quote:• Insubstantial changes have been in the volcanic eruption in Holuhraun over the last few weeks. The lava field has thickened substantially but activity on the surface has decreased.
• The subsidence in Bardarbunga caldera was measured from air on Wednesday. The volume of the subsidence is now 1.7-1.8 km3. The change in volume from the last measurement corresponds to a flow of magma from underneath Bardarbunga of about 60 m3 per second. The greatest subsidence is now about 61 meters. Over the last few weeks the geothermal cauldrons in Bardarbunga have enlarged.
• 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. No earthquake over M5,0 has been detected in Bardarbunga for 15 days, which is the longest period between M5,0 earthquakes since the seismic activity started in August. The strongest earthquake since the last meeting of the Advisory Board on Tuesday was measured M4,7 yesterday at 03:07. Eight other earthquakes between magnitude M4,0-4,7 were detected over the period and about 37 earthquakes between M3,0-4,0. In total around 150 earthquakes have been detected around the caldera since last Tuesday.
• Around 65 earthquakes were detected in the dyke during the same period, the strongest one was measured M1,5.
• Insubstantial earthquake activity was detected in Tungnafellsjokull, Askja and Herdubreid.
• GPS measurements near northern Vatnajokull glacier show continuing slow deflation towards Bardarbunga.
• Around 2200 µg/m3 SO2 were recorded on Thursday in Reykjahlid and at lake Myvatn. Very high values of SO2, about 84000 µg/m3, were recorded at the eruption site in Holuhraun on Wednesday, being the highest values recorded at ground level since the eruption started.
quote:• The volcanic eruption in Holuhraun continues. Visible intensity of the eruption was low on last Wednesday while various observations were done at the eruption site. Comprehensive cross-section measurements from air (on 30. December and 21. January) show however that the lava field has thickened substantially during these three weeks and that the volume of the lava field is now little less than 1.4 km3. The flow of magma, during this period, was just under 100 m3 per second. The intensity of the eruption is there for slowly decreasing but hopefully it will be possible to measure the volume of the lava field again later this week, which will give new numbers on the flow of magma.
• Seismic activity in Bardarbunga continues to be strong. Eight earthquakes between M4.0-4.9 have been detected since the last meeting of the Advisory Board on Friday. The strongest one was measured M4.9 on Saturday, 24. January at 07:25. About 40 earthquakes between magnitudes M3.0-3.9 were detected over the period. In total around 150 earthquakes have been detected around the caldera since last Friday. No earthquake over M5,0 has been detected in Bardarbunga since 8. January.
• Around 50 earthquakes were detected in the dyke during the same period. Most of them were under M1.0 but the strongest one was M1.6 on 24. January.
• GPS measurements near northern Vatnajokull glacier show continuing slow deflation towards Bardarbunga.

De prijzen met een helicopter vanaf Reykjavik zijn abnormaal om het vanuit de lucht te zien.
Ik heb het in Hawaii al vanuit de lucht gezien, dus zie het niet als meerwaarde.

• Seismic activity in Bardarbunga continues to be strong. The strongest earthquake since the last meeting of the Advisory Board on Tuesday was measured M4.9 tonight at 03:48. Two other earthquakes stronger than M4,0 were detected since Tuesday, one was M4,5 and the other M4,0. About 10 earthquakes between magnitudes M3.0-3.9 were detected over the period. In total around 110 earthquakes were detected around the caldera since last Tuesday. No earthquake over M5,0 has been detected in Bardarbunga since 8. January.
• Around 20 earthquakes were detected in the dyke during the same period. The strongest one was M1.8.
• GPS measurements near northern Vatnajokull glacier show continuing slow deflation towards Bardarbunga.
• The highest levels of sulphuric dioxide since Tuesday, 3rd of February, 800 µg/m³ SO2 was measured in Vopnafjordur on Tuesday.
• A new risk analysis for the area around the eruption site is being conducted. The new risk map for the area will be issued next week.
• A team of technicians from The Icelandic Met Office, Institute of Earth Sciences UI, and The Department of Civil Protection have been working on maintenance on measuring equipment’s on Vatnajokull glacier and in the surrounding area. The GPS station in the Bardarbunga caldera is back on-line and will be visible on the IMO web site as before.

quote:Notes
• The volcanic eruption in Holuhraun continues, but it has diminished substantially over the last few weeks. Visual activity in the crater has decreased and the lava field is hardly increasing in size.
• Seismic activity in Bįršarbunga continues to diminish although it can still be considered strong. The strongest earthquake since Tuesday was measured M4.3 at 01:26 yesterday. Two other earthquakes stronger then magnitudes M3.0 were detected over the period. In total around 70 earthquakes were detected around the caldera since last Tuesday. No earthquake over M5.0 has been detected in Bįršarbunga since 8. January. A distinct pulse of earthquakes occurred yesterday between 01:25 and 02:10. Time intervals between such pulses have significantly increased from 2-4 hours in the beginning to 12-24 hours or more at the moment.
• Around 65 earthquakes were detected in the dyke during the same period. The strongest one was measured M1.6 today at 08:24 in Dyngjujökull glacier.
• The rate of the subsidence in Bįršarbunga caldera had decreased substantially. But that is not the whole story. Ice is subsiding into the caldera with the effect that the GPS station does not show any changes. The estimated depression of the rock foundation of the caldera, in the light of the ice subsidence, is about 5 cm per day. The flow of magma from under Bįršarbunga is believed to be 25-30 m3 per second, which is about one tenth of the flow in September last year.
• GPS measurements near Vatnajökull glacier show continuing slow deflation towards Bįršarbunga, indicating a flow of magma from under the volcano.
• About 7 earthquakes were detected around Askja and 15 around Heršubreiš since last Tuesday. All of them smaller than M1.5.
