Today (21-September-2015) a minor (so far) earthquake swarm has been taking place on the Reykjanes ridge. Largest earthquake so far had the magnitude of 3,5 so far other earthquakes have been smaller in magnitude.

It is difficult to know for sure what happens. Earthquake swarms in this part of the Reykjanes ridge often end quietly, but they can also just pick up as easily, it is impossible to know for sure.
I don’t have the time or the energy to write a long article about what is going on in Bárðarbunga and Tungnafellsjökull volcanoes. What I do know is that magma appears to be pressuring Tungafellsjökull volcano, creating earthquakes, the largest earthquakes so far have reached magnitude 2,9. Other earthquakes have been smaller. Some of the earthquakes appear volcanic in nature based on what I’m seeing on my geophones (at poor resolution at the moment).
In Bárðarbunga volcano there has also been earthquake activity today. I don’t know yet if its due to inflation or deflation of the magma system in Bárðarbunga volcano. Largest earthquake today (21-September-2015) had the magnitude of 3,2. Other earthquakes have been smaller, this earthquake activity has been small so there is a chance this does not mean anything yet.

The activity in Tungnafellsjökull volcano is likely to continue and might increase. I’m not sure what happens in Bárðarbunga volcano at the moment.
Working schedule: In September and until end of October I’m working Monday to Friday from 07:00 – ?? (Monday/Wednesday/Friday) and 10:00 – ?? (Tuesday/Thursday). Due to the nature of the work (its a slaughterhouse work) I don’t have my mobile phones with me and therefor I don’t know what is going on if anything happens. The longest days are now in process and are going to last until second or third week of October I think.
