This is going to be a short update for Bárðarbunga volcano.
There are changes taking place in harmonic tremor on the SIL stations closest to the eruption in Holuhraun. I don’t know what this means exactly, the best idea at the moment is that the eruption is either ending or getting less in power. It is hard to know for sure at this moment due to the bad weather in Iceland. This might also just be part of normal fluctuation of the eruption.
Earthquake activity in Bárðarbunga volcano is the same now as it has been for the past few days.
Currently there are only 11 earthquakes larger then magnitude 3,0 in Bárðarbunga volcano for the past 48 hours. That is among the lowest number of earthquakes since this activity started in August-2014. Total of 117 earthquakes are on this map, that is now considered as “few” earthquakes compared to what was happening from August-2014. Holuhraun lava field is now 1,15 km³ in size, it also covers ~83,11 km². It is about the same size as Þingvallavatn lake. It is only going to take few more days until it is larger then largest lake in Iceland.
Please note that there is going to be bad weather in Iceland until Friday to Sunday. I am not sure when there is going to be break in the bad weather. Observations of what is happening in Bárðarbunga volcano are going to be difficult at best during this stormy days.
