Iceland's Eyjafjallajokull volcano, ash cloud from which paralysed much of Europe's air traffic for over a month, is showing a marked drop in activity, a volcanologist has said.
Video footage on Sunday indicated that the temperature in the crater had fallen to just 100 degree Celsius, leading volcanologist Magnus Gudmundsson said.
This means Eyjafjallajokull is now producing steam, not magma, Gudmundsson was quoted as saying by the BBC.
But the volcanologist warned it was too early to say whether the eruption was completely over.
"What I can confirm is that the activity of the crater has stopped. No magma is coming up," he said.
Iceland's meteorological office, meanwhile, said eruption activity was "minimal", and civil protection agency official Iris Marelsdottir said the volcano was "quiet".
The volcanic eruption began April 14, which disrupted air traffic over large parts of Europe for over a month.
