Apparently a volcano which erupted at Yellowstone National Park (about 650,000 years ago) could still be active.

Bill McGuire, professor of geohazards at the Benfield Greig Hazard Research Centre at the University College of London says it could bring, "the bitter cold of volcanic winter to planet Earth. Mankind may become extinct."

(Make every minute count, people.)

    • That was a brilliant film. Very tense. My wife, sons and I just moved back to London after almost six years in the States. I think we made the correct decision. I think I must buy an extra freezer and fill it up with provisions. Must also take Mayor Bloomberg's advice and buy loads and loads of canned goods and wind up lights.

      Spooky.

      Anyway, here's a wee film needing votes that might cheer people up...

    • You betcha.

      Beneath Yellowstone is a vast caldera covering 1,500 square miles. Check a map. It is the size of Lake Michigan, or the Irish Sea.

      The temperature of its molten rock was measured at 1652 degrees farenheit.

      It is expected to erupt every 600,000-700,000 years. The last cataclysmic eruption was 630,000 years ago.

      Since 1988 magma pressure has forced hundreds of square miles of land to rise by 3 feet.

      Combined with the San Andreas Fault, and another once-again active super volcano (with an underlying caldera of 212 square miles) in Long Valley California, the Western USA literally is Dancing On The Dragon's Jaw.

      When the Long Valley site last erupted its pyroclastic flow added 350 feet of surface height over several hundred square miles.

      The power of nature. We underestimate it, constantly.
