Exactly. It's happened before, will happen again, and sounds roughly equivalent to another Krakatoa explosion. I wouldn't want to be within several hundred miles of it, when it blows. The recent 70-cm rise is disturbing, hinting at "sooner" rather than "later", from what I can recall of my vulcanolgy course (back in the early 1980's). But "Soon" in geologic terms can mean anywhere from 5 seconds from now to several thousand years from now. . . .

Not exactly. Comparing Krakatoa or even Thera to this is what a conventional 500lb bomb would be to a strategic nuclear weapon. Look at the map on the thread. HALF the US would be buried under the pyroclastic flow. This would have major global effect.

I know I know its not likely for our or the forseeable future so I am not getting my panties in a bunch, this is just presented for intellectual curiosity.

I know I know its not likely for our or the forseeable future ...

Dunno. Some experts say the eruption is overdue. And the domes under the caldera are expanding ...

The question is, HOW DEEP a pyroclastic flow ? If a big chunk is covered with a few inches, it's not as big a concern as, for instance, the flow dropped 3 feet of volcanic tuff as far as Chicago, and pretty much burying the Farm Belt under several yards of stuff. . .
