I've seen this other places than the Daily Mirror so I know this is a real alert- I've had a sort of low pressure headache that I sometimes get before earthquakes for several days now. It can be ignored, sometimes it is allergies but it tends to life after an earthquake happens - it has not lifted with these quakes, which makes me wonder if an eruption may be brewing (or there is just too much ragweed blooming outside)...

Iceland volcano comes closer to eruption after experts record intense seismic activity at site

Bardarbunga is bigger than the Eyjafjallajokull volcano which caused travel chaos in 2010

Experts are on high alert after a huge volcano came a step closer to erupting.

The risk of an eruption on Bardarbunga, which is Iceland's biggest volcano, has been moved up to level four - the second highest grade on the scale after officials recorded intense seismic activity at site.

In 2010, a giant ash cloud caused travel chaos, when Eyjafjallajokull volcano violently erupted.

Huge stretches of European airspace were shut - ruining the travel plans of over 10million passengers.

Officials warned there are strong indications of magma movement in the volcano, although there have been no indications that it could erupt.

Met Office seismologist Mr Martin Hensch said an ash cloud similar to the one in 2010 would depend on the size of the eruption.

He told RTE: "Presently there are no signs of eruption, but it cannot be excluded that the current activity will result in an explosive glacial eruption, leading to an outburst flood and ash emission."

Checked in with family in the Reykjavik area today. So far so good. No earthquakes being felt over there. Will try to get updates if this thing goes hot.

Thanks IRoberge - I gather the quakes are not that large, but are constant and shaking the area of the volcano itself (per other articles I found on this) - one article said there was a danger to some of the power plants and a lot of issues that might occur with air travel etc; but I don't think Reykjavik itself is in any direct danger.

Thanks Melodi! Here is some more on Iceland activity.

Alert level increased to ORANGE for Bardarbunga volcano , Iceland ? (update 18/08 at 13:34 UTC)
Still no eruption, but lets call it that the eruption is imminent and could happen anytime. An eruption does NOT mean a free air eruption as most of the Barbardunga activity kept nicely below the upper part of the glacier (also called subglacial). Some collapsing parts of glacier on top of the the activity location is also possible, just like it happened in 2004 with the eruption of the Grimsvotn volcano. The picture below shows what’s happening then – an ice river who might create a jokulhlaup which could lead to Ice rivers with an increased flow and big ice chuncks. These jokulhlaup‘s are the reason that some roads below the glacier complex have been closed

Intense seismic activity in Iceland’s Bárdarbunga volcano


Seismic activity in Bárðarbunga, a large sub-glacial volcano in Iceland, has increased. A seismic swarm has been ongoing since 3AM this morning, and near continuous earthquakes have been occurring ever since.

The depths of earthquakes in the present swarm are in the upper crust and their magnitudes are mainly around 1.5; a few earthquakes are of magnitude greater than ML3. According to geologists, there are no signs of magma moving to the surface presently. The seismic activity abruptly started on August 16th and is still ongoing.

According to the Icelandic Met Office, an earthquake of magnitude 3.8 occurred at 02:37:19 this morning (18th August) about 2.4 KM NNE of Kistufell in northwestern part of Vatnajökull. Reports are indicating that it was felt in Akureyri, N-Iceland. This is the most intense earthquake swarm in this area for years; measurements also indicate magma movement.

Prediction: August 28 eruption.

If correct, Panic Sex Lady will reveal her secret volcano formula...

I was reading about this yesterday and yes they are a little worried about what it will do locally and keeping an eye on this one. They have noted that the land or ice mass on one side is rising a sure sign of magma activity. If this were to blow by the end of the month with a great deal of force and ash it will have an affect on this coming winter.

Now on Bloomberg via Drudge:
Iceland Tells Airlines Volcano Under Glacier May Erupt

A cloud of smoke and ash is seen over the Grimsvotn volcano on Iceland, on May 21, 2011.

Iceland warned airlines that there may be an eruption at one of the island’s largest volcanoes located underneath Vatnajokull, Europe’s biggest glacier.

The alert level at Bardarbunga was raised to “orange,” indicating “heightened or escalating unrest with increased potential of eruption,” the Reykjavik-based Met Office said in a statement on its website. Over 250 tremors have been measured in the area since midnight. The agency said there are still no visible indications of an eruption.

The volcano is 25 kilometers (15.5 miles) wide and rises about 1,900 meters above sea level. Bardarbunga, which last erupted in 1996, can spew both ash and molten lava.

Ash from Iceland’s Grimsvotn volcano forced flight cancellations in Scotland, northern England and Germany in May 2011. An eruption of the Eyjafjallajokull volcano in April 2010 caused the cancellation of more than 100,000 flights on concern glass-like particles formed from lava might melt in aircraft engines and clog turbines.

Ok, to keep anyone interested in this up to date I found this and it's a little more than I care to type out and its text with a good deal of charts and a long read. The data/info all the way at the bottom starts off at August 15, 2014. and go from there to August 21 of 2014. This looks like its done by some who works with Iceland's Department of Geology and his name is Jon Frimann.

Interesting link there Publius, he says that it appears the caldera there is lowering which would explain the quakes and that these sorts of events would tend to be huge. O.o

Two things about the caldera when the ice hits magma, big, big, explosion. Secondly, expected large flood, when molten lava starts melting ice. Bad situation if it goes.

I'm also wondering about iceland's other volcanos, they are very close to each other. As the iceland watcher mentioned, lava from Barobara (sp?) has moved into one of the chambers in another volcano, very unusual.

Thanks Publius for listing the watchers site.

Earlier I was reading from another site and they were saying something to the effect of a bulge on one side of this volcanic area where this is all taking place and the measurements was all done using satellite and GPS! Somehow I think there was a misunderstanding or bad translation of the Icelandic language.

I'm reading theres about 3,000. feet of ice on this location thats a little more than 1/2 mile deep covering of ice on the ground and while thats a good bit of ice and should it melt it will not rase ocean levels or at lest not noticeable, but will have an effect on atlantic gulf-stream and if I'm not wrong it will have more of an immediate effect on Europe's weather. The North American Continent will feel it later.
