Generally speaking, the government is much more concerned about “keeping people calm” than it is about telling us the truth.We seem to have moved into a time of increased seismic activity all over North and South America.  In such an environment, it would not be wise to say that an eruption at Yellowstone “can’t happen”.The truth is that an eruption at Yellowstone could happen at any moment.  Let us just hope that we are all out of the way when it does.взято на просторах интернета http://www.dcclothesline.com/2014/04/01/eruption-yellowstone-supervolcano-look-like/
