Lava field now approx. 85 square km

The surface of the lava flow field is now approx. 85 square km. It continues to grow slowly mainly along its northern margin and at the eastern tip.
Eruption continues with little changes

Lava effusion continues at high rates and enlarges the lava field, now covering more than 84 square kilometers.
It has crossed the track Dyngjufjallaleið and stretched onto the older lava of Þorvaldshraun.
Lava is mainly flowing through a closed channel to the eastern edge of the lava field, about 15 km from the crater. Another tube system is transporting lava to the northern part.
Seismicity under the Bardarbunga central volcano's caldera remains strong. Subsidence of the caldera continues as well, at approx. 25 cm per day.
Eruption continues with little changes

The eruption at the Holuhraun fissure goes strong into the new year and might continue for a while. No significant changes have occurred recently.
The lava field is now well over 82 square km large, a mapping from 29 Dec. shows.
Seismic activity remains concentrated around the summit caldera of Bardarbunga central volcano, while it is very low beneath the erupting dyke - magma has an open conduit towards the surface.
Eruptino continues, but seismic activity decreases under caldera

The eruption continues, but seems to be becoming slowly weaker. The latest measurement shows the Nornahraun lava field measures now more than 81 square km.
Seismic activity under the caldera has been slowly decreasing overall as well.
However, the decreasing trend is very weak and the eruption could still continue for many months, or take a new, unexpected evolution at any time. The future, or probably 2015 will tell!

The eruption continues with little variation. The Nornahraun lava field is now almost 80 square km in size. An extensive lava tube system has formed inside it, bringing supply of lava to the outer areas.
Earthquake activity remains significant under the caldera, which continues to subside. Occasional quakes reach magnitudes above 5.
Lava field now more than 77 squake km, no end of eruption in sight

According to the latest measurements, the lava field from Holuhraun now covers 77,5 km². The eruption which had its 100th day on 9 Dec, continues with little changes and there is no end in sight.
Active breakouts are located on the northern margin of the lava field, now called "Nornahraun".
Earthquake activity under the central volcano remains elevated, but over the past weeks, earthquakes larger than magnitude 4 have become more rare. Recent geochemical studies of the lava show that it seems to rise directly from a source at 9-20 km depth, i.e. is generated by decompressing mantle material.
