During the night of 27-August-2017 two strong earthquakes took place in Bárðarbunga volcano. The two earthquakes had magnitude 3,8 at 01:42 UTC and magnitude 4,2 at 01:45 UTC. The second earthquake is the largest earthquake to happen since 02-August-2017 when a magnitude 4,5 earthquake took place.

Over the past few months there has been a considerable decrease in earthquakes happening in Bárðarbunga volcano. Now earthquakes don’t appear weekly or every 14 days as was the case for a long time. Now a strong earthquake with magnitude above 3,5 or above 4,0 happens once a month or twice a month as is the case for August-2017. This brings up the question of Bárðarbunga volcano is getting close to being fully inflated again since the eruption in Holuhraun ended in February-2015.

Thanks Jon, is it time to be watching Bardarbunga more closely ? and whats with the 2.7 at 90.12% is it part of this activity just not verified or will it be dropped from the list?
The magnitude 2,7 is just a leftover from the automatic system.
Magnitude 2,7 -> 3,8 and magnitude 3,0 -> 4,2.
Isnt katla very quiet or is this normal?!
I assume there’s a strong Wind around the Aus stationa at the moment? Other than that all remains quiet. Hardly any EQ’s apart from the odd small ones seems to be occuring around Katla since last month
The wind in south Iceland is little at the moment. You can always check predicted wind conditions here.

Looks like Bardarbunga is doing a bit of shaking again.
It looks like something might be waking up in Vestmannaeyjar?
Rifting there as well? As there is rifting everywhere else…
Something is clearly going on (I think).
Off topic, but NASA are planning to inject water into magma under Yellowstone to prevent an eruption. Do they know what happens when you put water into magma?
