Bárdarbunga Volcanic System eruption


Olgeir Sigmarsson collecting gas samples during the flood basalt eruption at Holuhraun (Bárdarbunga Volcanic System, Iceland) on October 2, 2014. The average gas flux during the first three months of Bárdarbunga eruption was 1200 kg/sec of SO₂, which is seven times more than at Hawaii.
