Power of eruption has decreased since Wednesday - Icelandic Met Officepublished at 11:38 British Summer Time 30 May
The power of the eruption has decreased significantly since it started on Wednesday.
"The most activity is now on a few vents, but due to the limited visibility in the area [it is wet and cloudy], it is difficult to say how many there are," the Icelandic Met Office said this morning.
Lava flow is greatest north of the fissure, and at the vent at S媒lingarfell which opened last night.
