Yellowstone

   If the Yellow Stone super volcano actually erupted then there isn't much that we could do. We would have a advance warning because scientists and tell via the heat and pressure when the volcano is going to explode. This warning would only be a couple of days before maybe a week or two if we are lucky. The best thing to do is still before the volcano erupted we would evacuate pretty much all of western United States. We would have to set up temporary shelter for those coming from the western side of the United States. If we stay in the U.S.A. then we would probably have to use breath masks so that we wont breath in the smoke. The United States would probably fall into a state of economic depression as almost three fourths of the state is either covered in molten lava or ash.
