Yellowstone's overdue...
If that goes, wouldn't it bring about the end of civilisation.....?

That's "when" and quite possibly.

Aye, imaging what it was like when Krakatoa went pop, that wee one was a tidler.
I don't quite understand how it can build up such explosive power to create a shockwave like that, it really must be like champagne bottle under the ground.

You've had a curry with plenty of beers, right? wink

It's more comprehending how it becomes so explosive, I see the eruption as easy to understand but the forces being created is just very hard to comprehend, particularly when you see that video above and you see the sort of sonic boom effect. It's not from things combusting from what I understand, more the sheer force of material moving?

Imaging the curry but you have accidentally sat on a cork and it will not budge. For a while.

Its like this, they were experimenting with laxatives in a French Lab. Feeding it to a pig with barrel loads of swill. They shoved a cork up to control the release and measure the amount to see how effective the laxative was. To pull the cork the out they trained a monkey, this was the only task the monkey had ever been trained for. Anyway, they were feeding the pig but forgot to give the command to the monkey to pull the cork, the junior scientist on duty that day belatedly gave the command.....


When the clean up team eventually made it to the lab, clearing the way through all the pig waste, they found the junior scientist in hysterics. They wondered at this as he had spent days submerged in the stuff. They asked if he was laughing at the mess. No he relied, it was the monkey trying to put the cork back in.

Most insightful!

Latest news said:
Three scenarios are still considered most likely:

- Subsidence of the Bárðarbunga caldera stops and the eruption on Holuhraun declines gradually.
- Large-scale subsidence of the caldera occurs, prolonging or strengthening the eruption on Holuhraun. In this situation, it is likely that the eruptive fissure would lengthen southwards under Dyngjujökull, resulting in a jökulhlaup and an ash-producing eruption. It is also possible that eruptive fissures could develop in another location under the glacier.
- Large-scale subsidence of the caldera occurs, causing an eruption at the edge of the caldera. Such an eruption would melt large quantities of ice, leading to a major jökulhlaup.

Other scenarios cannot be excluded.

A "jökulhlaup" is a catastrophic, sudden, flood. http://en.wikipedia.org/wiki/J%C3%B6kulhlaup

Few years ago that happened, not the last spat. Washed away a valley or something, made the main news.

There's recently been a M4.8 and a M4.1 in the volcano itself, that's on top of this morning's M5.5

Busy times...

Back on topic.

Noticed an interesting effect with the web browser and web cam. I have the web cams open in their own tabs, then surf in other tabs. Wander out for a bike ride or potter around the garage and come back for a look see in those tabs and I get a speeded up run from when I last looked to the time that I open the tabs again, its like fast forwarding the last hour in a few seconds. Which I could record it.

The latest info

http://www.dailykos.com/story/2014/09/10/1328836/-...

Extremely high peak readings of SO2, and an increase in frequency of large quakes in and around the caldera. Iceland appears to be ramping up its emergency plans etc.

Wow, so quite a bit of material has already been dumped and its own little mountain has grown from it. Logical when you think about it, but still an amazing act of nature!

These pics are, of course, just the fissure. I hope some cameras are still pointing at Bardarbunga for the main event.

Getting increasingly nervous about being trapped in Boston next week!
