Anybody else watch this last night/tonight?

OK, the basic premise is extremely unlikely, at least any time in the next 100,000 years, but I thought it was pretty well done.

For those in the US, it's a BBC/Discovery (amongst others) co-production, so I guess you'll get to see it over there some time in the next few months.

Yep, watched it last night, haven't seen it tonight though. Yet  Wink

Could happen anytime... scary thought really! But yeah, the programme is really good, and the documentary after on BBC2 was interesting too. And there's another tonight. Can't wait  Smile

Well, yes, I suppose. Though as they said in the documentary, there are no indications that anything is imminent, and to be honest, it's not like there's anything we can do about it anyway. Not worth worrying about.

Yep. I'll be watching the concluding part tonight. Volcanoes, are highly unpredictable as we know. BBC2 featured the actual facts about this Supervolcano that lies underneath Yellowstone National Park.
How big is the lake of magma that lies there? MASSIVE!!  Wow!.
The vulcanologists admit that it is a ticking bomb but I think while ever "Old Faithful" and all the other geysers keep letting off the steam, its relieving the pressure. If it ever goes quiet then it signals BIG trouble. Its the same with a pressure cooker. It has a release valve for a reason.
Its the volcanoes and major fault lines that haven't been active for years that are the big worry. You only have to look at Mount St Helens for evidence.After a couple of hundred years , it finally blew its top after remaining inactive for so long.
I first knew of this Supervolcano in the US after reading about it in a magazine.The sheer size of it was unbelievable.
Our planet is amazing, but if ever this big baby does blow, I pray it does it when I'm long gone. The fallout effects would trigger major climate changes and the possibility of many lifeforms being totally eradicated including ourselves. Never under estimate the hidden power of our planet from 25 miles down under our feet. Evidence of past super eruptions are there and scientists have got it wrong before.
Lesson to be learnt? NEVER take nature for granted.

Sorry to disturb you, but geirirsare not relieving any pressure. They happen when rainwater runs down cracks into hot rocks, evaporates and when the steam pressure becomes more than the weight of the water column above it, it will blow everything out.

There is a major hot spot about 50 km from where I live under the Eifel hill range, lasttime it has been active (vulcanic eruptions) was about 10.000 years ago, no time by the geological time scale.
You also have hot spots in Britain, AFAIK there is one right beneath Edinburgh (Why not Glasgow?  Wink )

I believe the one is Scotland is dormant.

The trouble with programmes like these, is that the Human Race generally cannot think in geological time, we are almost programmed to think in recorded history or human lifespan terms.

A supervolcano eruption in the Far East, 70,000 years ago, affected climate so much that the Human Race at one point down to a few thousand, as our DNA shows.

Same with space debris, large asteroid and comet strikes are very rare, but smaller ones, enough to destroy a city, are more common, only in the past 100 years the human population and urbanisation has exploded, so unlike Siberia in 1908, or the rock thought to have hit the Saudi Empty Quarter in the 1930's, the chances of one causing massive loss of human life are increasing.

And yes, I enjoyed the programme.

They had the scientific advisor to the programme on Radio FiveLive this afternoon, and he was quite pleased with the result (as well he might be I suppose) and one point he did make was that a tsunami on the scale we saw in the far east a few months back is, geologically speaking a pretty rare event as well. He said that had a programme like this been made a couple of years back then the same criticisms could be made, but that these things do happen, albeit very, very rarely.

Oh, and I think the volcano under Edinburgh Castle, is, I believe, extinct, not dormant. Had it been under the Holyrood Parliament I suspect there would be a few volunteers to dig down and try to re-activate it.  Wink

I can hardly wait for the Yellowstone supervolcano to blow! That'll level everything within a thousand miles.  bouncy

I only saw a bit of it during the commercial breaks of Most Haunted!

Shame as it looked like a well-researched and interesting programme. For a Monday the telly was really good tonight (Clockwork Orange as well!)
