“What Is Happening Under Yellowstone Park in 2017?”, from News USA 2017, plays on the recent reports of earthquakes in Yellowstone National Park as a possible precursor to a massive eruption.
The video mentions the rumor that the US has contact four countries to ask for radical hospitality to house US homeowners made homeless by the eruption. A map in the video shows the predicted zones of destruction, which would encompass about one third of continental United States. There are reports that there is a 10% chance of a massive eruption by 2100. Eruption occurs about every 650000 years, but we are about due (but statistically any given year is unlikely).
The video then goes on to speculate about a secret network of underground bases all over most of the US, with many subterranean high speed lines already bit. It even speculates these bases could explain some UFO abductions.
