Yellowstone supervolcano stirs in its sleep

The gigantic volcano seething under Yellowstone National Park could be ready to erupt with the force of a thousand Mt. St. Helenses! Large parts of the U.S. could be buried under ash and toxic gas!

Or, y'know, not.

This story has popped up in a couple of places recently, including National Geographic's website and, more sensationally, the UK's Daily Mail. Shifts in the floor of Yellowstone's caldera indicate that magma may be pooling below the surface, a phenomenon that might be the very earliest stages of an eruption. Then again, it's difficult to predict volcanic eruptions with much accuracy because there's no good way to take measurements of phenomena happening so far below the earth's surface.

Incidentally, the contrast in tone between the two stories makes them an interesting case study in science reporting: The Daily Mail plays up the possible risk and horrific consequences of an eruption, while National Geographic is much more matter-of-fact about the remoteness of that possibility. Which do you think makes better reading?
