Air travellers remain on alert for potential disruption this week despite the lowering of the threat level from an Icelandic volcano.
The Icelandic Met Office downgraded its aviation risk warning yesterday from red to orange after scientists monitored seismic activity around the Bardarbunga volcano.
It had issued the red warning after authorities detected signs of a small eruption beneath a glacier near the volcano in central Iceland. Closer analysis found that there had been no disruption, which led to the downgrading.
“Observations show that a sub-glacial eruption did not occur. The intense low-frequency seismic signal observed has therefore other explanations,”
