Ash from Iceland's Grimsvotn volcano eruption has formed a sheet over icebergs in the glacier lagoon at the base of Vatnajokull, even though authorities said on Thursday that the eruption is producing mostly steam rather than ash.

While the volcano is said to calm down within a few days, national police said there will be no further disruption to flights in northern Europe.
