Scientists has researched yellowstone park for its geography, then noticed that the geography could have only be made by one thing-supervolcanoes. one thing that caught people's attention was How is the valley so big, or Whats with the obistain cliff?, all that is from volcanoes. according to research, there was 7 major explosions in yellowstone. the largest one that happened blacked out the sun for 1000 years. that explosion happened 700,000 years ago, another big explosion happened 1,400,000 years ago-. see a pattern? if so, then the explosions happen every 700,000 years. infact, the explosion is overdue. sizemonitors and sizemographs was placed in yellowstone, people discovred that is is a lava chamber THREE TIMES AS BIG AS MANHATTIAN! the volconoligist working in yellow stone sais that the chamber is big enough to make another big blast. outcome, the blast will dig a deep crater in yellowstone, and perhaps destory cities within a radius of 10 miles or more. the sulfuric acid particles will float to the metosphere, where there are no ice crystals and rain to bring it down, so it will stay up there for a long time. the fog will block out the sun, kill crops and might spread a new plauge through extreme coldness. the carbon minoxide will kill lots of people and toxins will be released into the air.
