I remember we have previously had a few discussions here on the forums in some other threads regarding the volcanic activity, etc., at Yellowstone National Park in the USA. Always an interesting subject and now there has been a new discovery at Yellowstone of another big magma chamber:

I never thought much about Yellowstone until seeing a program on television one time talking about the volcano there and that if it ever did explode that it would destroy a great part of the United States. Whether that may ever happen or not remains to be seen but ever since seeing that program I pay more attention to any news I hear or see regarding Yellowstone's volcanic activity, etc.
