I hope the British Government is chartering some cattle boats to get the football hooligans (and that's just the players) back from RSA next week if it does kick off

The data from the earthquake monitors is pretty useless if we don't know how to analyse it. The tremor levels are very low, especially those closest to the Katla volcano. If you go and look at earthquake maps of other places in Iceland you'll see that minor quakes happen there all the time. Actually, the volcanic eruption probably obscured a lot of these quakes in the background tremor. What's more, these recent earthquakes around Katla have high error factors on them and are at very shallow depth. The Icelandics don't seem too concerned!

Yes, these quakes are very small as compared with those occurring around the Pacific Rim on a daily basis but Katla tends to blow without warning, these small tremors are the only indicator we have. What worries me is that the quakes are so near the surface, indicative of something imminent.
I look forward to hearing Wright Turbo-Cyclones and Bristol Centaurus engines droning overhead.

Beautiful imagery - but still fails to address the key problem: timeliness. I assume at least some of the satellites in use were in polar orbits, so there's a variable delay before the patch of atmosphere you want gets imaged. Geostationary sats are (maybe...) too far out to deliver the detail needed and anyway don't carry the relevant sensors. (I may be entirely wrong on this.)
Icelandic conference
Apparently there is a conference in Keflavik next week with an assembly of assorted experts to consider the lessons of the great volcanic ash drama - and presumably to suggest future measures. Anybody going - or have any idea which way the wind might blow (sorry!) there?

Or maybe not.
Have they invited anybody with a view other than their own one ?

EUMETSAT IPPS animation - Meteosat 0 degree Ash Iceland
Our geo satellites contain all the sensors needed for ash analysis. Although, as always, additional sensors would be an improvement (which will arrive in 2015).
On the plus side, because iceland is near the poles we gain a lot of high resolution polar data at high frequency - we can gain 5-6 images of iceland per day from polar sensors.
(edit) Oh, just noticed that the post was a month old. Apologies.

Before getting the Connies out in the air(*) I have been told that a US airline is suing an hollywood production firm for over a billion US$ for loss of revenue because this firm had placed high explosive charges near Eyjafjallajokull to start an eruption for film footage (for a mega production to come) a few days before the full eruption.
Could not find any confirmation of this on the web. Anyone heard something or is it just a wild story ?
(*) restauring a Connie to full flying status is extremely expensive and a very lenghty process as the Lufthansa staff in Berlin can tell you :They try since 2 years to get one in the air from 2 "good" airframes,but they are still years away .

Really? I doubt it though, if it did it would have to be a hell of a lot of 1.1 high explosives buried deep within the volcano a rather expensive do, surface explosions the gases are released upwards, with very little effect downwards.

SIA cancels Jakarta flights
Well Merapi has only be chuffing away for 12 days and QF has had two engines fail on climb out of Singapore so I guess a little respect for mother nature is probably overdue.
If ash forms a hard glaze on the hotsurfaces then I suppose the risk of blades being heavier than designed might stress an engine if the glaze is not dealt with.

False Alarm. Iceland Met Says No Imminent Threat of Eruption
A story has been making the rounds in the British press and elsewhere that an eruption is imminent in Bárdarbunga in Vatnajökull. The news seems to be based on a misunderstanding of a TV interview with a specialist at the Icelandic Met Office earlier this week.

Didn't I read somewhere, once upon a time, that there are
constant volcanic eruptions occuring all round the World?
Minor ones, admittedly, but most pumping loads of crap into
the atmosphere.
