| Abstract: | In this paper, the polarization analysis technique, proposed by prof. Stuart Cram-pin, is applied and digital seismic data is processed by filtering and transfering. The authors discuss S-wave splitting of local earthquakes occurred in Tangshan region, and give that the azimuth of main compressional stress field is north-east diretion. |
