I did clean the file of any frequnacy above 1Hz, becose of local noise
that was in the recording on higer frequancyes.
I was not expecting that to be able to detect earthquake at this
distance. Since my geophone is short period and not ment for this type
of event at this distnace. I know that I can detect earthquakes that are
at the distance of ~860km and around size mag 4.6 - 5.0 at that range.
So far, emsc-csem says the earthquake is 7.7Mw.
