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.


I did manage to get the earthquake trace data from the remote station that handles it.
