Is Kull Just An Hors D'Oeuvre?

Paul McAuley meditates on the plumes of smoke:

Eyjafjallajökull may have created all kinds of disruption to travellers, but compared to supervulcanism of the past, or to what might happen if the volcanic dome under Yellowstone Park lets go, it’s a mere blip. An inconvenience rather than a catastrophe. A useful reminder that the nemesis which may clobber us won’t necessarily be the product of our own hubris.

Incredible photos of the volcano in action here and here.
