. But I believe there is a hot spot under the North American plate, seems like similar to the one that created the Hawaiian island chain. The plate is moving but is the hot spot moving with it? The hot spot appears to be stationary. The hotspot has been tracked back in time and geographic location through the Snake River Canyon (where there have been supervolcanic eruptions even larger than Yellowstone) all the way back to Oregon. This track coincides with the movement of the North American plate. I thought they were stationary. With the plate basically floating above the mantle that it would eventually be in another area of the plate and burst through creating another Yellowstone.

What is not stationary is the North American continent.

I had three geo classes in college, just about two more and it would have been a minor. One of the professors as I recall said it was stationary and the plate moving over it. With the Atlantic expanding and the Pacific shrinking the north American plate is moving southwest while the San Andreas fault is moving northwest.

My degree is in Geology. We are saying the same thing here.

Was the land in Northeastern Oregon still folding up into ridges at the time that the caldera was located there?
