There is a massive volcano in Yellowstone National Park that is worrying some scientists while others say it is safe. Earthquakes deep below are common, as are escaping gases. What is causing some alarm is the release of Helium-4 a rare element released from very old rocks. Some see this as a sign that an eruption could happen in the near future. It would wipe out everything in a 500 mile radius and cover two thirds of the USA in ash if it erupts.
