@ ^ See :

on youtube for that docudrama in six parts apparently & see :

http://en.wikipedia.org/wiki/Supervolcano_(film)

for the wikipage on it. WARNING – SPOILERS there.

This youtube clip :

is excellent albeit too &, I think, accompanies that series albeit it’s an hour long. Worth watching though I reckon.

@ ^ Wzrd1 : Thanks. Glad you liked that bit of doggrel.

As for Yellowstone being dormant, I’m not so sure. There’s still a lot of geothermal activity as shown by the geysers there like Old Faithful. Wikipedia – click on my name for link – notes :

Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone Caldera since the last supereruption. The most recent lava flow occurred about 70,000 years ago, while the largest violent eruption excavated the West Thumb of Lake Yellowstone around 150,000 years ago. Smaller steam explosions occur as well – an explosion 13,800 years ago left a 5 kilometer diameter crater at Mary Bay on the edge of Yellowstone Lake.
- Wikipedia -Yellowstone hotspot page linked to my name here.

Suggests it could be expiring but there’s still, I think, some uncertainty about this. Aussie ABC TV showed a great fictional doco -drama ‘Supervolcano’ a few years ago about a hypothetical present day eruption of the Yellowstone supervolcano.

PS. How did you get that last emoticon there? Didn’t know you could have that one here.

@Nina F, the last time I checked, Yellowstone qualifies as dormant. Or have we now requalified dormant as being millions of years without eruption, rather than thousands of years (where Yellowstone has been dormant for 70000 years)?
If the latter is true, the Earth has MILLIONS of volcanoes. Which is NOT reflected in current geological texts.

@Messier Tidy Upper, LOVE the work! I only manage such creative prose during very long drives…
Probably because only then am I uninterrupted…

Verdant volcano in a silvery sea
Please don’t, please don’t, erupt on me!
Tinakula volcano, nice & small
Glad a supervolcano, you’re not at all!

Great image.

You’ve never been to Yellowstone National Park, and stood within one of the world’s largest active volcanoes?
Just because it’s not one of those obvious strato or shield volcanoes, Don’t dis it!
Visit Yellowstone before it visits you!

“I’ve stood on a few (though never an active one — but that’ll happen someday!)”

Step 1: Stay where you are.

Step 2: Wait.

Sincerely,
Your Friend the Plume
