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.
