Hekla is starting to make unusual noises and geologists feel that an ash cloud could be on ts way, with potential to affect air travel. Hekla is near Eyjafyllajokull and is considered the mother of all Icelandic Volcanoes.

Oh no! Not again. But I'm quite sure that things will not turn as bad as 2010, again.

Geologists said last year, that an erruption of the Eyjafyllajokull would often trigger an erruption of the Hekla which is a couple of times larger than the Eyjafyllajokull. And since 1970 Hekla errupted every ten to eleven years with the last erruption happened in the year 2000.

Id like to think after that last 2, and Australia, we know more about what to expect so it does not disrupt flights as much.

Volcanos erupt in very different ways; what bothers air travel is ash, not lava. There are so many variables involved; not only what the nature of the eruption is, but what the winds are at the time. Hekla could have a much more intensive and violent eruption and bother air travel very little if the winds are favorable and the eruption is largely lava and not ash, or it could have a relatively minor eruption and it be mostly ash and bring European air travel to a halt again with unfavorable winds. All we know is that an eruption is extremely likely to happen soon; we have no clue as to what effects it will have.

This mountain is fundamentally different in that it is not a volcano under a glacier. It is likely to erupt but unlikely to produce an ash cloud of the type seen in the last two eruptions. It erupted last in 2000 and erupts regularly. It will probably be whats called a tourist eruption in that one can go close to it and view the eruption.

Eyjafyllajokull produced so much high level ash due to the melting of ice, a lot of water flowing into the hot area, producing lots of steam which rises high up, taking the ash with it. Hekla afaik currently is not covered by so much ice.

I consider such a message to be targeted to manipulate airline share rates, smells like some insider trade usual business.

The Jet Stream is way south of normal for this time of year. If it maintains its current position there won't be much of a problem.

Looks like things are a little more quiet this morning, but scientists in Iceland are urging caution.

Damn ... just returned from eight days in Iceland .. What a magical place ... Stayed overnight near Hekla in the town of Vik .. I guessed I threaded the needle between the two eruptions ... Wish I were there though ...

Exactly. I think it's time we have a system in place so people don't point fingers at who caused the other to lose money like last time. otherwise, anarchy will ensue in the New England area airports.

In recent years Hekla has errupted around every ten years, the most recent erruptions having been in 1970, 1980, 1991 and 2000. So if recent form is a guide it would be surprising if it does not errupt this or next year:

http://www.decadevolcano.net/volcanoes/iceland/hekla.htm

However I do not recall any significant disruption to European air travel at the time of any of these last four erruptions.

As others point out an ash cloud is not an automatic feature of a volcanic erruption. And as far as Hekla is concerned geophysicist Ari Gudmundsson says in the link provided by the thread opener:

“if the next eruption is of the same character [as the previous ones] it is unlikely that it will have any effects on flights in Europe”

I wouldn't worry. If you do some research you'll notice the world is having somewhat of a stomach upset. Let's hope someone's got some Pepto-Bismol. Fasten your seatbelts, we're in for a hell of a ride !!

My main concern is the mid-atlantic ridge. There's some atypical activity showing up there, it slices right through the middle of Iceland. A similar quake to Japan on that baby and it's 'sayonara' east coast and 'sayonara' any european atlantic seaboard. Like any of these matters though the clock ticks, let's just hope there's a few more ticks left.

Well, damn, we better evacuate the North American and European coasts ... Maybe the TSA could help with the logistics ... on this side of the pond, anyway ...

Never mind Hekla... the real big big one is Katla ! It is long overdue for an eruption and some Icelanders are thinking that if not this year, then definitely in 2012.

Katla has started erupting. But it is not clear how big the eruption is. A glacial flood has already occured.

The mainstream media, when it comes to science, often reflects society's propensity to confuse imagination with fact and derive scientific principles from personal opinion rather than scientific process.

Here is a blog written by an actual scientist discussing Katla.

http://bigthink.com/blogs/eruptions

He had a lot of fun with mainstream media over their Katla reporting, not least of which is using the picture of another volcano and calling it Katla.

Wouldn't be too worried here, because the European/N American plates actually move away from each other, which does not cause the huge earthquakes seen more often in the Pacific. Only the African/European plate border (running from the Azores to Gibraltar) is more likely to do this, as seen in 1755.

Biggest tsunami worry for the Atlantic is the westernmost of the Canary islands, where an underwater landslide could occur.

Cannot find any reference to this. Do you have a source?

It has been suggested that the recent media reports on this probability have grossly exagerated the likely affect of such a collapse:

I didn't read that, but wouldn't be surprised if the media indeed made it bigger than it was. We'll see it when it happens I guess...
