Is disaster coming soon? Some million years ago, what is now Yellowstone Park was a huge immense volcano that devastated 1/4 of the United States.

Satellite imagery, GPS stats, and a whole bunch of stuff definitely suggest that Yellowstone could very well be in trouble soon. Like the park floor has gone up 8 inches in the last few months, while the surrounding area has dropped.

As they say in the video, the question is not if it will happen, but when and how.
