Where would be the safest place if Yellowstone erupts?

A: For the most likely type of volcanic eruption in Yellowstone, everywhere would be safe except in the immediate vicinity of the advancing lava flow. In the highly improbable event of a large catastrophic eruption, the great the distance from the eruptive center, the safer it would be.

Yellowstone volcano eruption simulations show an unexpected blast would produce ash fallout from the Northwest US down to the southern tip of Florida. Volcanic ash fallout of more than 39.4 inches (one metre) would blanket Yellowstone's immediate vicinity in the states of Wyoming, Montana and Utah.

The total energy released would be equivalent to an 875,000 megaton explosion. The shockwave would kill 90,000 people. Most of the lava would fall back into the crater. Any flows would be slow and only spread 40-50km or so.

No. A very large volcanic eruption would cause a severe cold period called a volcanic winter, but not an ice age. Volcanic eruptions cool the planet by creating a fine aerosol of sulfuric acid in the stratosphere. The highly reflective droplets prevent a portion of the sun's light from reaching and heating the surface.
