Verder rommelt het rustig verder:quote:Update
• 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.

Wat ik niet terug vind is de SO2 uitstoot.quote:• Insubstantial changes have been in the volcanic eruption in Holuhraun over the last few weeks. The lava is now also flowing towards east northeast into the small island in the centre of the lava field. This change can be seen from web cameras.
• 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 Bįršarbunga 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.
