Figure S3. Regional scale network dectection results using repeating earthquakes near Taiwan island. (a) Calculation results of three channels CC and σSF for repeating earthquakes near Taiwan island with a bandpass filter of 0.05-0.1 Hz. The value of CC and σSF of the repeating earthquake events recorded by 173 permanent stations of the GD, FJ, HI, GX, GZ, SC network stations in Mainland China are listed. (b)-(d) The CC and σSFdistributions of the detection results of repeating earthquakes recorded by regeonal-scale permanent seismic stations in mainland China. The red outliers represent the 3, 4, and 3 anomalous stations in BHN, BHE, and BHZ, respectively.
