The eruption appears to have ceased for now at the fissure which opened up in the Holuhraun lava field at 00.02 last night. By 02.40 am all activity seemed to have calmed down along the 1 km (0.6 mile) fissure. Below are two images of the new lava, taken by the Icelandic coast guard shortly before 11 am this morning.
Seismicity seems to have decreased slightly due to the release of pressure however there have still bee quite a few earthquakes between the site of the fissure and the approximately 5km in to the Dyngjujökul glacier.
All activity so far suggests an effusive basaltic eruption which mean the risk to aviation from ash clouds are remote.
