An earthquake of magnitude 5.0 shook Bárðarbunga at 5:40 this morning. It was in the same vicinity as other big quakes have occurred in the past few days.
The stars show earthquakes of magnitude over 3.0. These are the earthquakes which have hit in the past 48 hours. The new fissure is between Holuhraun and Dyngjujökull glacier.
Increased seismic activity began in the area on August 16 with a minor sub-glacial eruption occurring in the Bárðarbunga volcano on August 23. It did not manage to penetrate the 400 to 600 meter (1.300 to 2.000 feet) thick ice.
Since August 31 the fissure eruption in Holuhraun has been continuous, and yesterday a new fissure opened between Holuhraun and Dyngjujökull. This raises concern over the possibility that the eruption moves under the glacier with a risk of flooding, but so far there is no sign of that.
There is no danger to people or animals outside the eruption area, which is quite remote.
