Daily Bárðarbunga volcano update on 18-September-2014

This information is going to get outdated quickly.

Current status on Bárðarbunga volcano at 20:36 UTC

Largest earthquakes in Bárðarbunga yesterday (17-September-2014) was a magnitude 5,2. Largest earthquake today (18-September-2014) was a magnitude 5,3. Other earthquakes have been smaller.
Bárðarbunga volcano caldera continues to drop. When the magnitude 5,3 earthquake happened today at 14:21 UTC the caldera dropped 20 – 30 cm.
GPS data (more GPS data can be found here) suggest to me that the dyke at Vonarskarð might be getting ready to erupt or getting re-activated. It formed in the first two weeks when current activity started in Bárðarbunga volcano on 16-August-2014. It is already there, it however failed to start an eruption, but as I say, it might be getting ready to get active again. This has been followed by some minor earthquake activity. There is however a more complicated picture into this. The details can be found later in this article. [Please note that due to licensing issues I only link to the GPS data. This means that data on the link is going to get updated in next few hours and are going to look different from what I have written about them now.]
The eruption in Holuhraun continues as before. There has not been any view of the eruption for the past two days due to fog. So I don’t know for sure what is happening there.

Harmonic tremor data

I can see two things in the harmonic tremor data. The pressure is increasing in Bárðarbunga volcano system. I am also seeing pulses of harmonic tremor and that is not good. It means that magma has somewhere found a path to the surface, it just isn’t there yet, but it is working way up. It is impossible to know if this magma gets all the way up or not. Small eruptions are also not impossible, since there signature might simply be lost in the noise on the tremor plots that I am using from Icelandic Met Office.

Current status on the cauldrons

According to the news that I have heard some of the cauldrons that are in Dyngjujökull (south of Holuhraun) are still getting deeper. This suggest that there is still a lot of warm under the glacier that is melting the glacier. No glacier flood has happened due this. I don’t know if any new cauldrons have formed in recent days. Most of the cauldrons are located above the dyke, few are located above Bárðarbunga volcan in its slopes.

Tungafellsjökull volcano

I am seeing in the GPS data that Tungafellsjökull volcano might be getting more magma inflow. Since it appears to be inflating. This has not been confirmed so far. Currently there is nothing to suggest that Tungafellsjökull volcano is going to erupt at this point in time. It might simply be responding to the all the noise that Bárðarbunga is making at the moment, along with stress changes in the crust. If it erupts, it would be first documented eruption in the past 8000 years at least (maybe longer).

Next update is going to be tomorrow or sooner if anything major happens. It is possible to watch my webicorders here. They are updated every 5 min.

Bárðarbunga volcano daily update 17-September-2014

This information is going to go outdated quickly.

Current status in Bárðarbunga volcano at 16:36 UTC

The largest earthquake in past 24 hours took place yesterday (16-September-2014) at 21:34 UTC. It had the magnitude of 5,4. The largest earthquake today had the magnitude of 3,3 so far. This might change without warning.
Lava continues to flow out of the main crater in Holuhraun. The eruption is diminishing for the moment. That might change without warning if an new fissure opens up in the current eruption area, or in the glacier south of it. River of lava has been observed from the main erupting crater. Smaller craters that have stopped erupting are just emitting gas, two of three of the craters that have stopped erupting have lava lake in them at present time (latest report).
GPS data over the past few days suggest that magma flow into Bárðarbunga volcano is changing. I don’t think this is a good news. At the moment it is unclear what this means for current eruption and what is happening in the volcano.
Bárðarbunga volcano caldera continues to drop around 50cm/day at current rate. That is slightly slower than when it was dropping at the rate of 90cm/day about week ago.
Risk of eruptions under the glacier remains high and it is highly likely that eruptions might have happened under the glacier without anyone noticing them on the surface.
No major changes have taken place in glacier rivers that come from Bárðarbunga volcano area. Both when it comes to conductivity of water in the glacier rivers and amount of water in them.
There is currently no visibility to the eruption in Holuhraun due to thick fog in the area. I don’t know when the weather is going to clear up.
More magma continues to flow into the dyke than is erupting from it according to latests observations. This increases the risk of new eruption taking place along the dyke without warning.

Progress of the current activity

The eruption is happening in two parts in my view. The first part is the rifting episode that has now started in Bárðarbunga volcano fissure swarm. The rifting is going to happen in jumps with quiet period between them and the crust is going to crack or open up when that happens. This rifting has started in the northern part of Bárðarbunga fissure system. It has not yet started in the south part of the fissure, where features like Tröllagígar are (Tröllagíar crater row) exist. They erupted in the years 1862 – 1864. That magma that came up there closely resembles the magma that is now erupting in Holuhraun.

The second event that is happening is the collapse of Bárðarbunga volcano caldera. I now think that is an separate event in it self. Something must have happened in the volcano during past period of activity in 19th century that started this collapse, even if it did not start full force until current eruption episode. The caldera collapse is not going to stop the rifting process, that is going to run it course of the next few years (3 – 5 years is my best estimate now). This collapse is however going to make bad situation worse since when the collapse happens it is going to be a major problem for the local area. Since the area south of Bárðarbunga also has several hydro-dams that are in risk of some major damage, not just from fissure eruptions but also from glacier floods when they happen. In glacier floods triggered by eruption contain a lot more than just water. Glacier floods contains fragment of the glacier, many up to several meters high (20 – 60 meters high should be expected), mud, glacier clay, rocks, volcano material of all types, gases and several other things that I don’t know what are.

Current status at 18:45 UTC.

Bárðarbunga volcano has dropped 25 meters according to measurements taking today by University of Iceland and Icelandic Met Office. The speed of the drop in Bárðarbunga volcano caldera has slowed down from what it was about a week ago.
Currently the dyke from Bárðarbunga volcano is not expanding. Scientists are also not sure now how much lava has erupted at current time.

Current status at 23:56 UTC

There seems to be quiet period in the rifting episode at the moment. Along with general quiet period in Bárðarbunga volcano. It does not mean this is over, the eruption in Holuhraun continues and I continue to see harmonic tremor spikes taking place. I don’t know what the harmonic tremor spikes mean yet.
Largest earthquakes now have the magnitude of 4,1 (at 22:51 UTC) and magnitude 3,2 earthquake at 22:28 UTC.

Daily update on Bárðarbunga volcano, 15-September-2014

This information is going to get outdated quickly.

Current status at 12:59 UTC

Largest earthquake so far is a magnitude 5,4 that took place at 08:04 UTC.
Caldera has so far dropped 45 cm of today. Largest drop took place during the magnitude 5,4 earthquake and that lowering continued for two to three hours after the earthquake.
Eruption in Holuhraun continues at similar rate as yesterday (14-September-2014). Now it is mostly one crater that is erupting. The flow of lava is also not powerful enough to cross the river. So now it is spreading out from the central crater in all directions.
Earthquake activity has been moving south along the dyke. This means there is higher risk for earthquake eruptions under the glacier. There have been several minor eruptions under the glacier already.

Current status at 20:51 UTC

New vent has opened up south of current eruption. I can’t tell from Míla web cameras if this is a new vent or just old vent getting active again.
Most of the eruption continues in the central crater at the moment.
The rifting phase of the activity in Bárðarbunga volcano is going to take months to finish. In that time there are going to be more earthquakes and more fissure eruptions. There is also high risk of new dyke intrusions going into other directions from Bárðarbunga volcano.
If the Holuhraun eruption ends, a new one is going to start soon after in different place of that dyke. It might be on glacier free area or under the glacier. There is no way of knowing that for sure.

What to expect from Bárðarbunga volcano

I am writing this now, since I might not have time to do so on Monday. Updates are going to continue to go here until Monday. Unless something major happens.

The collapse of Bárðarbunga volcano

The collapse of Bárðarbunga volcano has already started. The caldera collapse in Bárðarbunga volcano started on 16-August-2014 and has been going on since then. Here is what I am expecting from the caldera collapse once it reaches its peak.

There are going to be earthquakes in the range of 5,5 and up to 6,7. Maybe larger if the crust can handle it.
Glacier flood are going to go south-west and north (Húsavík area) and possibly in other directions. I am expecting damage to hydrothermal plants in the pathway of the floods. How much damage there is going to be depends on the magnitude of the flood and the path it takes.
I am expecting long periods of no power in parts of Iceland once the flood has passed. I am also expecting lack of communications in large areas of Iceland. This is why Rúv has been telling people to get long-wave radios for the past few days. Usage of mobile network is also going to be unreliable in large parts of Iceland once the collapse starts full force in Bárðarbunga volcano. Due to damage that glacier floods are going to create.
I am expecting an ash cloud that might go up to 20 km or higher up in the atmosphere. It is however impossible to know for sure what happens until this starts.
It is difficult to know fore sure how much drop is going to take place, but it can be up to many hundreds of meters.
I fear that north slope of Bárðarbunga might collapse forward once this starts. Earthquakes in the area give clues about weakness forming there.

Bárðarbunga volcano is 2009 meters high above the ocean. This means there is a lot of material that is going to blow outwards once the collapse starts full force. This is might be one of largest eruptions in Iceland since it got populated more than one thousands years ago. I am hoping that the picture that I am drawing up is not as bad the reality once this starts. I am also hoping that no loss of life is going to happen. I am hoping for the best in this case, but the clues that I am getting are no good at all.

Current status on Bárðarbunga volcano at 19:30 UTC

This information is going to get outdated quickly.

Current status on Bárðarbunga volcano

There are now two lava lakes (at least) in the fissure that has been erupting in Holuhraun. The eruption has not yet stopped, but it is less powerful but the flow of magma from the craters has not slowed down based on latest observations.
Bárðarbunga caldera is getting lower by 80 cm/day according to GPS measurements and other measurements that have been made. Total drop in the caldera so far is 21 meter. Cracks have started to form in the glacier that fills the caldera. Normally there are no cracks in that glacier. Most of the cracks are in the central caldera.
More magma is flowing into the dyke than out of it. Eruption has not yet increased yet, this also increases the risk of new eruptions along the dyke.
The central crater in the eruption continues to erupt, other craters have mostly stopped erupting and several of them are just emitting gas now.
Largest earthquake since midnight was a magnitude 4,7 at 09:32 UTC.
The lava field continues to flow into Jökulsá á Fjöllum glacier river. It is slowly blocking it, some explosions might take place, but due to the thickness of the lava that does not seem to happen often.
SO2 pollution is a big problem now in parts of East Iceland. The pollution goes depending on wind, so for the moment it is East Iceland that is having this issue.
GPS data shows that inflation continues in the dyke. This is because more magma is flowing into it than erupting from as I did mention above.

Icelandic Government preparing for major eruption

It seems that Icelandic government has started to prepare for major eruption in Iceland. This is evident when they put up a banner like this on Rúv website.

Rúv radio blackout alert banner due to an eruption at the bottom of this image. Screen-shot of Rúv.is website.

When the national radio of Iceland sets up a image like that. I take it as they know that things are bad in Bárðarbunga volcano. Same way as I know it. The website in question that the banner connects to can be found here, it has English text.

Updates 12-September-2014

The amount of SO2 in Reyðarfirði has now around 4000 µg/m³ (at 22:45 UTC). People in that village and nearby area advised to stay indoors and don’t go outside.
The largest crater in Holuhraun is now getting close to being 70 meters high.

Updates 13-September-2014

Largest earthquake since midnight was a magnitude 4,9 earthquake at 07:58 UTC. At that same time the caldera dropped 25 cm according to news on Rúv.
GPS stations show fast movements around Bárðarbunga volcano. This means the current activity is far from over, even there has been a minor drop in activity at the moment.
Instability in Bárðarbunga volcano continues to increase.
There appears to be a fast inflation in Grímsfjall volcano. It is unclear why this is happening, but it might be due to influence from Bárðarbunga volcano. The sudden inflation in Grímsfjall volcano appears clearly on GPS measurement that are being done on top of the volcano. This might not lead to an eruption, since Grímsfjall volcano can take a lot of magma into its system. The eruption that took place in 2011 was the largest one in at least 140 years. Turns out this was just snow on the GPS antenna. So this is false alarm when it comes to Grímsfjall volcano.
Dangerous levels of SO2 are problem in eastern Iceland and where the wind blows it. Gas at the eruption site is also huge risk to anyone working in close proximity to the eruption site. It is also blocking the view to the eruption at Míla cams, along with dust storm that appears to be taking place now due to wind.
The eruption at Holuhraun is about the same as yesterday (12-September-2014).
The eruption is now confined mostly to the main crater in the fissure. Other craters have stopped erupting currently. That might change without warning.

Updates 14-September-2014

The eruption in Holuhraun seems to be ending. During the day the power of the eruption has dropped. The largest central crater is still erupting, but at a lot less power than yesterday and on 12-September-2014. Eruption has stopped in smaller craters in the eruption fissure.
The lava has stopped moving forward into Jökulsá á Fjöllum. It no longer has the energy to progress into the glacier river. New fields of lava are forming closer to the crater that continues to erupt.
Largest earthquake today (when this is written) is a magnitude 5,3 earthquake that took place at 14:06 UTC. Second largest earthquake today was a magnitude 4,0 earthquake that took place at 06:54 UTC.
The caldera continues to drop. Since this activity has continued to total drop is now 23 meters according to latest measurements (from yesterday). Most drop is taking place in north-east part of the caldera. More information can be found here, text is in Icelandic.
Harmonic tremor suggest that the pressure is increasing in Bárðarbunga volcano again. There is also high chance of small eruptions taking place under the glacier.
There is no rapid inflation taking place in Grímsfjall volcano. GPS signal got distorted by snow or ice on the GPS antenna.

Update on Bárðarbunga eruption at 17:32 UTC

This information is going to get outdated quickly.

A short notice: While I know a lot about volcanoes, earthquakes and such things. I do not know everything. I have read many science papers on the subject. But I have not read them all and I never will. What is also important is that nobody knows for sure what is going on in Bárðarbunga volcano. This is the first eruption in the volcano since recording of earthquakes started in Iceland and it appears that this eruption in Bárðarbunga volcano might be a big one (even if it not at that stage yet).

Update on the activity in Bárðarbunga volcano

Earthquake activity continues in Bárðarbunga volcano. The largest earthquake since midnight had the magnitude of 5,2 according to Icelandic Met Office.
Earthquake activity continues in the dyke south of the eruption area. This suggest that the dyke is still expanding in the crust.
Minor eruptions have taken place south of the main eruption in Holuhraun. Most of this are like the minor eruption that started south of the main eruption, but in glacier free area. Other minor eruptions that have taken place are under the glacier. They have formed small cauldron in the process without making a glacier flood.
Cauldron in the glacier have been spotted at 2 km inside the glacier (I think this distance is correct. If it is not. I will correct it), 6 km from the edge of the glacier and 10 km from the edge of the glacier. This cauldron are directly above the dyke and as mentioned above are the results of minor eruption taking place under the glacier. One of this cauldron was discovered on Friday. I don’t remember if it was included in the news that day.
There are no signs of the eruption in Holuhraun is about to end. The lava field is now creating a dam as it goes over the Jökulsá á Fjöllum glacier river path. This has created minor explosions in the past few hours and in process throwing up minor volcano ash at the same time.
There is still a lot of gas in the lava coming from the eruption. Making it extremely dangerous to go close to eruption and the lava field. This gas is in so high consternation that geologist working in the field are often at great risk.
Smell of sulphur (SO2) has now been found in parts of Norway according to the news (in Icelandic, Norwegian, map in the news from Norway). It is far from being on dangerous levels in Norway due to distance travelled.
The lava field continues to create its own local weather. Small tornadoes can be spotted on the Míla web-camera. There is also a lot of local cloud formations taking place. Sometimes limiting the view to the erupting area.
There is high risk of new eruption fissures opening up without warning.
Eruption activity in the main crater now happens in pulses according to latest news. It drops for a while and then goes high up. I think there is a reason for this behaviour.
It appears that the erupting crater are being closed slowly by there own erupting material. That might explain the pulsing behaviour that is now being observed from it. This also means there is enough pressure in the dyke to continue the eruption for a good while longer (in my view).
Inflow of magma and outflow of magma appears to be in balance for the time being. That balance might change without warning if something changes in Bárðarbunga volcano.

No confirmation on the eruption last night

So far there has not been any confirmation on the possible eruption that I did write about last night. This might not have been an eruption or there might not be any evidence of it on the surface of Vatnajökull glacier.

More notes on comments

Please do not post all your text in caps lock. It is rude to everyone else reading the comments on this website. I also want to point out that not everything is known as I noted above. Some questions do not have any answers yet when it comes to volcanoes or earthquakes, but there are no stupid questions far as I am concerned. I offer no guarantee on the answers however.

I also ask people just to be nice to each other here. I also have to ask you to provide links when text is posted here, it is both good for everyone who want to read more from that website in question. There also a requirement on doing so from Icelandic Met Office and University of Iceland in the disclaimers they have.

Rift valley has formed south of the eruption in Holuhraun lava field

This information is going to get outdated quickly. This is current events in Báðarbunga volcano.

Rift valley has formed south of the eruption. Part of this rift valley is not under the glacier. Most of this rift valley is under the glacier, were the glacier is thin the glacier has formed a cauldron that is around 1 km wide and several meters deep. There is a risk of eruption in the newly formed rift valley.
Harmonic tremor suggest that an glacier flood is under way from Bárðarbunga volcano. What is happening is unclear at the moment. Scientists and press people have been told to evacuate the area due to this risk.
More magma is going into the dyke then is erupting from it. This has increased the pressure inside the dyke.
Largest earthquake since midnight had the magnitude 5,5.

Updates

There has not been any sign of an eruption under the glacier yet. One idea for this increase in harmonic tremor is that ground water got into contact with the magma at 1 to 2 km depth.
There is a high risk of eruption taking place under the glacier in the area of Dyngjujökull glacier, that glacier is south of current eruption and can be seen on the Míla web cameras.
There is a lot of cracks in the ground south of the eruption, in some places the ground has dropped some meters down.

Updates on 4-September-2014

Largest earthquakes since midnight (04-September-2014) had the magnitude of 4,8 and 4,4.
The eruption is now creating 120 to 130 meters tall lava fountains at the moment. No other change has been reported.

Update on earthquake swarm in Herðubreiðartögl on 9-May-2014

This is a short update for the earthquake swarm in Herðubreiðartögl on the 9-May-2014.

For the past 24 hours there has been drop in activity and no earthquake has been over magnitude 2,0. Activity continues but a lot lower levels then before. It does not look like it is over at this point, but the end of this soon to be seven day earthquake swarm in this area.

The earthquake swarm in Herðubreiðartögl as it was today. It can be seen that earthquake activity was at lot lower levels today then yesterday (08-May-2014) or the days before that. Copyright of this image belongs to Icelandic Meteorological Office.

This can also be seen in the tracer on Icelandic Meteorological Office website. Copyright of this image belongs to Icelandic Meteorological Office.

This drop in activity can also be seen in drop in the harmonic tremor plots in Askja. Fewer earthquakes means less earthquake related noise on the harmonic tremor plot (2-4Hz blue line). Not all of the activity that appears here is from Herðubreiðartögl, some of it is from SISZ and Reykjanes ridge activity. Copyright of this image belongs to Icelandic Meteorological Office.

The drumplot from Icelandic Meteorological Office also show this drop in activity. Some of the activity that appears is from Reykjanes Ridge. Copyright of this image belongs to Icelandic Meteorological Office.

None of this earthquake activity is strong enough to appear on my geophones. Since earthquakes at Herðubreiðartögl need to be at least magnitude 3,0 or larger to appear clearly on my geophones. My webicorders website can be found here, it shows all earthquakes that are taking place in Iceland and are large enough to appear on it. Its mostly earthquakes larger then magnitude 3,0 that are currently taking place (when this written).

Interesting earthquake activity in Hamarinn volcano

Over the past few days interesting earthquake activity has been taking place in Hamarinn volcano. The earthquakes have been aligning along two east-west lines. Possibly an fissure in the volcano. I am not sure why this is happening, but I did record one earthquake from Hamarinn volcano today (07-September-2013) and that trace suggests this earthquakes have there origin in magma movements in the Hamarinn volcano. That has not yet been confirmed and this might never be confirmed due to lack of data. Largest earthquake so far had the magnitude of 2.2 at the depth of 4.5 km.

Hamarinn volcano earthquake activity. Copyright of this image belongs to Icelandic Meteorological Office.

Last eruption in Hamarinn volcano was on 11 – 12-July-2011. It was an minor eruption and I did cover it here and here. Small eruptions are common in Icelandic volcanoes just as the are in other volcanoes around the world. Before the minor eruption in the year 2011 there was several months of earthquake activity in Hamarinn volcano. The area that now has this earthquake activity is the same area that had this minor eruption in the year 2011. I do not know if current activity is an early indicator that it is going to happen again. It however cannot be ruled out currently. What can be done is to monitor current levels of activity and just wait and see what happens next.

Pictures of a old volcano rift zone

Here is a picture of what remains of Snæfellsnes – Húnaþing Rift zone. But this rift zone was activity about 4 million years ago. I do not know why this part of the rift zone is visible. But it seems to have escaped glacier erosion during past 4 million years since it became extinct.

The visible part of the Snæfellsnes – Húnaþing rift zone that was active about 4 million years ago. The farm in this picture is called Bjarghús. This picture is released under Creative Common Licence. Jón Frímann Jónsson took this picture on 24.03.2012.

This is where the visible rift zone disappear back into the ground. Its visibility resumes at distance. This picture is released under Creative Common Licence. Jón Frímann Jónsson took this picture on 24.03.2012.

The Snæfellsnes – Húnaþing rift zone is number two on this picture. What can be seen above ground is just a small part of it. This picture has been released under public domain licence. See this web page here for more details. This picture is not 100% correct on the details on the rift zones in Iceland. But is a good start for it.

Older blog post about this area can be found here. I am not expecting any eruption in this area. But it is always a possibly of a volcanic cone popping up in area like this. As the closest volcanoes to this area are only at the distance of 80 to 90 km south of it. But that is the Langjökull volcano, in the north part of it.
