I'm caught up in the blog family spirit after reading the recent round of posts. So in that spirit, I will 1) quit blagging, and 2) resume my role as resident pessimist.
Most of y'all are science nuts, so you may have heard about the recent earthquakes in Yellowstone. If you haven't, well, it's probably better. All those neat geysers and hot springs are geothermal, of course. And geothermal means heat. And heat means magma. And magma, when it blows out in a big way, means calderas. Yellowstone caldera was formed from a volcanic eruption and is roughly 34 x 45 miles. That's a heap 'o magma. When you see that much, you're going to have a very bad day. Don't trust me on this, trust the Discovery Channel:
the Yellowstone eruption of 2.1 million years ago, which is described on the VEI as an eight: mega-colossal, with a towering ash cloud 10 miles high that pours out at least a thousand cubic miles of ash. That Yellowstone eruption had 10 times the ejected material as a VEI 7 volcano, which modern humans have never seen either.In fact, the last VEI 7 eruption was in Toba, Indonesia, 74,000 years ago, and it caused such global cooling that some scientists think it nearly drove humans to extinction.
On the other hand, it might just be some water moving around, or a little seismic hiccup, and some other poor schmucks will have to endure global extinction. Happy news for us! I can take a drink, and we can go on with planning game night.
