This update is going to be a short one. Since not much change has taken place in Bárðarbunga volcano since yesterday. Activity continued in Holuhraun same as yesterday, there was a new video of the erupting crater in ten clock news at Rúv. It showed the same lava lake that is now erupting and the lava river flowing from it. The video can be viewed here, it starts at 14:21.
Earthquake activity has been same as it has been for the past one month (about). Largest earthquakes had the magnitude of 4,8 and several magnitude 4,7 earthquakes took place. Other earthquakes have been smaller in magnitude. Harmonic tremor has been unstable, suggesting that minor eruptions might be taking place under the glacier. At least something is going on under the glacier, what exactly is not clear at the moment.
