quote:

• The volcanic eruption in Holuhraun continues with similar intensity. Lava continues to flow out of the lava lake in the crater. The lava field continues to grow to the south. Yesterday a helicopter from the Icelandic Cost Guard used to examine conditions by the southern edge of the lava field, were lave is flowing on a 3-5 km wide area.
• Seismic activity in Bardarbunga continues to be strong. The biggest earthquake that was detected over the last two days was on Monday, 10. November at 22:39 of magnitude M5,2. In total 15 earthquakes between M4,0 and M5,0 were detected over the period. From noon on Monday the total number of earthquakes was around 130.
• Very few smaller earthquakes were detected in the dyke and at the eruption site in Holuhraun.
• An earthquake swarm was detected in Tungnafellsjokll glacier yesterday. The biggest earthquake was at 10:07 of magnitude M2,8.
• The subsidence of the Bardarbunga caldera continues with similar rate as last few weeks. Yesterday the GPS station was lifted out of the snow, which is now falling on the glacier. The sharp rise seen on the graph on the Icelandic Met Office web page, is the result of this operation.

• The volcanic eruption in Holuhraun continues with similar intensity as it has for the last two weeks. Lavacontinues to flow out of the lava lake in the crater to east southeast. Convection of sulphuric dioxide from the crater appears to be constant.
• Seismic activity in Bardarbunga continues to be strong but number of earthquakes stronger then M5,0 seem to be decreasing. The biggest earthquakes that were detected over the last two days were yesterday, 13. November at 20:46 of magnitude M4,9 and at 23:08 of magnitude M4,8. In total 17 earthquakes bigger then M4,0 were detected over the period but no earthquake stronger then M5,0 has been detected for four days. From noon on Wednesday the total number of earthquakes in Bardarbunga was around 140.
• About 25 smaller earthquakes were detected in the dyke and at the eruption site in Holuhraun. All of them under magnitude M1,5.
• The subsidence of the Bardarbunga caldera continues with similar rate as last few weeks although the rate of the depression appears to be slower.
• GPS measurements outside of Bardarbunga show that the displacement is slowing down.

• The volcanic eruption in Holuhraun continues with similar intensity as it has for the last two weeks. Lava continues to flow out of the lava lake in the crater to east southeast. The Lava field is now about 72 square kilometres.
• Seismic activity in Bardarbunga continues to be strong. The two biggest earthquakes that were detected since noon on Friday were both of magnitude M5,4. On Friday, 14. November at 11:25 and on Sunday, 16. November, at 01:37. In total 16 earthquakes bigger then M4,0 were detected over the period and 25 earthquakes between M3,0-3,9. In total 160 of earthquakes were detected in Bardarbunga since noon on Friday.
• About 50 smaller earthquakes were detected in the dyke and at the eruption site in Holuhraun. All of them under magnitude M1,6.
• The subsidence of the Bardarbunga caldera continues with similar rate as last few weeks. The rate of the depression in the centre of the caldera is decreasing but the flow of magma underneath the caldera is not decreasing since the depression area in the caldera continues to enlarge with the same rate as it has for the last three months.
• GPS measurements outside of Bardarbunga show that the displacement is slowing down.

Notes
• The volcanic eruption in Holuhraun continues to be strong. The activity is similar as it has been for the last two weeks but the lava flow is more fluctuating. The lava flow forms an extrusion to the east southeast. From midSeptember the productivity of the eruption has decreased.
• 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.
