Cross-correlation of the waveforms of each pair in the cluster confirmed the similarities. Re-sample technology is used to improve the sampling rate, which is helpful to distinguish the small variation of shear wave splitting. The variation of shear wave splitting could be found directly from seismograms of each pair in a cluster.展开更多
