Uh oh. Hekla is the volcano indicated by the purple pin. Eyjafjallajökull is the red pin. Katla, the really scary one, is the big white splotch just to the east of the red pin.
UPDATE: It's apparently a false alarm. An Icelandic Broadcasting Service camera was pointed at Eyjafjallajökull but it was labeled Hekla. MSNBC picked up the breaking news item.
