Yesterday (23-February-2019) a earthquake with the magnitude Mw 4,2 took place in Bárðarbunga volcano. This earthquake was in the north-east location of the caldera. This is the location were most earthquakes happen in Bárðarbunga volcano. There appears to have been a foreshock this time with a magnitude of 2,7.

I can’t provide wave image of the earthquake since my main earthquake computer is broken and I can’t afford for the moment getting a new one (+Windows 10 Pro licence). I hope to get a new computer this summer for this task along with switching to Raspberry Shake seismometer.
EMSC/USGS show the magnitude as 4,5 this happens due to difference method used for calculate the magnitude of this earthquake.
Update
I did manage to get the earthquake trace data from the remote station that handles it.

Windows 10 can still be used on a ‘trial’ basis if you run the following command:
slmgr.vbs /rearm
Run that command once every 30 days to keep going until you can afford a license.
