Less ash was being produced by an erupting volcano in Iceland that has disrupted air traffic in Europe since last week, Icelandic experts tracking the volanco said Tuesday, DPA reported.
The volcano, located about 120 kilometres east of the Icelandic capital of Reykjavik, near the Eyjafjallajoekull glacier, erupted last week.
Red-hot molten lava splatter was spotted overnight, suggesting that less ash was being produced, meteorologist Arni Sigurdsson said.
Although less ash was being produced, Sigurdsson said "some ash is still being carried up" into the atmosphere.
"We don't know what the limit for allowing air traffic should be," he added.
Winds were forecast to shift from a northerly to a more southerly direction during the day, and might affect the height of the plume, which could rise to some 4.5 kilometres.
Ash was still being deposited locally near the volcano.
