Lightning streaks across the sky as lava flows from a volcano in Eyjafjallajokul

Lightning streaks across the sky as lava flows from a volcano in Eyjafjallajokul April 17, 2010. An Icelandic volcano that is spewing ash into the air and wreaking havoc on flights across Europe appeared to be easing up on Saturday but could continue to erupt for days or even months to come, officials said.

The Icelandic volcano which grounded air traffic over Europe is still erupting, but it is spewing less ash, the meteorological office and experts said on Wednesday. Close monitoring of the neighbouring and potentially more dangerous Katla volcano was also taking place, but there have been no signs it has re-awakened, they added.
