| Abstract: | After analyzing the practical needs of azimuth correction and technical requirements of azi-muth survey for seismic stations,the method for the installment of orientation signs in seis-mic stations is proposed in this paper.Then,the method for orientation determination with newly installed seismograph and the operation approach to make correction in azimuth survey with long-term running seismograph is illustrated.Besides,the detection method to deter-mine polarity of the seismograph in a vault or on a pier is also discussed. |
