There is a mantle plume underneath Yellowstone's plate boundary, which explains it's activity.  There has also been a slab that was found, and that- taken into consideration with the plume creates problems.  The slab is becoming weak because of the plume, and this is what helps to understand the activity of volcanoes in the area.  More research is always happening...

The development of "Eurasia" is mostly due to the combining of plates between Europe and Asia.  Large experiments were conducted, and followed the progress of the two plates colliding.  As research is being done, they are hoping to prevent further more activity in the area.  If there is more activity with the collision, millions of people may be at risk.
