QT Yellowstone Caldera (the eruptions of which can be violent enough to send a layer of ash six feet deep as far away as Chicago and which erupts every 600,000 or so years and last erupted 640,000 years ago) update

Michael Alan Krajewski, an Oak Lawn, Ill., reader, writes:

“It’s been some time since we’ve seen any updates on the Yellowstone Caldera. QT has been quiet. Too quiet. . . .”
Nothing much new to report.
Just rest assured that the chance of a Yellowstone eruption larger than all the eruptions of all the volcanoes on Earth for the last 100 years put together remains only 1 in 700,000.

Which is to say it could happen at any moment..
