A screenshot of the SEISAN software60 with an example of picking an event with the magnitude of 5.5 located at a distance of ~ 70°. The left panel shows the initial seismogram without filtering, in which the arrival wave is almost not visible. The right panel shows the result of the bandpass filtering in the frequency range of 1–5 Hz, which was found most appropriate in this case. The blue indications highlight theoretical phases, and the red ones indicate the manual picking results.
