Selection of coherent waveforms. a Raw seismograms of event 3 recorded by Hi-net stations whose names start with letter “I.” Horizontal axis is the lapse time from the theoretical arrival times of PKiKP. b Seismograms from a are band-pass filtered with cutoff frequencies of 2 and 5 Hz. c The selected set of coherent waveforms after employing the cross-correlation matrix method (Tkalčić et al., 2011) is shown by cyan lines
