| Abstract: | This article selected the S-wave records of 17 digital seismic stations at the junction of Hebei Shandong and Henan provinces to screen the earthquake in the junction area. The seismic waveforms recorded by the stations were strictly measured and extracted, and the S-wave splitting during seismic wave propagation was analyzed and the geophysical anomalies was characterized by S-wave splitting before moderate earthquakes. |
