Figure 7From: Application of cluster analysis based on waveform cross-correlation coefficients to data recorded by ocean-bottom seismometers: results from off the Kii PeninsulaHistograms of CC thresholds for P-wave (left) and S-wave (right). The red lines show the number of thresholds from event pairs with the same observation period. The blue lines show the number from event pairs with different observation periods.Back to article page
