I've been lurking in this thread for a while and it has given me much
interest and not a little amusement, but I have a question.
At risk of sticking my nose in from UK, What is the scenario regarding
the
apparently/allegedly overdue supervolcano brewing up under Yellowstone,
and
its
aftermath?
If what I've heard is correct, it might equally involve this side of the
pond.
Or is that a whole different thread? .

The assessment is that all of Yellowstone is the caldera of a
massive, still active volcano, and *IF* - which is a mighty big
'if' - it goes off at full power it will devastate most of the
western U.S. and have global consequences of horrific proportions.
However, although there are some changes taking place there -
a huge bulge developing at the bottom of Yellowstone Lake, the
ground in some areas of the park becoming so hot it can't be
walked on - there is nothing to suggest immediate danger.

A TV programme I saw over here about 2 yrs ago suggested that this had gone
off at average intervals of 100,000 years(IIRC), and was now 8 - 10
thousand years "overdue" I am not an expert, but it seems to me this is a
matter of when rather than if.
