The country’s meteorological agency described the eruption in the Holuhraun lava field, about 5 km north of the Dyngjujoekull glacier, as a “very calm lava eruption and can hardly be seen on seismometers.”
“Visual observation confirms it is calm, but continuous,” the weather agency said on its website.
Sunday morning’s eruption, which took place about 1 a.m. (EST), followed a smaller one in the same site on Friday that also prompted authorities to briefly raise the aviation warning code to restrict flights in the area.
