Update, September 14, 2015: Per this news report, magma may be accumulating again. Also, and I didn’t realize this,
The Holuhraun eruption is now seen as a chapter in a story that began in 1974.
So I’m changing the headline from “Bardarbunga eruption” to “Holuhraun eruption.” That eruption is over, but this volcano, Iceland’s largest, is still in an active phase. Of note, though, the Iceland Met Office does not have a hazard banner flying on their website.
Update, March 24, 2015, 4:17 p.m. Pacific: The research numbers are coming out. Gas pollution was reportedly the worst hazard from this eruption, particularly in Höfn, and it was the gassiest eruption in Iceland since the 18th century (probably they refer to Laki, which was WAY worse).
Update, March 11, 2015:This is one of the things I love about volcanoes – there are always updates. In Bardarbunga’s case, reportedly the caldera has started to rise again. It could mean ice is flowing into it, or it could mean that magma is building up again underneath. No eruption is imminent, but it’s interesting.

Per the scientists today:
The eruption in Holuhraun, which began 31 August 2014, has come to an END.
- The area continues to be closely monitored.
- Gas contamination is still detected around the eruption site.
- No changes have been made to the restricted area north of Vatnajökull.
- The Civil Protection still operates in alert phase.
- Aviation Colour Code for Bárðarbunga has been downgraded from orange to yellow.
Per the Icelandic Met Office, it’s going to get stinkier for a while:
28 February 2015 – gas emissions continue
In spite of relief at the end of the eruption in Holuhraun, conveying gratitude to staff and co-workers, the Icelandic Meteorlogical Office still monitors gas dispersal closely.
Other lava eruptions have taught that the lava field continues to emit gas for a long time yet and without the thermal rise from an open vent, the volcanic gases will tend to follow the ground. Therefore, even higher values of more polluting gas may be expected now than in recent weeks.
Here’s how it looked back in October:
