The Northern Lights are seen above the ash plume of Iceland's Eyjafjallajokull volcano on April 23. Iceland's volcanic eruption was spewing far less ash on Thursday and the plume of smoke was low, but a change of wind direction meant Iceland's airports were now set to close for the first time.
The Icelandic volcano ash cloud drifting over Northern Europe grounded hundreds of flights, frustrating travelers.
The Iceland eruption of the Grímsvötn volcano Saturday was far larger than than last year's Eyjafjallajökull eruption, but scientists say it is unlikely to disrupt Europe as much.
The volcanic ash cloud from Iceland dissipated today and a British Airways labor strike was canceled, allowing Europe's airports to return to near-normal operations. But the British Met Office is taking fire for its volcanic ash cloud forecasts.
