    The last eruption to have taken place in the Yellowstone Caldera was the Lava Creek eruption which took place over 64,000 years ago.  Scientist at the U.S. Geological Service claim that an erruption in the foreseeable future is highly unlikely.

    64,000 years ago is wrong by a factor of ten. The last Yellowstone caldera eruption was about 640,000 years ago.
