A burst of high-altitude ash from Eyjafjallajökull Volcano on May 4, 2010, led to another round of flight delays and cancellations in the British Isles.
Acquired May 13, 2010, this natural-color image of Eyjafjallajökull Volcano shows a puffball of volcanic ash towering over a lower-altitude ash plume that fans out toward the southeast.
This true-color image from July 27, 2009, shows a plume blowing toward the northwest from Batu Tara. The distinct segments of the plume suggest that it was released in pulses of volcanic activity.
