restless Bardarbunga volcano to red, indicating that some type of an
eruption is imminent or in progress.
Thousands of small earthquakes have rattled the volcano deep
beneath Iceland’s Vatnajokull glacier in the last week, with activity
picking up Saturday after a lull the day before.
The eruption of Iceland’s Eyjafjallajokul volcano in 2010
produced an ash cloud that caused international aviation chaos, with
more than 100,000 flights cancelled.
