The volcanic area near Bárðarbunga is erupting

A fissure eruption has started north of Dynjujökull, seen in the photo. A live YouTube stream is available below

Authorities in Iceland say the fissure is ~10 km north of Vatnajökull and currently measures about 100 meters long. The eruption started shortly after midnight on August 29 in Iceland, however the eruption seems to be subsiding in recent hours.

40!

40?

Anything is possible
Greg

Thanks, my telepathy is always a bit weak before my first coffee.
Actually, I think pathetically small non tropical volcanoes was implausible excuse no. 2 for the ‘pause’.
In fact major stratospheric eruptions were the cause of a large part of the late 20th century warming. The lack of major eruptions is the reason temps have been fairly flat since.

2!

Greg

indeed. Having found out what 40! was, I realise you are saying the same thing as my comment:
“Actually, I think pathetically small non tropical volcanoes was implausible excuse no. 2 for the ‘pause’.”

Greg

At least we have half a chance of pronouncing the name of this one.

Jenn Oates

My son and DiL have a lovely Icelandic friend who assured me that they can’t pronounce the names of some of those volcanoes, either. That made me feel somewhat better. 🙂

Greg

Oh, I’m sure I would get close to pronouncing it correctly but that’s not what I said.
The last one that made the news was called something like Ekjlasodiagnpoanbeacvu. Which even after looking it up and finding an mp3 and hearing it, I could not utter.

tty

How could anyone possibly have any problem with pronouncing Eyafjallajökull? It is pronounced just as it is spelled. The only difficult points might be the “ö” which sounds more or less like the vowel in “girl”, and that vowels followed by double consonants are always short in Icelandic (and other North Germanic languages).

Greg


Thanks for the tips but even if try eating an apple and strangling myself at the same time, I don’t think I could make a sound like that.
I can manage welsh railway stations if I concentrate by icelandic volcanoes are beyond me. 😉

It could be worse…it could be in Welsh.

Richard G

I prefer to just call it Bunga.

ozspeaksup

Kowa BUNGA!! surely? 🙂

Then we call the crater Bunga Hole.

Andyj

And if it is noisy. Bunga Din! (Carry on up the Kyber)

Richard G

Those are all good nicknames and as a bonus, they are easy to pronounce.

tty

The “á” is pronounced rather like the vowel in english “call” and the “ð” (the fourth letter in the name) is a voiced lisp similar to the initial sound in english “this”. Otherwise it’s plain sailing.

Martin Hall

The Icelandic letter ‘eth’, ‘ð’, is similar to the Anglo Saxon ‘thorn’. this is still to be seen in a debased form as a ‘Y’ on shop signs in the UK, especially England. If you see ‘Ye Olde Tea Shoppe’, the first word is actually ‘The’.
Quite a good summary on Wikipedia:
http://en.wikipedia.org/wiki/Thorn_%28letter%29

lol try this one

Warning: insufficient number of vowels.

I think that in the dark of night some time ago, the Finns stole all the vowels from Wales… how else could they have enough for their heavily umlauted (double dots, e.g. ä, which is ae) language? I mean, really, they often have strings of double umlauted vowels
(pääsisivätkin as a small example from an article on volcanoes in Wiki), almost like
nya (nyää?), nya, nya, got your vowels and I’m not giving them back 🙂
Icelandic seems to be similar (looking at some of the articles on “the Bard”…today).

Quick, grab the marshmallows! It’s time to make s’mores!

Good Comment, magma is simply moving — Wow the scale of it is amazing.

On the other side of the world, a volcano erupted in Papua New Guinea, causing a population exodus from nearby.

ozspeaksup

ah but in every dark cloud..
the silver lining might be that the aerial debris causes some rains for the drought areas of qld etc
we can hope.
and some speccy sunsets soon:-)

Rabaul is a very bad place to put a town, there being several very active volcanoes all around the place. However it has one of the best natural harbours in the World, in an area where good harbours are very scarce.

David L. Hagen

Thanks Tom
Coconut palms usually recover in about 2-3 years.
In preparing a business plan I found the volcanologists expected the Rabaul volcano to blow about every 113 years or so (as I recall) and at the time were only about half way thru that. Well about 2 years later it blew. Now “it” is blowing again 20 years later.
So much for “average eruption frequency”!
or may be those are “different” volcanoes?

islander

MOST sites world-wide CENSOR ANY providence talk, except this one!!! Large eruption of Rabaul volcano, Papua New Guinea. 18km ash could and air flights rerouted: AVERTABLE!
The proposal says: widen the crater in case of an eruption”, that means bombing will NOT cause any eruption, tactical weapons will NOT worsen any condition, instead widening an exit hole decreases speed flow, thus we will NOT face the results of another air-traffic chaos, taking also into account that Bardarbunga gave in 1477 a very strong SIX VEI eruption, adding to the longitude of the Little Ice-age!…

joelobryan

tides are driving the magma flow.
by Monday they reach a peak. If the caldera doent explode by Tuesday, it wont in this cycle.
Hofn is the nearest tidals charts. It is about 95 minutes ahead of the tides at Bardarbunga.

joelobryan

the other more important factor is pressures within the magma. once a relief to atmospheric pressure is found, just like a dropped but closed beer bottle it is relatively stable. but once you open it to atmospheric pressure, the gases want to evolve out. A fizzing bear bottle that runs over the top. Icelandic magmas are known for their high content of dissolved gases.

Patrick

There is an erruption in PNG too, don’t have any detail, but 18km ash could and air flights rerouted.

Unmentionable

That cone has a nasty history of repeated major lateral blasts that extend put for 30 km radius on average, but it is just a lump of poop on the rim of a huge caldera siting under the water beside it. Look out humanity if that one ever gets active again.

icelandic volcanicity is highly complex.

Bill Illis

Large eruption today as well at the Tavurvur caldera on the eastern side of New Guinea. This caldera has a long history of small eruptions but also an occasional VEI 6 and, then given it is a large caldera, much larger eruptions would have happened in the distant past.
Impressive lava fountain and it is in a populated area.

http://www.livefromiceland.is/e/

This was a very very small eruption that lasted only a few hours. Only a very small amount of lava is visible.
It was so small that it has no effect on the volcanic activity in the Bárðarbunga-Askja region.

Wonderful 3d visualization of seismic activity here:
http://baering.github.io/earthquakes/visualization.html
This way you can get a very clear view of the fissure structure.

Interesting web showing GPS measured displacement and earthquakes:
http://en.vedur.is/earthquakes-and-volcanism/gps-measurements/bardarbunga/

Three areas of activity.
There is the beginning of a NE lineation of activity, NE of Askja.
It is not as active as the area midway between Bardarbunga and Askja.
And the quakes bigger than Mag 3.5 quakes for the past 48 hrs are all under the Bardarbunga crater.

Past 4 hrs:
A 3.1 and 3.6 in the Bardarbunga crater.
A 3.1 and 3.2 midway to Askja. (at least 10 above Mag 2)

Early this morning:
http://www.mbl.is/tncache/frimg/dimg_cache/e392x262/7/61/761734.jpg
A second fissure eruption started in an ice-free area north of Bardarbunga, early Sunday morning. The eruption is located at the same site as an eruption Friday morning, which lasted only a few hours.
The Icelandic Met Office has issued a red alert for aviation, restricting flight around the eruption site.
The eruption seems to have started near the northern end of the magma intrusion that has been propagating northward from the Bardarbunga caldera since August 16.
RUV.08.2014 06:41, Updatet: 31.08.2014 07:33 GMT

It is visible now on the webcam. Wind caused by the hurriicane Cristobal shaking the camera.
http://www.livefromiceland.is/webcams/bardarbunga-2/

Now the lava flow rate is estimated to be about 1000 m3 per second. About 50 times more than during the short eruption on Friday.

News report with a 30 second video attached, mostly lava advancing toward the camera
Eruption continues at full force – video
From the article: 8/31 18:37 GMT

The eruption started around 04:00 GMT Sunday, on the same fissure which erupted Friday.
Sunday afternoon, the eruption showed no signs of subsiding.
According to scientists, the latest eruption is roughly the same size as the one at Eyjafjallajokull in 2010, which grounded flights throughout northern Europe. However, no volcanic ash has been detected on radar
Updates in English will be posted at: http://ruv.is/volcano Follow us on Twitter: @ruvfrettir

Past 8 hrs: A 5.1 and a 4.9 mag quake at the Bardarbunga crater.
Lots of small ones at the vent midway between Bard. and Askja
There is a growing collection of Mag 2-3 quakes NE of Askja.

Correction: The nested blockquote “Past 8 hrs:”, should have been normal block. They are my notes.

It’s 08-31-14, 11:52 ET….this thing is going to pop within the next 48 hours! probably less!

From a collection of photos on Facebook account Jarðvísindastofnun Háskólanscomment image

Past 24 hours:
At Bardarbunga Crater: A Mag 5.0 and 5.3, two Mag 4+s, four Mag 3+ (5-10 km depth)
At the midway rift, 1 Mag 3.0 13 hrs ago, one other above 2.4 (10-15 km deep)
At the new active zone NE of Askja: (65.15 N 16.35 W) A Mag 3.1 12 hrs ago, eight other quakes above 2.4. All are shallow, less than 5 km.
Slabby Pahoehoe lava – and lots of it140901 20:19 UTM

According to a status report from the Institute of Earth Sciences today, the current eruption is believed to have produced until now about 20-30 million cubic meters of lava at a rate of 100 cubic metres per second.

Fissure is about 1.8 km long. Lava covers 4.5 km^2. Flow is 7-8 m thick at the cool edge, 1 m thick where it is hottest and most liquid.

Correction to 4:04pm:
at 20:19 UTM GMT. (Or UTC. UTM is a map projection)
check: if there is 30 million m3 of lava in two days, that would be an average of 174 m^3/sec.
Bardarbunga slowly sinking
The big Mag 4-5.7 quakes at the Bardarbunga crater, along with GPS measurements are signaling that the crater is collapsing into the magma chamber as the magma leaves the chamber to feed the dike intrusion.
the top of the volcano is sinking ever so slightly.”
They make no mention of the amount of sinking. But to account for 30 million m^3 of lava, even if Bardarbunga was 10 km by 10 km, it would have to shrink by 0.3 m if the volumes are to match.

Holuhraun lava eruption rapidly subsiding 140901 13:01 GMT.

The volcanic activity in Holuhraun appears to be rapidly subsiding according to geologists…..
There is quite a lot of seismic activity in and around the north of Vatnajokull. About 500 earthquakes have been detected since midnight last night and the strongest activity is around Dyngjujokull glacier as has been the case in the past few days.

It is late afternoon on the webcam. No red fountains are visible. Consistent with declining activity, but it could be the lighting conditions.
There are great pictures for good wind direction from Sept 1 in the link above, but it looks to me like the fissure is much shorter than yesterday.
From the http://baering.github.io/, there has been a remarkable decline in the activity from the area NE of Askja.
In the past 22 hrs
at Bardarbunga, a 4.7 and 4.3 in the past 5 hrs.. only a few small ones.
at the mid-way rift, One mag 3.1 15 hrs ago, 4 others above 2.5, and lots of small stuff.
NE of Askja, 5 between Mag 2.5 and 2.9, but all older than 12 hrs. In the past 12 hrs it is all small (biggest is 2.2) and quite scattered along the rift.

Since about 140902 14:00 GMT the earthquake rate has fallen dramatically. Look at the rug plot below the map.
http://en.vedur.is/earthquakes-and-volcanism/earthquakes/vatnajokull/
Compare these Snapshots of the 48 hour earthquake maps from:
Aug. 29 02:25 and Sept 2, 17:55
Activity is definitely in a decline phase in frequency, magnitude, and area.

The webcam http://www.livefromiceland.is/webcams/bardarbunga-2/
It is now late afternoon, and red fountains are visible from what appear to be two inline fissures.

I see that the talk is saying that an eruption in the crater of Bardarbunga is still on the list as a possibility. They just had another 4.9 mag quake about 20 minutes ago, and there were several more earlier today. Could be sooner rather then later.

This must be the best 3D visualiaztion model of the earthquakes under Bárðarbunga.
It is made by an Icelandic 24 year old programmer Bæring Gunnar Steinþórsson.
Fly from above the glacier and through the surface to see what is going on underground.

I was looking at that last night. Although, I did not realize that you could look under the ground with it. What a great tool for understanding the movement and effects of the magma intrusion. I was just reading at RUV where they have pulled back all personnel to safer locations today.
Here is a picture of a rift valley forming from the pressures being exerted…http://www.ruv.is/frett/holuhraun-eruption-not-big-enough

Last 24 hours: 4 mag 4+ quakes (no Mag 5+) under Bardarbunga.
Only 2 Mag 2.4 quakes near the fissure, 4 bigger than 2.2.
Nothing bigger than 2.3 NE of Askja. six bigger than 2.2.
Last 8 hours: 2 Mag 4s at B
two 2.0s at the mid-way spot.
four mag 2.2-2.3 NE of Askja.
Up to 130 meter high lava fountains Sept 4 14:09 GMT.

“The highest lava fountains rise up to 130 meters from the craters,” he says. The new lava field is now estimated to be 11 – 12 square kilometers in size. ….
The fissure itself has not changed much however; it´s still 1.7 – 1.8 kilometer long,” he says.

(Full) frontal breakout of Pāhoehoe lava Sept. 4 16:33 GMT.

Visual observations today indicate that the size is now 10.8 sq. kilometres. Estimated volume of the lava is 45 – 70 million cubic metres.

A Facebook post from Institute of Earth Sciences

The intensity of the ongoing eruption in Holuhraun is not declining. Lava is flowing toward ENE and it has been elongated considerably since yesterday. Since this morning, a preliminary estimate of lava field extension is about 10.8 km2.

Everything Changes When Night Falls 9/4 23:38 GMT
Has a video of night lava fountains and flows.

Last 8 hrs, things bigger than Mag. 2
Three at Bardarbunga, biggest 2.8, 30 minutes ago.
One at the mid way point, Mag 2, 9 km deep, 4 hrs ago.
One NE of Askja, Mag 2.1, 2 hrs ago shallow, 2 km.
What is new is there is a string of low mag quakes running SW of Bardarbunga.

Last 15 hrs: One Mag 5.3 at Bardarbunga, Nothing bigger than 2.3 other than that.
Between Mag 2 and 2.3:
Three at Bardarbunga, two at mid-way, four NE of Askja.
Below Mag 2, there is a pronounced “pipe”, and maybe a second one, at the midway fissure than goes to about 12 km. This had been more of a sheet in previous days, but today the quakes are stacked in a restricted pipe.
There are about 4 subareas of activity NE of Askja along the same rift.
New fissures erupting in Holuhraun 9/5 08:56 GMT

Two new effusive fissures have opened up in the Holuhraun eruption, about 2 kilometres north of the Dyngjujokull outlet glacier. ….
The two new fissures are about 1,5 kilometres south of the previous eruption…..
Volcanologist Thorvaldur Thordarson, who is nearby, says clear that the eruption has changed; the eruption is now spreading to a new fissures, closer to the Dyngjujokull glacier. Large new surface cracks have been observed there in the last days, and a small rift valley (graben) has formed, which extends under the glacier.

See molten lava crawl over the sand
Contains a 2:45 video of fountains, lava flows, a time-lapse of lava.

Holuhraun lava field now 16 sq. kilometres
The lava flow is a few hours now from on of the rivers that run off the glaciers. So some lava-water fireworks are in store for us.
Lava output is estimated between 100-200 cubic meters per sec, so it hasn’t changed in 5 days. The main fissure has remained steady. The small fissure that opened up Friday has diminished.
Earthquakes are way down.
Last 36 hrs, five quakes between Mag 3 and 5.4, all at Bardarbunga
Between 2.4 an 2.5: two NE of Askja, one W of Bardarbunga.
At the fissure, the midway group, the largest is 2.2 and 10km deep. Three above 2. Lots of Mag 1-2, and more scattered, maybe in three planes.
