Earthquake, 4.4 in size, measuring in at just over Bárðarbunga half three today. It is the second-largest earthquake since midnight but the sixth time in the morning was an earthquake that was 5 size.
Has slowed seismicity in the area since yesterday. From midnight to noon scored 90 earthquakes. Small changes in crustal deformation north of Vatnajökull.
Tremor of size five became Bárðarbunga the sixth time this morning. The quake was similar to that of other large earthquakes that have been recorded in recent days Bárðarbunga.
Still, the constant seismicity Dyngjujökul according to the Meteorological Institute. About fifty earthquakes have been recorded in the area from midnight.
Seismic eruption has been going on for three weeks, she began three o'clock early on Saturday August 16. According to the IMO have a color change in the eruption of lava pocket since yesterday.
The lava that flows from the vent in the hole lava has reached Jökulsá the mountains by day take it at the same pace over the last day and says volcanologist at the eruption site. Little power in the eruption that began the previous night next glacier.
Continue shaking the Bárðarbunga there was tremor of size 5 in the morning.
"As we tested it just now let him leave the range of 900 to 1000 meters in the ice sauna," said Thorwald Thordarson volcanologist lava advocating my approaching Jökulsá the mountains. "He's like something between 40 and 50 meters per hour. So in that way he sirkabát day into the river. "
Bardarbunga has sunk about 15 meters in the metabolism lately. "We can say that it does not reduce the likelihood that a potential eruption, and even significant, in itself, a box or Bárðarbunga itself," said Magnus Tumi Gudmundsson, a professor of geophysics at the University of Iceland.
Scientists perished in a plane eftirlitsflug Isavia yesterday. She has been equipment for research and discussion was the data last night and last night. "Then came the rather unexpected finding that Bárðarbunguaskjan has subsided by up to fifteen meters, so that the ice has reduced by this amount," said Magnus Tumi. He says that the most likely explanation lies earthquake Bárðarbunga related to caldera has sunk to the bottom. There has been a volume equivalent to a quarter of cubic kilometers. "It is himself that we have not seen volcanic activity since records began in crustal deformation in Iceland and it was the middle of the last century. And probably need to look further back before we see similar moves. "
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.
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.
5 September 2014
Satellites are showing clouds of sulphur dioxide from Iceland’s restive Bardarbunga volcano.
ESA’s Volcanic Ash Strategic Initiative Team (VAST) and Support to Aviation Control Service (SACS) are monitoring the situation closely, and have detected sulphur dioxide emissions since early September. A small cloud of sulphur dioxide has been drifting toward Europe since late last night.
In the surveillance flight yesterday the ice-surface at Bárðarbunga was measured with the radar system of Isavia’s aircraft. The measurements show large changes on the ice-surface. Up to 15 m subsidence has occurred in the centre of the caldera, which corresponds to a volume change of 0.25 km3. The shape of the subsidence area is in accordance with the elevation of the caldera floor having lowered by that amount.

I shot this handheld from the wrong side of the helicopter, over another the shoulder of a guy who was shooting the whole thing on a RED camera and using stabilizing equipment so please excuse the shakiness of this video.

15 kilometers, too, is the reason that people in Ireland tomorrow will only be getting toxic-pretty-sunset-gas rather than being part of massive transatlantic air traffic jams.
It's time for Eldfjallavakt.
The winds are changing:
As recalled by Jacques-Marie Bardintzeff in his blog Volcanmania , there is a hot spot in the Iceland . This makes the island a paradise for volcanologists in the world as loved to tell Maurice and Katia Krafft . We have no difficulty in believing when we see images of the eruption fissure in the field of washing of Holuhraun (which translates to "lava desert holes") along the volcano Bardarbunga. She first took a few hours August 29, 2014 before flare Sunday, August 31. Two new fissure eruptions began Friday, Sept. 5, 2014.
The rash that has developed in recent days, has evolved, as you have read in our last editorial , and now there are two fissures that are expelling lava. The southern fissure is much closer to the glacier, and this increases the fear that the eruption could start even under the glacier itself .
In the surveillance flight yesterday over the area of Bardarbunga was a subsidence occurred on the glacier up to 15 meters, right in the center of the caldera, which corresponds to a volume change of 0.25 km3. In the shape of the subsidence is in agreement with the elevation of the floor of the caldera, which is lowered by that amount.
"Another picture of the day that has fascinated me is a photo taken on the western edge of the graben, which made its appearance on September 3 : an example of what geologists appèlent a normal fault. The recess, which is the height to which the movement is carried out is several meters."
The lava comes about one mile per day, almost eleven miles to the north and yesterday afternoon covered the sixteen square miles of land. Volcanic activity in the same places as before, according to a status report scientists from the Council for lunch. There was a low level of activity in the crack opened up on Friday if it is compared with the northern rift has been active from the beginning.
The Environment Agency has been to measure sulfur dioxide pollution in the region after the eruption. Thorstein Jóhannsson, an expert at the Environment, says the values measured to be high enough that people who are sensitive to the need to have a backup.
Thorstein said hádegisfréttum measurement of plant yesterday had shown high concentration higher than they were accustomed. Those who may be exposed to people who are vulnerable, such as people with asthma, senior citizens and children. This should not affect healthy people. "You would not advise anyone who is sensitive to pass strenuous outdoors," said Thorstein, naming útihlaup and difficult gardening as an example of what people who are vulnerable should be avoided.
"We are well below occupational limits refer to working people in the workplace, such as in heavy industry."
Moda seen on satellite images that IMO uses and give the impression that Blur is from the eruption. It could contain sulfur and other undesirable substances.
An attempt was made to measure the ingredients and their concentration in the evening but the instruments that are on the site were not sensitive enough. The meters were used except nothing under 290 micrograms.
Environment sent the measure east today to analyze materials in Maternal and strength. Thorstein Jóhannsson, an analyst at Environment Agency hopes that the results of measurements are available in the evening. "All we have in hand indicates that this is a mocha from the eruption. It is very interesting and useful to know how much strength he has done. The information we have now, and the pictures I've seen indicate that it is then that gráblái sulfur likeness on it. View, one would estimate that this would be like in contaminated metropolis. This is not terrible pollution to see but it is very important to get the measurements and we will try to get it now after. "
The new lava field at the Holuhraun eruption is now advancing into the westernmost branch of the Jokulsa a Fjollum glacial river which runs from the Dyngjujokull outlet glacier. The output is estimated to be 100 - 200 cubic metres per second, and the new lavafield covers about 16 square kilometres.
This is according to a new status report by the Icelandic Civil Protection´s Scientific Advisory Board, published today.
Scientists monitoring the eruption estimate that the advancement rate of the lava flow is about 1 kilometer every day. The volcanic activity in the main fissure has remained steady, but the small fissure to the south, which opened up on Friday has diminished.
Lava flow from the blowout lava goes faster than yesterday but today is 80 to 100 meters per hour, where he runs into Jökulsá the mountains, said Thorwald Thordarson volcanologist. Steam coming out of the lava as it crosses the water evaporates in the heat.
Researchers at the scene were well aware that the lava would come in the riverbed when they were on their way from the Dragon eruption early this morning and announced that the Institute of Earth just over seven.
Thorvald Thordarson volcanologist said in an interview with news agency that they had been overheard this, "when we get a URL to the Vaðöldu we found gufubólstrum from eastern flood. It was pretty clear that the lava had gone into the riverbed and the river. We then drove down to the lava eventually. Then we saw it and were able to confirm that the lava had reached the river. It has risen from the small gufubólstrar and really nothing much going on so seen. The lava continued his progression as it has happened and part of it came into contact with the river and was not a little vapor that rose from the lava. "
