Well, Iceland is at it again - this time Grimsvotn volcano under a bigger icecap than last year's Eyjafjallajokull eruption. So far , according to my friend in Iceland, the south east is covered in ash including Jokulsarlon - that ice lagoon is now just black topped. I wonder if air traffic will be affected again.

If anyone's interested - a web cam over the lagoon - usually its blue ice --- now with a black ash topping ...
