Reykjavik, Iceland • Iceland lowered its aviation alert level to orange from red Sunday, saying there was no sign of an imminent eruption at the Bardarbunga volcano. And scientists at the Icelandic Meteorological Office said their announcement Saturday that the volcano had experienced a subglacial eruption was wrong.
But the office cautioned in a statement that seismic activity at the volcano, which has been hit by thousands of earthquakes over the past week, was not slowing, and an eruption remained a possibility in coming days.
Two earthquakes measuring over 5 in magnitude — the biggest yet — shook the volcano beneath Iceland's vast Vatnajokull glacier early Sunday. The Met Office recorded earthquakes of 5.3 and 5.1 in the early hours.
