250 earthquakes and counting at Yellowstone

The last full-scale eruption of the Yellowstone Supervolcano, the Lava Creek eruption, ejected approximately 240 cubic miles of rock and dust into the sky; obviously this didn't bode well for our planet causing the extinction of a great number of species.

You'll be pleased to know that 250 earthquakes have taken place at Yellowstone over the last two days, "They're certainly not normal," said Robert Smith, a professor of geophysics at the University of Utah. "We haven't had earthquakes in this energy or extent in many years."

"This is an active volcanic and tectonic area, and these are the kinds of things we have to pay attention to," Smith said. "We might be seeing something precursory."

Watch live reports of the earthquakes at the link and if we are unlucky enough to have Yelllowstone blow its top, then I bid you all farewell.

    • If you dig a little deeper they know now that Yellowstone is not the average hotspot. Its geothermal activity does not come from our core in places such as Hawaii. Instead it is from the naturally found, highly radioactive metals that surround the whole area. There is one of the worlds only platinum group based mines found about 150 miles northeast on the Stillwater river in Montana. What is really scary about Yellowstone is the high silica content in the soil. Silica produces a type of ash that has way more volume then other volcanic ash. Also a silica based lava has more elasticity which is why Yellowstone "bulges" and "swells",(Not from volcanic gas, but by the expansion of the lava). This is something it has done for 100's of thousand of years. If popped, it has the potential to cover the U.S. in at least 4 feat of ash in minutes. Also, the instability of radioactive metals give us the high chance of having little warning besides an increase of heat in the water and the ground before it "ignites" rather then "blows".
      Super scary!!!!!!!!!!!!!!!!!!!!!!!!

    • Last year I read an article about how a people on the east African coast developed arrowheads and they used them extensively.
      But for some reason, arrowhead usage did not really take hold and virtually disappeared for another 20,000 years.
      I wonder if the people who had developed the arrowhead were wiped out in one of these super-vocanoes.
      Might give us a good idea of where we'll be if one erupts again.

    • I can probably see the split right now...

      West Canada, east canada
      Western USA, Eastern USA
      West Mexico, East Mexico

      Then LAX will be it's own island like manhattan...then San Diego will probably be apart from LAX...

      then with this...the weather...and the electromagnetic fields and the solar storms...hmm...

      well i guess there is alot to think about...i think we can all survive this blast however...we will have to think more about to make food and shelter...besides...who knows what could happen.

      Honestly, they probably should seriously consider this.
      Remove the magma and use it for construction elsewhere, maybe even make some islands, or some large statue in the ocean.

      I'd rather that than the thing exploding like the last time... ;_;

      While I agree in principle, it's not practical. Don't forget what that stuff is: molten rock. Anything metal is going to warp, if not outright melt itself.

      Perhaps if it was possible to vent the gas slowly enough to prevent an eruption, maybe then.

      But honestly, if it goes, so do we, most likely. About the only ones who won't be seriously affected (other than by the ash that will be laid down globally) will be the Masai in Africa. They don't depend on agriculture. Of course, I have no idea what their cattle will eat in that super winter.

    • So, anyone else think we should build a massive container over the park filled with water?

      Not that it would hold back the force... it would be like trying to stop TNT using paper.

    • If we could get an EXACT date as to when the explosion will occur that would help me decide whether to not to send in this payment to Capital One or buy an XBOX 360.

      I'd like to get a few more games of Halo in before the extinction level event.

    • From what i was told Yellowstone is a giant batholith that was formed when a meteor or like broke the earths mantel. What i find interesting is that this happened in southeast Oregon a long long time ago. Since then the mantle or rather the crust has slid to where it now resides. If you look at a topographical map you can see the skidmark, otherwise known as the Snake River Plain, leaving a path from the corner of Oregon to present day Jellystone. As far as the earthquakes go i hope the Bison and B.F.C make it out all right, and as for those noisy polluting snowmobilers go well i will bite my fingers.

    • Don't let these figures scare you. I lived in Yellowstone for 5 years and they have hundreds of earthquakes every day. It's the most active geo-thermic area on the planet. These quakes are of a small magnitude. They're called quake "swarms". The only one that I felt in 5 years was a 4.6 and I lived less than a mile fron the fault. But, if the Yellowsonte caldera blows it's top, Israel, Russia, Iran, N. Korea and the War on Terror will take a huge backseat to that disaster. Life would change as we know it.

    • All the earthquakes seem clustered in one area. If I were to hazard a guess, I'd say a volcanoe was trying to be born or awaken.
