REYKJAVIK, Iceland – Iceland's authorities have raised the aviation warning code for a region close to the subglacial Bardarbunga volcano after a small fissure eruption in the area.
The country's meteorological agency described the eruption in the Holuhraun lava field, about five kilometers (three miles) north of the vast Dyngjujoekull glacier, as a "very calm lava eruption and can hardly be seen on seismometers."
Sunday morning's eruption was the third eruption in the area since Aug. 23. On Friday, a smaller eruption also prompted authorities to briefly raise the aviation warning code to restrict flights around the eruption site.
The Civil Protection Department said all airports remained open.
