Due to the recent news articles about increased activity at Mount Saint Helens, I was searching on other North American volcanoes and areas with possibility of volcanic activity.
In some of these places I find links mentioning the “Yellowstone Super Volcano,” harbringer of the end of human life within 600 miles of the eruption.
I realize there is significant activity underneath Yellowstone, but what is the actual probability that a super volcanon could erupt/explode in the near future? Some of the sites in my search result seemed like much ado about nothing (just Google Yellowstone Super Volcano to find the links- I won’t list them here).
Thoughts?
Not a link to a web site but “A Short History of Nearly Everything” by Bill Bryson has a chapter on this. My typing is too slow to give much of the details but he says that the eruptions occur approximately every 600,00 years and the last big one was 630,00 years ago.

“It is important that everyone understand that current geologic activity at Yellowstone has remained relatively constant since earth scientists first started monitoring some 30 years ago. Prospects of renewed volcanism are still far away. Although another caldera-forming eruption is theoretically possible, it is very unlikely to occur in the next thousand or even 10,000 years. Smaller eruptions are more likely, but even so, we see no signals of any impending volcanic unrest. YVO maintains an array of instruments that monitor activities at Yellowstone around the clock.”
