But the news in the past few days has renewed concerns that the sleeping giant may be stirring. There have been over 200 earthquakes largely centered smack-dab under Yellowstone Lake since December 27. Yellowstone Lake lies on the eastern edge of a massive 35 MILE(!) by 45 MILE(!) caldera formed when the volcano erupted 640,000 years ago. That's a pretty impressive crater— so big, in fact, that it took modern satellite technology to finally recognize the formation for what it was.
This week's earthquake swarm (See this link for current mapping and statistics for each earthquake) has the National Park Service, geologists from the USGS and scientists from the Yellowstone Seismic Network on their toes, closely monitoring the situation. So far they don't seem to be overly alarmed by these unprecedented activities, although they do admit "they're certainly not normal," and "we might be seeing something precursory."
"Precursory." Now there's a disquieting choice of words.
But that's not nearly as scary as reading a Money and Business analyst from US News and World Report comment on the potential impact a supervolcano eruption would have on equity values and the labor market.
Update: 31 Dec 2008, 5 AM
I just checked the earthquake map again this morning. A 3.5 quake struck about an hour ago. I also compared the data for each earthquake and noticed the average depth of the epicenters has been 2 to 2.5 km. However, the last six quakes have been closer to the surface, around .5 km deep on average. Is that significant, I wonder? Have I made you paranoid yet?
Is President-elect Obama watching the news and shaking his head in dismay?
"Oh, that's just GREAT! We have India building up troops along
its border with Pakistan; Israelis and Palestinians lobbing bombs at each other; the for-sh** economy in a nose-dive; global warming, rampant unemployment; wars in Afghanistan and Iraq... now I have to add 'the end of life on Earth as we know it' to my list of problems? What next? A supermassive black hole created by the LHC at Cern?!"
