Hawaii Volcano warning
Sept 5, 2014  
Hawaii issued a warning Thursday to Kaohe Homesteads community in the path of a Kilauea lava flow on Hawaii Big Island, as the molten rock moved to within a mile of homes.

I find it interesting that both the Pacific volcano and an Atlantic volcano in Iceland are both spewing lava this month.

Great photos of Iceland volcano

Lava Rising in Iceland
Sept 6, 2014  Bardarbunga Volcano
could soon have a Violent Eruption

Jon Frimann Sept 5-6
There is high risk of new fissures opening in the rift valley without warning.

Holuhraun lava heading for glacial river
Within 24 hours, lava flowing from the Holuhraun fissure will enter the one of the branches of Jokulsa a Fjollum glacial river, if the advancement rate remains the same, says volcanologist Thorvaldur Thordarson. Volcanic activity in Holuhraun has not diminished since yesterday.

"The lava field has been advancing towards the westernmost outlet of Jokulsa a Fjollum glacial river, with a rate of about 40 metres per hour," says Thordarson, who is observing the eruption in Holuhraun along with collagues from the University of Iceland´s Institute of Earth Sciences and the Icelandic Met Office.

"If the lava flow remains steady, we should see the lava entering the riverbed sometime in the afternoon tomorrow," he says. "I do not expect much explosive activity, but we should however see some violent magna/water interaction when the lava meets the glacial runoff."

The glacial river runs from the Dyngjujokull outlet glacier in several branches; the branch which the lava is heading for is one of the larger ones.

According to the most recent status report from the Civil Protection Agency´s Scientific Advisory Board, the volcanic activity in Holuhraun has remained steady. The main eruption is at the fissure which opened last Sunday; less so in the smaller fissure to the south, which started erupting early yesterday morning.

Seismic activity has decreased since yesterday, with appr. 90 earthquakes detected since midnight. As before, the strongest events are happening in the Bardarbunga caldera; at 05,40 GMT a magnitude 5 earthquake occurred in the caldera. At least 14 earthquakes of magnitudes greater than 5 have been located since 16 of August.

Bardarbunga caldera
Sept 6, 2014
About 250 million cubic meters of magma have flowed out of the chamber, belived to be under the Bardarbunga caldera, leading to a 15 meter subsidence of the caldera itself. These changes are clearly observed on the surface of the glacier covering the volcano, say scientists.

This was observed yesterday with radar measurements during a surveillance flight over Bardarbunga, and the Dyngjujokull outlet glacier to the north.

According to a status report issued today by the Icelandic Civil Protection Agency´s Scientific Advisory Board, those measurements show dramatic changes on the surface of the glacier. In the center, the Bardarbunga caldera, beneath, has subsided by up to 15 meters. This corresponds to a volume change of 0.25 cubic kilometres, or 250 million cubic meters. According to the report, the shape of the subsidence matches the elevation of the caldera floor under the 7-800 meter thick ice having lowered by that amount.

Never seen before

"This much subsidence has never before been measured in Iceland," says geophysicist Magnus Tumi Gudmundsson, a professor at University of Iceland´s Institute of Earth Sciences in an interview. "We believe that the strong earthquakes in Bardarbunga are signs of this subsidence. We see no signs of eruptions or geothermal activity in the caldera itself, but this subsidence does however not decrease the likelyhood that something could happen in Bardarbunga," says Gudmundsson. "One theory is that the bottom of the caldera kind of floats on the magma below, and helps to push it out towards the dike intrusion, which is feeding the eruption in Holuhraun."

Not since 1875

"We have not measured an event like this before in Iceland," says Gudmunsson. "We probably have to go back to the formation of the Öskjuvatn caldera in Askja, in 1875, when a large explosive eruption occurred there. That event was of course much larger, with subsidence of about 300 meters, but the current one in Bardarbunga is ongoing, and very significant."

Cauldrons signs of small and short eruptions

During the surveillance flight yesterday, a shallow, wide depression was observed on the surface of Dyngjujokull, 10 kilometres from the glacier edge. Another depression, 6 km. from the margin of the glacier, in line with the dike intrusion, has deepened to about 35 metres. Scientists say likely that these cauldrons are signs of small and short-lived eruptions beneath the glacier.

Sept 8 Monday  just after 6 am eastern USA time
A sudden earthquake as I watch cam2
Then rocking like a boat on the sea  (almost nauseating  rock rock rock)
I had seen a couple jerks on cam prior
I have NO idea whats happening.  
I see white and dark and very dark  clouds rising - more rocking - egads

Bárđarbunga volcano Eruption update
September 5-7, 2014
by Jón Frímann
New cauldron has formed some 6 km in Dyngjujökull glacier. The  glacier in the that area is 300 to 350 meters thick. Last report was that this cauldron was getting deeper during the day.
Smell of rotten eggs
The air around the eruption site is toxic due to release of SO2, CO, CO2, fluorine gases and other dangerous gases.
The water vapour cloud goes up to 4,5 km according to latest measurements.
The SO2 goes the way of the wind direction

Updates for 06-September-2014
Bárđarbunga volcano has lowered some 15 meters since 16-August-2014.
A new cauldron was also found some 10 km from the edge of Dyngjujökull glacier.
Blue mist has been seen today in east Iceland.  (sulphur)

Updates for 07-September-2014
The flow of magma is currently 100 to 200 mł every second.
The new fissure has stopped erupting according to latest news.
There is a high risk of new fissure opening up in the erupting area without warning.
The lava field has reached Jökulsá á Fjöllum glacier river. Lot of steam.
Bárđarbunga volcano caldera continues to sink.

Interesting writeup

There is a blue sulphuric mist in the air in Iceland - NOT good

3 new craters as of Sept. 8
I was surprised to see a lake in a crater.
Öskjuvatn Lake Askja Caldera
Helicopter video panned I saw a lake and took a snip.

Live volcano cam

Sept 9, 2014
Cam 2 - The steam is not going right or left - no wind?
Cam 1 - Last nite I saw R2D2s friend next to him, and later I saw his friend leave, VERY bright headlights!
I see puffs of steam below blowing to my right.
I look fullscreen once in awhile - AWESOME!  One day earlier I thot I saw something small and pale colored scurring near R2 on cam 1.  Didnt it get the memo?

Decided to view both cams before posting.  Shaking again.
Cam 1 - steam appears to drift both right and left ... errr?
Cam 2 - Huge steam column drift left,  lesser steam behind drifting right.
Shaking some more, small quakes I presume, but could be wind

R2D2 is a radar placed there. A scientist in a jeep checks it.

Bardarbunga subsiding
Sept 9, 2014  Jón Frímann

Slow caldera collapse, the largest one measured in an Icelandic volcano.
15 meter subsididence in the center of the caldera.
A surveillance flight over the Bardarbunga volcano this morning revealed continuing subsidence of the 850 metre thick glacial ice which covers the caldera beneath.

Possible eruption under the glacier might have started in Bárđarbunga volcano
I think that eruption has started under the glacier in Bárđarbunga or maybe in the dyke area.  Unconfirmed!

Third cauldron

Bardarbunga volcano
September 11, 2014  -  My observations  on 9-11
Holy cow!! Cam 2 is totally different! It doesnt look like the same picture!
something went past from right to left.
Maybe helicopter but I went small screen reading above and couldnt tell.
All I saw was a ball of light.
OK it flew back so I went full screen and over to cam 1.
Saw an aircraft fly left to right. I imagine a small plane, scientists – just a guess.
Nope. Not a UFO, not a shuttlecraft.  Wink I watch too many space movies!

THAT was definitely a helicopter – just now – on cam 2 – flew right to left – slowly –
and it was real low and real clear!

Caldera collapse is in progress in Bárđarbunga volcano
September 10, 2014 by Jón Frímann

Scientists in Iceland don’t want to mention this in the news and are still hoping for current sequence of events to stop. That is not going to happen, all that can be done now is to plan for the eventual collapse of Bárđarbunga volcano into a new caldera.  Eruptions should also be expected without warning around the magma chamber that is collapsing in Bárđarbunga volcano.

Bárđarbunga volcano is however not going to collapse quickly, while the eruption once it starts in Bárđarbunga volcano is only going to last 1 week at the longest. This type of events takes several weeks to months from start to end. There is no way to know for sure how long this is going to take.

SO2 levels in populated areas in east Iceland did go up. Health warning was issued for the area during the peak of the SO2 pollution.
The caldera has now dropped some 20 meters.
There continues to be earthquake in the dyke, most of it is in area that is covered with glacier.
Eruption in Hamarinn (Loki-Fögrufjöll) volcano is now a possibility.

Sept. 12, 2014  dawn in USA - my observations
If I lived on Iceland I would leave NOW - with any animals.  I would not wait until Pompeii

I cant see anything on cam2 and not much on cam1

Here is an American blog with an article, comments and a very good video.
This video looks like it may have been taken by the helicopter I saw flying low back n forth on cams 1 and 2 yesterday.

Image - MAP
That website has this map - you may want to save it

It Will Be Unlike Anything Ever Seen in Recorded History
"This is lava draining out from under the crater of Bardabunga 25 miles away!
The scale of what is going on is unlike anything seen in modern times.

"The lava under the Bardabunga crater is draining out from the crater floor (the Caldera) which is over 6 miles in diameter and filled 2500 feet thick with ice covering the crater floor.

"That FLOOR has dropped 25 meters (80 Feet) this week.

"Scientists are now gravely concerned that the crater floor will soon collapse into a miles deep underground cavern filled with boiling white hot magma.

"There's 1 trillion gallons of water in the ice in Bardabunga crater.

"When that falls into a lake of magma it will instantly flash into steam expanding 600 times in volume.

"The magma, suddenly no longer contained by the crater floor and 1 trillion gallons of water will act like a shaken soft drink can when the top is popped.

"It will be an event unlike anything ever seen in recorded history.

The current eruption is happening on a fissure that is located a tiny bit North-East of Bárdarbunga. The fissure is not located under Vatnajökull which is Europe's largest Glacier. Bárdarbunga is located under this glacier and that is why it's causing concern.
This eruption is happening more than 100 miles away from Reykjavik in the SE portion of the island.

Aviation colour code map
Askja - yellow and Bar still orange, no other alerts
Warning -  Fissure eruption in Holuhraun (north of Vatnajökull).
Warning -  A high concentration of sulphur dioxide is forecast from the Holuhraun eruption. Air pollution is likely in the East Fjords, extending north to Vopnafjörđur. This is valid for tonight and tomorrow (Friday). A larger pollution area cannot be ruled out.

Status update on Bárđarbunga volcano
September 12, 2014  by Jón Frímann
at 22:11 UTC
I have been seeing harmonic tremor spikes all day today. I have traced them to Bárđarbunga volcano.
The new caldera that is now forming in Bárđarbunga volcano is a large event, since Bárđarbunga volcano is a large volcano.

Lots of articles here

Sept. 13, 2014
Rúv radio blackout alert
I see toxic smoke blows at least 2 directions.
People in that village and nearby area advised to stay indoors and don’t go outside.

Only stay indoors?  Gasses go thru homes, a mask not much help.
Evacuating the entire island of humans and animals would take lots of TIME - and if Bar blows, no air evacs.  If I am reading writeups correctly - shouldnt evacuations have been occuring?

Bardarbunga daily update
24 September 2014
The lava field is now around 40 square km in size.
It is now second largest lava field in Iceland.
Bardy caldera sinking.

Bardarbunga daily update
28 September 2014
Snowstorm yesterday.
Magma continues to flow into volcano.
The lava field is now larger than 40 square kilometres.
Bardarbunga caldera continues to drop around 50cm/day.

RUV has a great video with great information for newbies to volcanoes - like me!
I am sort of both a newbie and an oldbie I guess.

Bardycam 1 had white SNOW! this morning.  Quite a site with my coffee today.

Vedur warnings posted
Sunday gas pollution from the volcanic eruption is expected towards the east and southeast of the eruption site.
Tomorrow (Monday) the pollution will affect areas to the north and northwest.
A strong gale (more than 20 m/s) is expected widely tomorrow and heavy rain in the southeast

Some blogs post Iceland is splitting along the Mid-Atlantic Ridge.
I websearched because the quake pattern on vedur looked like Earth was splitting along the ridge.  I have observed earthquakes all down that ridge.  The South Atlantic has had some huge quakes the past year or so.   I dont believe this should be discounted.

Earthquakes North Sea
October 12, 2014  
SON[/b]day  -  Iceland - Greenland area has a lot of medium quakes between 4.0 and 5.2 SW of Reykjavík, Iceland.  Bardy volcano has been erupting and there have been a number of earthquakes all along the Atlantic fractuze zone clear down to the South pole.

Bardarbunga volcano
Oct. 12, 2014
 SONday - dawn USA
Bardy is shrouded in a veil, I cant see a thing on either mila cam.  
There are a lot of NOT small quakes in the Iceland area.
I saw Jon mentions magma in the Tskul volcano next to Bardy but vedur has not changed colors.
