- Abstract:
- In this study,a correlation analysis method was used to determine the azimuths obtained from several seismometers deployed at the surface from the same station,and the method was carried out at 5 borehole seismometers deployed in Yancheng,Jiangsu Province,Jieshou,Hefei,Fuyang,Anhui Province,and Hanghai,Henan Province. Meanwhile,we used the teleseism P-wave polarity method to verify the azimuth of the surface and borehole seismometer. The results show that the deviations of the waveform correlation analysis method and teleseism P-wave polarity method from the gyro north seeker detection results in the seismometer azimuth detection of surface seismic stations are within 0.4° and 2.9°, respectively. The deviation between the waveform correlation analysis method and the teleseism P-wave polarity method is within 5.5° in the seismometer azimuth detection of borehole seismic stations. Therefore, both the teleseism P-wave polarity method and the waveform correlation analysis method can obtain satisfactory results.
