Calculation results of correlation coefficient of abnormal
recording
stations
Figure S2 represents calculation results of three channels’ CC and
σSF for mainland China permanent stations with the
repeating earthquakes near Japan island. The values of CC and
σSF of the repeating earthquake waveforms recorded by
842 stations in mainland China are listed, of which 18 stations exceed
the thresholds.
Figure S3 demonstrates calculation results of three channels CC and
σSF for seismic networks in the southeast of China with
repeating earthquakes near Taiwan island. The calculation results of
three channels CC and σSF for repeating earthquakes near
Taiwan island are listed; and stations with abnormal records were
detected, of which one station had three channels outside of the
confidence interval (HI.LSH) and five had one or two channels outside of
the confidence area (HI.SLL, SC.TQ, FJ.PTLC, SC.BZH, SC.DFU).
