Hey, to tell scareying supervolcano stories, don't forget, there are at least two other active volcanic centers in the lower 48 states that have spawned super volcanic eruptions in roughly the same time frame as Yellowstone. One of them, the mono-inyo field in eastern California, next to the long valley super volcano that erupted 760,000 years ago, has been ranked by the USGS as more likely to stage a major eruption than anything in Yellowstone, and is located much closer to major cities in California. Why are you not panicking over that one?
Just to scare you more, there is more than just lots of earthquakes in the mono-into field, but the whole chain of lava domes that pushed up in the last 40,000 years there appear to trace out a gigantic circular ring fault, reminiscent of the development of a major new caldera and mirroring what the development that preceded the long valley super volcano eruption there 760,000 years ago.
When long valley caldera erupted 760,000 years ago, it shot a pyroclastic flow westwards towards San Francisco at such high speed the flow climbed over the top of the Ridge of the 11,000 foot high Sierra Nevada mountains, and flowed down the west side of the mountains filling the preexisting valley of San Joaquin river into the Central Valley about 80 miles away.
