| 摘 要： | 由于安庆地震台数字化测震仪及分析软件所测定的地震震级与中国地震台网中心(CENC)所测定的地震震级偏差较大,选用安庆地震台9个月的观测资料从MB震级与MS震级两个方面进行分析,在相关性较好的基础上,得出单台定位的台基校正值,并分析了偏差产生的原因,为安庆地震台单台地震分析工作提高准确度提供了一定的理论基础.

| Abstract: | Compared to the China Earthquake Networks Center（CENC） ,there are larger earthquake magnitude deviations measured with the digital seismograph and analysis software at Anqing Seismic Station. In this paper, the Ms and MB magnitude are analyzed using the observational seismic data recorded at Anqing Seismic Station for 9 months. As a good correlation, we got the magnitude calibration values for Anqing Seismic Station. The causes of deviations also analyzed. This work paid a theoretical foundation for improving the observational accuracy of Anqing Seismic Station. |
