There are changes taking place in harmonic tremor on the SIL stations closest to the eruption in Holuhraun. I don’t know what this means exactly, the best idea at the moment is that the eruption is either ending or getting less in power. It is hard to know for sure at this moment due to the bad weather in Iceland. This might also just be part of normal fluctuation of the eruption.

quote:

• Insubstantial changes have been in the volcanic eruption in Holuhraun over the last few weeks. The eruption is now well visible on web cameras and the activity appears to be similar to preceding weeks.
• Seismic activity in Bardarbunga continues to be strong, but it has though somewhat decreased. Total number of earthquakes in Bardarbunga from the last meeting of the board, on the 6 of January, is just over 100. Just over 10 earthquakes were between M4,0-5,0. The strongest one was M5,1 yesterday, 8. December, at 18:47. Few earthquakes were detected in the dyke of the same period, all of them smaller then M2,0.
• GPS measurements near northern Vatnajokull glacier show continuing slow deflation towards Bardarbunga. The rate of the deflation continues to slow down.
• The GPS station in Bardarbunga caldera show that the caldera continues to subside. The rate of the subsidence continues to slow down and is now between 10-15 cm per day.

• Insubstantial changes have been in the volcanic eruption in Holuhraun over the last few weeks. Although the power of the eruption has diminished, it is still quite forceful. The flow of lava is now largely under the surface of solidified lava.
• Seismic activity in Bardarbunga continues to be strong, but it has though somewhat decreased. The largest earthquake since the last meeting of the Advisory Board was of magnitude M4,7 on Saturday, 10 of January at 18:23. In total 16 earthquakes were recorded of the period between magnitude M4,0-5,0 and 13 between M3,0- 4,0. Over 20 earthquakes were detected in the dyke of the same period, all of them smaller then M2,0.
• Six earthquakes were detected in Tungnafellsjokull glacier since Friday. The biggest was M2,1 tonight, January 13 at 04:21. Around 20 earthquakes were detected around Herdubreid, all smaller then M2,0.
• GPS measurements near northern Vatnajokull glacier show continuing slow deflation towards Bardarbunga.
• The GPS station in Bardarbunga caldera show that the caldera continues to subside.
• Indications are of increased respiratory symptoms in Iceland over the period of the volcanic eruption. No serious cases have though been reported.
• High values of sulphuric dioxide are still being recorded. Over the weekend high values were recorded in Hofn (3400 µ/m³) in Reydarfjordur (1000 µ/m³) and in Jokuldal (7800 µ/m³).

• Insubstantial changes have been in the volcanic eruption in Holuhraun over the last few weeks. Volume of the lava flow, over the last few weeks, is estimated 50-70 cubic meters per second.
• Seismic activity in Bardarbunga continues to be strong. Over the last few weeks it has though been quite weaker than in the first months of the event. Three earthquakes of magnitude M4,6 were detected since the last meeting of the Advisory Board on Tuesday, 13. January. Sixteen earthquakes were detected between magnitude M4,0-5,0 during that period and in total around 150 earthquakes were detected.
• Around 40 earthquakes were detected in the dyke during the same period, all of them smaller then M2,0.
• Around 20 earthquakes were detected in Tungnafellsjokull glacier since last Tuesday. The strongest one was M3,1 on January 13 at 13:17. Friday. Around 20 earthquakes were detected around Herdubreid, the strongest one was M2,3.
• GPS measurements near northern Vatnajokull glacier show continuing slow deflation towards Bardarbunga.
• The GPS station in Bardarbunga caldera is not transmitting any data at the moment. A repair mission is being organised to get the station back on-line.
• High values of sulphuric dioxide are still being recorded.
