The newest case involves a millionaire (or billionaire?) from Kazakhstan that landed close the lava field. They where lucky that wind did not change direction while they where there. The amount of SO2 close to the eruption has been recorded going up to 130.000 μg/m³. That is good enough to kill instantly and melt people lungs (read up on that can be found here).

IJsland enzoquote:15:00 Geen nieuwe feiten. Het GPS-apparaat in het midden van de caldera is op dit moment niet functioneel. Met hoopt deze storing snel op te lossen, omdat het de enige manier is om op de hoogte te blijven van de caldera-verzakking.
Een wetenschapper, genaamd Harald Siguršsson heeft berekend, dat deze uitbarsting in de huidige vorm door kan gaan tot begin maart volgend jaar.
Harald geeft zelf aan, dat gebruik gemaakt is van sterk vereenvoudigde rekenmodellen. De tijd zal leren, in hoeverre Harald gelijk heeft.

En de lang verwachte update:quote:12 October 2014 10:00 - from geoscientist on duty
The eruption: Webcameras show no significant changes in the eruption.
Earthquakes: Since 10:00 UTC yesterday (Saturday) two quakes over magnitude 5 occurred in Bįršarbunga. The first one M5.0 at 11:30 yesterday and M5.2 at 08:43 this morning. Both originated in the northern rim of the Bįršarbunga caldera. Additionally, four quakes over magnitude 4 were registered: Yesterday M4.7 at 19:33, M4.1 at 01:36 last night, M4.0 at 03:57 and M4.2 at 06:20. Over 100 quakes have been registered during past 24 hours in the caldera and about 25 in the northern part of the intrusion.
Gas pollution: Northeasterly winds are expected today (Sunday), so the pollution is expected towards south and southwest from the eruption. Polluted area is bounded by Faxaflói in the west and Mżrdalur in the east and is expected to extend north of Hofsjökull. Tomorrow (Monday) wind will be southerly and the pollution will go north.
The Icelandic Met Office provides two-day forecasts on gas dispersion from the eruptive site in Holuhraun. Most reliable are the forecast maps approved by meteorologist on duty. And although still being developed further, an automatic forecast (trial run, see disclaimer) is also available.
11 October 2014 10:00 - from geoscientist on duty
From now on a change is made in these reports from a geoscientist on duty, and they will be published daily at about 10:00 UTC. This may be changed if the eruption changes significantly.
The eruption continues with the same lava flow rate as in past weeks.
Seismicity is similar to previous days:
- There is low activity in the dyke intrusion. Around 20 earthquakes have occurred during the last 24 hours, all within magnitude 1.5 and in the northern part of the intrusion between the eruption site and to the south some kilometers under Dyngjujökull glacier.
- About 80 earthquakes were detected on the caldera rim of Bįršarbunga. The largest earthquakes were at 11:26 and 23:51 yesterday, both of magnitude 4.8. Earthquakes of magnitude 4.7 and 4.5 also occurred and seven between 3.0 and 3.9. Most activity was on the northern caldera rim.
Displacements (no significant changes):
- Minor movements of GPS stations in the area.
- Subsidence of the caldera continuing at similar rate.
Water monitoring: No changes.
Gas forecast (latest forecast 09:32 UTC): Today (Saturday) and tomorrow (Sunday): Northeasterly winds are expected with the possibility of gas pollution south and southwest of the eruption site in an area from Hellisheiši in the west to Hornafjöršur in the east.

10 October 2014 19:00 - from geoscientist on duty
Since midnight, no earthquakes above M5 have been detected in the caldera. The largest occurred during the night (4.7 in size) and half an hour before noon, M4.8. Quite a number of smaller quakes has been detected at the caldera (almost 60 since midnight, the majority at the northern rims). Also in the dike (about 20), from the eruptive site and to about 10 km within the Dyngjujökull margin.
An observation from a surveillance flight with TF-SIF today, revealed great blue mist and gas from the eruptive site to about 3 km height above the crater. From there, it is carried across the South Iceland lowland and across West Iceland as far as could be seen from the aircraft. The pollution seems to be greatest just west of Eyjafjallajökull but is also considerable towards Mżrdalssandur.

quote:16 October 2014 10:00 - from geoscientist on duty
During the last 24 hours, about 70 earthquakes have been detected at Bįršarbunga and a dozen in the northern part of the dike. This is somewhat less activity than 24 hours earlier. Two quakes over five in magnitude occurred at the northern caldera rim; an M5.4 at 11:16 yesterday and an M5.0 in the early hours of the morning, at 03:14 today. One earthquake M4.2 occurred later this morning, at 09:25, in a similar location.
Observations of deep thudding sounds were received yesterday while the large earthquake occurred, possibly as a consequence thereof. Scientist went to Askja yesterday but found no signs of a rockfall, which could have caused the noises. Possibly the sounds were from jet aircrafts, passing at the same time.
