Yellowstone- from W. G. Sweet

Yellowstone

W. G. Sweet “The Yellowstone caldera is going to erupt sometime in the next few days. Not a maybe, not an educated guess: It has already started. We have had a few small quakes, but the big stuff is on the way.”

“Super volcanoes… Earthquakes that modern civilization has never seen… The last super eruption was responsible for killing off the human population some seventy-four thousand years ago: Reduced it to a few thousand. And that is not the biggest one we have evidence of.” He paused in the silence. https://books.apple.com/us/book/yellowstone/id1441067513
