Not a big eruption at Katla (update)

Not a big eruption of Katla


mage: "This is at least not excellent refer it Kötlugos people have been waiting for," says Freysteinn Sigmundsson, jarðeðlisfræðingur. "If this is an eruption, this little event, and possibly only geothermal water," says Freysteinn and notes that sigsvæði seen in flight over the area are known to accumulate in the water itself. . Now it looks like running water escaped from the boilers. Helicopter flew over the area this morning. There were three sigsvæði and low growth in a bowl. Freysteinn say they see signs that people can now apply to both the gel and a small eruption. Furthermore, the turmoil has been changing and decreased action. The maximum gel was when it went on Múlakvísl and swept away a bridge. Since then subsided in the river and seismic tremors have diminished.

I really hope its not going off!
I've had a look at the live feed but its zero visibility

Icelands' Katla Volcano shows signs of activity

REYKJAVIK, Iceland—Scientists are monitoring Iceland's Katla volcano amid signs that a small eruption may be taking place.

The acting head of the Civil Protection Agency Iris Marelsdottir, says flooding is taking place near the volcano, caused by the melting of its ice cap.

But she says the flooding may have other causes—such as high geothermal heat—so it not yet clear whether there is an eruption.


Katla typically awakens every 80 years or


so, and last erupted in 1918.


Iceland, in the remote North Atlantic, is a volcanic hotspot. In April 2010 ash from an eruption of its Eyjafjallajokul volcano grounded flights across Europe for days, disrupting travel for 10 million people.

Katla sits beside Eyjafjallajokul.

Thank you for the link
I'm going to have a read now.

Another good source of observations and discussion on this topic:



scienceblogs.com...

Story from the BBC 2 months ago.

The story explains how they think there may be another Icelandic Volcano Eruption(s) soon.
----------------------------------------------------------------
Could another Icelandic Volcano Erupt Soon
----------------------------------------------------------------

Katla is Eyjafjallajokull's more active neighbour, and scientists believe that there may be a link between the two volcanoes.

This link has not been physically proven, explains Magnus Tumi Gudmundsson a geophysicist from the University of Iceland. A circumstantial, historical connection "is putting people's eyes on Katla," he says.

"We know of four Eyjafjallajokull eruptions in the past (dating back to AD 500) and in three out of these four cases, there has been a Katla eruption either at the same time or shortly after.

"By shortly, I mean timescales of months to a year.

"We consider that the probability of Katla erupting in the near future has increased since Eyjafjallajokull went."

----------------------------------------------------------------
Wikipedia- 2010 eruptions of Eyjafjallajokull
----------------------------------------------------------------
From the BBC source

"It seems that when


Eyjafjallajokull goes off,


Katla tends to follow."

Kathryn Goodenough from the British Geological Survey points out that, as yet, there is no physical explanation for this apparent link.

"Scientists don't yet know what the connection is," she says.

"But we know there are fissures running between the two volcanoes. And they're quite close to each other."

"They're also being subjected to the same tectonic forces.

So the chances are that if magma can find a pathway

to rise beneath one of them, it can find its way to rise beneath the other."

Researchers do know that the two volcanoes have separate magma chambers, but many suspect that these chambers are physically linked in some way, deep beneath the surface of the Earth.


"But this is only speculative," says Dr Goodenough. "We don't have geophysical evidence that makes that clear."

Flooding concern
----------------------------------------------------------------
Katla is much larger than Eyjafjallajokull, with a magma chamber about 10 times the size.


If and when it does go off, the combination of the magma and the large ice sheet covering the volcano could lead to explosive activity for a long time, says Dr Goodenough.

It is the explosive nature of the current volcanic eruption, which caused an ash plume to be sent high into the atmosphere and affect flights in the UK and Europe.

More worryingly for the people of Iceland, an eruption at Katla would probably cause major flooding. The volcano's ice sheet is 600-700m thick and all of this ice would quickly melt on to the surrounding area, which is primarily agricultural land.

But Professor Gudmundsson says there are "no signs yet" of an impending eruption. "Our eyes are not glued to Katla, we are thinking about the eruption that is happening now."

Now remember this is an article from 2 months ago so don't get the times mixed up with the current possible activity. >

Centre of screen - can anyone else see a dark blob that appears to change shape?? Some on camera glass, or something in distance?

I see the dark blob it looks like a circle sort-of..... But it appears to change shape or is spinning idk...

But it looks weird.

Maybe its just a camera effect i have no idea.

Its really hazy though can't see much right now!

Sorted my thread....keeping an eye on this one!

Thanks for the 'heads up'!

That dark colored dome is indeed a volcanic upwelling. if it's a recent developement this thing is gonna pop good.

Very bad news for Iceland then if their agriculture gets flooded . And seeing as what was said further up in the thread if it is true, of Ketla being 10x more powerful than Eyjafjallajokull then there should be A LOT of ash

Mýrdalsjökull a hazard

Update: translate.google.com...

Civil Protection have identified Mýrdalsjökull the zones, both ice sheets and glaciers, and the traffic on the glacier prohibited. Risk of hydrogen sulphide in the river near the glacier, and people are encouraged to have on the alert. . Iris Marel Daughter, in The Civil Protection Department encourages people to flee away, if it smells like is advisable to go to higher regions where people have seen or vatnselg itself.

Picture of the purported road flood and I'm not certain what all that stuff is chunks of Ice Rocks etc????

Chunks of ice from the glacier.. brought down by the floods...

still nothing on CNN.com or MSN.com about it. Of course it isn't directly affecting the US yet, so it isn't really news worthy yet.

It may still not amount to anything... small so far.. so may not make mainstream news at all.
