The volcanic eruption in Holuhraun continues at similar rate, and has now been going on for more than 50 days.
Depth vs time of recent earthquakes under Bárdarbunga
The erupted lava flow volume approaches 1 cubic kilometers and the lava flows now cover over 63 square km.
A large lava lake above the central section of the fissure vent has formed and feeds a wide river of lava:

Seismic activity in Bardarbunga continues to be strong, and has somewhat increased over the past days. More than 50 quakes above magnitude 3 have occurred in the caldera during the past 2 days. At least 15 were larger than magnitude 4, the biggest being two 4.8 quakes at 13:21 on Wednesday and at 13:07 yesterday.
At the dyke, smaller earthquakes continue as well at reduced rate.
Subsidence of the Bardarbunga caldera continues at remarkably steady linear pace of approx. 50 cm per day.
No other significant changes have been detected.
