quote:Voortdurende daling van de caldera is een bron van grote zorg vanwege een mogelijke grote uitbarsting en een gletsjervloed, aldus Vidir Reynisson, director of Civil Protection Agency in Iceland. De verzakking verhoogt de kans op een eruptie in Bárðarbunga zelf.
De lava van de huidige eruptie komt via de magmapijp vanuit de caldera. Hierdoor verzakt de caldera, wat gepaard gaat met sterke aardbevingen in de bodem van de caldera.
De verzakking is nu opgelopen tot 20 meter, zegt Magnus Tumi Gudmundsson, professor of geophysics at the University of Iceland´s Institute of Earth Sciences.
Hij geeft drie mogelijke scenarios aan: Het eerste is dat de huidige Holuhraun eruptie langzaam uitgaat. Het tweede scenario is dat de verzakking doorgaat, evenals de huidige eruptie, mogelijk zelfd vanuit een nieuwe locatie in de buurt.
"Maar het derde scenario is dat de verzakking van de caldera een eruptie start in Bárðarbunga zelf. Zo'n eruptie kan een grote hoeveelheid ijs doen smelten, en kan uitlopen op een krachtige explosieve eruptie met asval" zegt Dr. Gudmundsson.
"Het smeltwater zal misschien niet direct vrijkomen vanwege de vorm van de caldera, maar uiteindelijk zal deze naar buiten komen als een krachtige gletsjervloed. Logisch, dat we ons zorgen maken over deze mogelijkheid"
Dit scenario wordt gezien als zeer serieus, niet in de laatste plaats vanwege het risico van een gletsjervloed, welke uitgebreide schade kan veroorzaken, zegt the director of the Civil Protection Agency in Iceland, Vidir Reynisson.
"Wij maken ons grote zorgen over dit scenario. Als we de geschiedenis van de Bárðarbunga vulkaan bestuderen, zien we grote en krachtige erupties in, en in de nabijheid van de caldera; we moeten dit zeer serieus nemen, speciaal nadat de verzakking was geconstateerd."
Morgen (10 sep) zullen Reynisson en zijn collega's bij het Civil Protection Agency de eerste minister van IJsland, Sigmundur David Gunnlaugsson, informeren over de situatie bij Bárðarbunga.
Vandaag (9 sep) heeft Reynisson een gesprek gehad met de National Power Company, (Landsvirkjun), om te praten over de mogelijke consequenties van een grote gletsjervloed, die waterkrachtcentrales westelijk van de Vatnajokull kunnen bedreigen.
"Zodra de verzakking in Bárðarbunga startte heeft de National Power Company maatregelen genomen om de schade bij een mogelijke vloed te beperken" zei Reynisson. "Als een uitbarsting plaats vindt in Bárðarbunga, is het uiteraard van vitaal belang om de exacte locatie te bepalen, om daarmee de richting van een mogelijke gletsjervloed te kunnen voorspellen. Onze reactie hangt dan af van die informatie."
De caldera beslaat ongeveer 80 Km2, en ligt onder een 700-800 meter dikke ijskap.

Wanneer dat gebeurt, is de eerste en enige prioriteit het redden van de wetenschappers.
Bij een subgraciale uitbarsting duurt het minuten voordat het eerste water komt, en 30-60 minuten voordat er in de buurt van de eruptie zoveel as valt, dat het zicht volledig wordt weggenomen.
Er worden ook al dode vogels gevonden op enige afstand van de uitbarsting.

quote:Iceland grows as Bardarbunga volcano continues to spew lava
VATNAJöKULL, Iceland, Sept. 22 (UPI) -- Iceland's Bardarbunga volcano is a prolific producer of lava, and thanks to its impressive magmatic output, the island nation is growing.
The activity within the Bardarbunga volcanic system is due to the fact that two massive tectonic plates, the Eurasian Plate and the North American Plate, are drifting apart. As they move away from each other, magma underneath Barbarbunga is rising up to fill the gap and helping to grow the size of the country.
The Bardarbunga lava field now stretches more that 14 square miles in size. "That corresponds about to the size of Manhattan," Rikke Pedersen, a researcher with the Nordic Volcanological Center at the University of Iceland, recently told NPR.
You can watch Iceland's growing pains in real time, as two cameras remain pointed at Bardarbunga -- the live feeds are here and here.
In addition to the lava flow, the shifting plates have also caused an extraordinary number of earthquakes. Iceland officials say there have been 20,000 small earthquakes recorded in the last month. It's not clear when all the seismic activity will die down.
Though officials say the last couple of weeks have been slightly quieter than the two before, officials wrote in a recent press release that there "is no significant change in the flow of lava and it is still too soon to say if the volcanic eruption is beginning to fade out."
quote:Bardarbunga volcano update: Eruption continues with steady and large lava output rate
The fissure eruption in Holuhraun continues with similar intensity as during the past days and shows no sign of stopping soon. The latest satellite images indicate that the lava now flows into two main branches, one (the older one) to the north and a new one to the east.
Astonishing lava volumes:
The lava flows erupted since the beginning cover around 37 square km and comprise a total volume of 0.4-0.6 cubic kilometers. If compared to an explosive eruption (for which the VEI scale was designed) using the Volcanic Explosivity Index (VEI) scale, the eruption has already reached the category VEI 5. It has so far erupted about the same volume of magma as the 1980 Mt. St. Helens eruption.
The discharge rate was estimated to 250-350 cubic meters per second. This corresponds to a cube measuring approx. 300 m on its sides. It would be enough to fill a soccer field with a pile 2-3 km tall of lava!
The subsidence of the Bardarbunga caldera continues with same rate as before, approx. 50 cm each day. It has now subsided by almost 30 meters in total.

quote:Iceland releases more sulphur than all of Europe due to eruption
"It's clear that no eruption in the 20th century even comes close to this one. We have to go back to the 19th century to find an eruption that released so much gas. It exceeds all known measurements that we have," says Þorsteinn Jóhannsson at the Icelandic Environmental Agency, when asked about the notable traits of the Holuhraun eruption and the pollution that stems from it.
The eruption has, in only the span of 3 weeks, secured its place in the history books for at least two reasons.
Magnús Tumi Guðmundsson, professor in geophysics, has pointed out that the latest measurements indicate that the lava field is considerably larger than previously believed. The volume of the lava that has emerged from the crack north of the Dyngjujökull glacier is already believed to be at 500 million cubic meters. The surface area is approaching 40 square kilometers. Its thickness is most along the centerline; closest to the craters its 30 meters, but 18-22 meters elsewhere, with the average thickness around 14 meters.
The lava field is among the largest that has formed in Iceland in a long time. Looking back at eruptions in the past 150 years, only the 13-month long eruption from Hekla in 1947-1948 is larger. If the Holuhraun eruption continues with the same force as before, it will reach the same volume as the Hekla eruption in just 2 weeks, writes Magnús Tumi.
But the eruption is also notable for its release of gasses, particularly the amount of sulphurdioxide (SO2). Þorsteinn, who is a geophysicist that specializes in atmosphere quality, says that exact numberrs are unavailable but he believes that the amount of gasses discharged is around 10-20.000 tons a day, though certain measurements show a higher density.
"The gas emissions from Holuhraun are around 10-60 thousand tons of sulphur a day. By comparison the EU nations release 14 thousand tons of sulphur a day, and then we're counting every possible source; industry, energy production, mass transit, heating, etc," says Þorsteinn and adds that in that context the Holuhraun eruption is far from being a minor eruption. Quite the contrary.
The meeting of the Civil Protection's science council yesterday revealed that there are no visible signs of the eruption subsiding in force. The lavafield continues to grow and there is no reduction in volcanic products.
The glacier on the Bárðarbunga caldera has now sunken 27-28 meters since the start of the eruption and the seismicity in the mountain is the same as in recent days.

En de lang verwachte update:quote:12 October 2014 10:00 - from geoscientist on duty
The eruption: Webcameras show no significant changes in the eruption.
Earthquakes: Since 10:00 UTC yesterday (Saturday) two quakes over magnitude 5 occurred in Bárðarbunga. The first one M5.0 at 11:30 yesterday and M5.2 at 08:43 this morning. Both originated in the northern rim of the Bárðarbunga caldera. Additionally, four quakes over magnitude 4 were registered: Yesterday M4.7 at 19:33, M4.1 at 01:36 last night, M4.0 at 03:57 and M4.2 at 06:20. Over 100 quakes have been registered during past 24 hours in the caldera and about 25 in the northern part of the intrusion.
Gas pollution: Northeasterly winds are expected today (Sunday), so the pollution is expected towards south and southwest from the eruption. Polluted area is bounded by Faxaflói in the west and Mýrdalur in the east and is expected to extend north of Hofsjökull. Tomorrow (Monday) wind will be southerly and the pollution will go north.
The Icelandic Met Office provides two-day forecasts on gas dispersion from the eruptive site in Holuhraun. Most reliable are the forecast maps approved by meteorologist on duty. And although still being developed further, an automatic forecast (trial run, see disclaimer) is also available.
11 October 2014 10:00 - from geoscientist on duty
From now on a change is made in these reports from a geoscientist on duty, and they will be published daily at about 10:00 UTC. This may be changed if the eruption changes significantly.
The eruption continues with the same lava flow rate as in past weeks.
Seismicity is similar to previous days:
- There is low activity in the dyke intrusion. Around 20 earthquakes have occurred during the last 24 hours, all within magnitude 1.5 and in the northern part of the intrusion between the eruption site and to the south some kilometers under Dyngjujökull glacier.
- About 80 earthquakes were detected on the caldera rim of Bárðarbunga. The largest earthquakes were at 11:26 and 23:51 yesterday, both of magnitude 4.8. Earthquakes of magnitude 4.7 and 4.5 also occurred and seven between 3.0 and 3.9. Most activity was on the northern caldera rim.
Displacements (no significant changes):
- Minor movements of GPS stations in the area.
- Subsidence of the caldera continuing at similar rate.
Water monitoring: No changes.
Gas forecast (latest forecast 09:32 UTC): Today (Saturday) and tomorrow (Sunday): Northeasterly winds are expected with the possibility of gas pollution south and southwest of the eruption site in an area from Hellisheiði in the west to Hornafjörður in the east.
The Icelandic Met Office provides two-day forecasts on gas dispersion from the eruptive site in Holuhraun. Most reliable are the forecast maps approved by meteorologist on duty. And although still being developed further, an automatic forecast (trial run, see disclaimer) is also available.
10 October 2014 19:00 - from geoscientist on duty
Since midnight, no earthquakes above M5 have been detected in the caldera. The largest occurred during the night (4.7 in size) and half an hour before noon, M4.8. Quite a number of smaller quakes has been detected at the caldera (almost 60 since midnight, the majority at the northern rims). Also in the dike (about 20), from the eruptive site and to about 10 km within the Dyngjujökull margin.
An observation from a surveillance flight with TF-SIF today, revealed great blue mist and gas from the eruptive site to about 3 km height above the crater. From there, it is carried across the South Iceland lowland and across West Iceland as far as could be seen from the aircraft. The pollution seems to be greatest just west of Eyjafjallajökull but is also considerable towards Mýrdalssandur.

During the last 24 hours, about 70 earthquakes have been detected at Bárðarbunga and a dozen in the northern part of the dike. This is somewhat less activity than 24 hours earlier. Two quakes over five in magnitude occurred at the northern caldera rim; an M5.4 at 11:16 yesterday and an M5.0 in the early hours of the morning, at 03:14 today. One earthquake M4.2 occurred later this morning, at 09:25, in a similar location.
Observations of deep thudding sounds were received yesterday while the large earthquake occurred, possibly as a consequence thereof. Scientist went to Askja yesterday but found no signs of a rockfall, which could have caused the noises. Possibly the sounds were from jet aircrafts, passing at the same time.

quote:Lava eruption is second largest eruption in Iceland since Laki in 1783-1784
The Holuhraun lavafield has now reached a size of 70 square kilometers and its volume is thought to have exceeded 1 cubic kilometer, or one billion cubic meters. This lava eruption is thus the second largest in Iceland since the Laki eruption in 1783 - 1784.
"We may be in for the long haul, regarding this eruption," says geophysicist Pall Einarsson, professor at the University of Iceland's Institute of Earth Sciences. "During the last decades, we have experienced eruptions that have been forceful at the start, and rather short lived, such as the Hekla and Grimsvotn eruptions," says Einarsson. "But we can also talk about the Heimaey eruption in 1973, which lasted from January until July that year, and the Krafla eruptions, which lasted intermittently for 15 years. So a long-lasting event in Holuhraun is not a remote possibility; the eruption is now in a well established phase and it's difficult to see any signs of changes."
Bardarbunga still shaking
Seismic activity in the Bardarbunga caldera, south of Holuhraun, still continues, with over 60 earthquakes detected today and yesterday. Limited activity has been detected in the dyke intrusion which is thought to feed the Holuhraun eruption. „As long as there is an eruption there, we see lower pressure beneath Bardarbunga,“ says Einarsson. „Should the magma in the instrusion freeze, we will have to see what happens in the caldera.“
Started small - getting big
With constant activity in the main crater in the lavafield, the Holuhraun lavafield has been growing steadily towards the north and east of the source; reaching 70 square kilometres in recent days. The volume is also impressive; with over 1 cubic kilometer of lava erupted, Holuhraun is now the second largest effusive eruption in Iceland since the 18th century. Only the Laki eruption in 1783 - 1784 is bigger, with 15 cubic kilometers of erupted lava.
"The Holuhraun eruption is accordingly the second biggest effusive eruption when it comes to the SO2 pollution," says Einarsson. That pollution is persistent in Iceland, annoying inhabitants in every part of the country, depending on the weather. 40 - 60.000 tonnes of SO2 are released into the air every day in Holuhraun, and pollution levels have sometimes reached dangerous levels, especially in eastern Iceland.

• Seismic activity in Bardarbunga continues to be strong. The biggest earthquake that was detected since noon on Wednesday, 18. November at 00:26 was of magnitude M4,6. In total 16 earthquakes bigger then M4,0 were detected over the period and 39 earthquakes between M3,0-3,9. In total 170 earthquakes were detected in Bardarbunga since noon on Wednesday.
• On Thursday, 20 November at 08:46 an earthquake of magnitude M1,9 was detected in the dyke. Three other earthquakes larger then M1,5 were detected in the dyke since Wednesday. In total 65 earthquakes were detected in the dyke over the period, which is more activity then has been detected over the past few weeks. Most of the earthquakes were detected in north end of the dyke but about 15 earthquakes, including the larger ones, were more to the south and under Vatnajokull glacier.
• The subsidence of the Bardarbunga caldera and tectonics continues with similar rate as last few weeks. Tectonicsmovements show depression towards Bardarbunga.

• The volcanic eruption in Holuhraun continues to be strong. The lava flow and the gas emission in the volcanic plume is more fluctuating than it has been. There is a double pulse cycle, or fluctuation, one takes hours and the other takes between 10 and 20 seconds.
• Seismic activity in Bardarbunga continues to be strong. The biggest earthquakes that was detected since noon on Friday, were of magnitude M5,1 on Sunday, 23. November at 09:22 and this morning, 24. November, at 09:03 of magnitude M5,4. In total 36 earthquakes bigger then M4,0 were detected over the period and 56 earthquakes between M3,0-3,9. In total about 250 earthquakes were detected in Bardarbunga since noon on Friday.
• First analysis from a new seismograph, which was installed on Bardarbunga on 11. November, shows that the earthquakes in the Bardarbunga caldera originate in the uppermost three kilometres of the earth’s crust. This indicates that the magma is closer to the earth’s surface than was estimated before.
• On Saturday, 22 November, at 00:51 an earthquake of magnitude M1,7 was detected in the dyke. In total about 80 earthquakes were detected in the dyke and around the eruption site in Holuhraun since Friday.
• The subsidence of the Bardarbunga caldera and tectonics continues with similar rate as last few weeks. Tectonics movements show depression towards Bardarbunga.
quote:There are no major changes in the eruption in Holuhraun. From the looks on the web cameras it appears that wall of the crater has possibly collapsed, I don’t have it confirmed. Other possibility is that the eruption in Holuhraun has increased for the time being. Some lava strokes can be spotted on the north edge of the crater at the moment. The lava flow seems to have changed direction at the moment, the size of the lava field is now close to 72 km².

• The volcanic eruption in Holuhraun continues with similar intensity as last two weeks.
• Seismic activity in Bardarbunga continues to be strong. The biggest earthquake that was detected since noon on
Monday, was of magnitude M4,4 on Tuesday, 25. November at 23:26. Since noon on Monday 13 earthquakes larger then M3,0 and in total about 140 earthquakes were detected in Bardarbunga.
• About 20 earthquakes were detected in the dyke and around the eruption site in Holuhraun since Monday. The largest on was of magnitude M1,8.
• No signal is coming from the GPS station in the Bardarbunga caldera, the most likely explanation is icing on the antenna. A flight is scheduled over Bardarbunga today and new measurements of the depression are expected after that.

• Seismic activity in Bardarbunga continues to be strong. The biggest earthquake that was detected since noon on Wednesday, was of magnitude M5,1 this morning, 28. November at 06:41. Since noon on Wednesday 7 earthquakes larger then M4,0 were detected in Bardarbunga and 12 earthquakes between M3,0-3,9. In total about 170 earthquakes were detected in Bardarbunga since Wednesday.
• About 20 earthquakes were detected in the dyke and around the eruption site in Holuhraun since Wednesday. All of them were smaller then magnitude M1,0.
• About 20 earthquakes were detected in Tungnafellsjokull glacier since Wednesday. The biggest one was of magnitude M2,0.
• Scientists flew over Bardarbunga on Wednesday, 26. November. According to data collected in the flight the total depression of the Bardarbunga caldera is 50 meters and the total volume of the depression about 1,4 cubic kilometre since the seismic activity started in mid-August.
• No signal is coming from the GPS station in the Bardarbunga caldera, the most likely explanation is that the subsidence of the caldera is so great that the GPS station is now below the caldera rim and is therefore out of sight of the relay station in Kverkfjoll.

• Seismic activity in Bardarbunga continues to be strong. The biggest earthquake that was detected since noon on Friday, was of magnitude M4,5 on Friday, 28. November at 22:52. Since noon on Friday 12 earthquakes larger then M4,0 were detected in Bardarbunga. In total about 200 earthquakes were detected in Bardarbunga since noon on Friday.
• About 10 earthquakes were detected in the dyke and around the eruption site in Holuhraun since Friday. All of them were smaller then magnitude M1,0. It is worth noting that the seismograph network is sensitive to wind so fewer smaller earthquakes are detected during a stormy weather like the one that has gone over Iceland in the last few days.

• Seismic activity in Bardarbunga continues to be strong. The strongest earthquake since noon on Monday, 8. December, was magnitude M4,9 on Tuesday at 18:00. About 20 earthquakes larger then M3,0 were detected since Monday. In total about 180 earthquakes were detected in Bardarbunga since noon on Monday.
• Little seismic activity was detected in the dyke and around the eruption site in Holuhraun since Monday. It worth noting that the storm, now going over Iceland, reduces the sensitivity of the seismograph system, making it harder to detect small earthquakes.
• GPS measurements show no changes. The subsidence towards Bardarbunga continues with similar rate as has been.
• Telecommunications with the GPS station in Bardarbunga caldera have not been established yet. Due to bad weather forecast it is unlikely that scientists will be able to travel to Bardarbunga in the next few days. A connection will be established with the GPS station as soon as possible.

Scientists have discovered that dyke activity in Bárðarbunga volcano appears to be creating new layers of crust at depth. I don’t have the details on this , I did see this in the news few days ago, but I lost the news about what this is exactly about. I hope to get more details later about this.
