I don't know. I find it humbling. Nature, our quiet ruler. |
Not most of the us, just the Yellowstone region. But the effects of such eruption would affect all of the continent and rest of the world for decades.
On the plus side it erupts every 600-700 mln years and the last one was app 600 mln years ago, but some think the plume is weakening. The magma chamber is there all right and usgs monitoring reports on it 24/7.
There was a great BBC series a few years ago about a Yellowstone blowing up, recommended.
Plume volcanoes are called supervolcanoes, their sizes are enormous. They're dotted around the world. The most worrying atm is the one in Italy, campi flaegrei.
