Yellowstone is stirring once again...
In my November 28th column "5 Things to do with $10 Billion a Month," I mentioned the megavolcanic eruption of 70,000 years ago as a challenge our species has faced -- and surmounted. That ancient catastrophe bottlenecked the human population and reduced our numbers to a few thousand or less.
Last week in my column "Resolution for a New American Year," I mentioned the Yellowstone megavolcano as something we should be paying attention to. Yellowstone is, like the ancient eruption which threatened us, a simmering cauldron of nature's fury pressure-cooking beneath the famous national park.
Well, yesterday came word that 400 small earthquakes have begun rocking Yellowstone for the past few days, and it's got scientists worried.
Says Robert Smith, geophysics professor at the University of Utah:
"[The earthquakes are] certainly not normal. We haven't had earthquakes in this energy or extent in many years."
