Volcanic unrest under the Reykjanes peninsula has reduced somewhat overnight, though the level of seismic activity remains high. The risk of an eruption has neither increased nor decreased, according to one expert. The biggest earthquake last night was Magnitude 4.1 and occurred just before 01.00.

The volcanic instability that began yesterday at 14.20 has been calming down throughout the night, according to Met Office natural disasters expert Elísabet Pálmadóttir.

“The pulse of instability yesterday was a sign that magma was on the move but now we aren’t seeing that instability, which means that the magma is maybe not moving—but there is still seismic activity and we are on high alert from yesterday. We needed to react quickly there yesterday and we are monitoring extremely closely now,” Elísabet said on RÚV radio this morning. 

New satellite images were taken of the area yesterday evening and results of their analysis are expected around midday, in time for the scientific council meeting at 13.00. They are expected to give an even clearer picture of what is going on beneath the surface. 

After a quieter period in the night, seismic activity levels rose again after 06.00 this morning. Bjarki Kaldalón Friis, Met Office natural disasters specialist, says the earthquakes have moved slightly south, to Fagradalsfjall, and that it is too early to say if this means anything more significant. He says the overall risk of an eruption has neither increased nor decreased overnight. 

Do you have any questions about the earthquakes or volcanic activity?
