In July-2011 a minor eruption took place in Hamarinn volcano (part of Bárðarbunga volcano system). For a long time I’ve thought that those events in Hamarinn volcano where an eruption, rather than anything else. Due to how the glacier flood appeared and how sudden this all thing did happen.
Today (05-March-2016) Stöð 2 (Channel 2) ran a small news segment about this and the possible confirmation of this minor eruption in Hamarinn volcano in July-2011. I have the same view on the minor eruption in Katla volcano that same month. Its the view of Magnús Tumi, professor in geology that the events in Katla volcano where due to hydrothermal activity, not a minor eruption. I disagree with his assessment on what did happen in Katla volcano that summer. The top flood from Hamarinn volcano in July-2011 was 2.200m³/sec.

New harmonic tremor detected. But it is not from Katla volcano
Glacier flood confirmed from Vatnajökull glacier, flood is from Hamarinn volcano (Loki-Fögrufjöll area)

Thanks for this interesting info and the links, Jón.
I walked under Hamarinn in 2013 and noticed that there had been substantial changes to the landscape compared to even recent maps: Leynidalur had disappeared (there’s a bilingual pun there for Icelandophiles), and we camped in the middle of Hvítalón – or at least, that’s what our map said!
I’d wondered whether it was the rumoured eruption that might have caused these changes, to it’s good to have this report.
