Today (13-June-2017) a magnitude 2.6 earthquake took place in Öræfajökull volcano. This is the largest earthquake in this volcano for a long time now and it is worth noting that Öræfajökull volcano normally doesn’t have any earthquake activity. This suggests that something might be up if it doesn’t start to quiet down in next few years. Earthquake activity in Öræfajökull volcano is not high as can be seen in this science paper that covers the years 1994 – 2007 in earthquake activity in Iceland.

Tectonic settings in this area don’t allow for a lot of crustal-tension earthquakes and that suggests that the source of current earthquake activity in Öræfajökull volcano can be explained by magma movements. If this is going to end in a eruption remains to be seen. At the moment current low level activity rules that out, since a lot more and stronger earthquake activity needs to happen before magma can reach the surface.

I wrote article about social media and how its getting useless.

These days one can’t say alot of things in case you might offend someone!
That is the risk, but as I say in the article. The people that don’t want democracy are getting good at exploiting the systems that are supposed to fight them (filters design to prevent abuse, hatred and so on). That’s not good.
A green star for Katla (MW E3.2) and 2 quakes both MW 2.8.
All 3 quakes had a depth of 0.0 meters and 99% quality.
Ice instability, normal activity.
No, this is unusually strong earthquake activity for Katla in June.
The Oraefajokull Volcano is on the other hand awakening.
Shallow seismic activity.
