山西省数字台网与模拟台网震级的对比研究

统计分析了山西省数字地震台网考核运行 3个月以来的记录地震的震级情况 ,将两套人机交互处理系统 (泰德和港震系统 )测定的速度震级及港震系统仿真后 (DD— 1)测得的位移震级 ,与山西省模拟台网 (即大同、太原、临汾、长治 9个模拟人工值守台 )所测定的位移震级进行了对比 ,研究了它们之间的相关程度、一致性、差异性 ,得出港震系统与泰德系统测定的速度震级与模拟震级、数字系统仿真 (DD— 1)后测定的位移震级与模拟震级相关系数均在 0 .940以上 ,相关性较好的结论

Comparison of Magnitude from Simulated Seismic Network and Digital Seismic Network in Shanxi Province

The situation of the magnitude recorded the earthquakes from the digital seismic network of Shanxi province since the 3 months of the test operation had been analyzed,the velocity magnitude determinated by the 2 men-machine interactive processing systems (Taide system and Gangzhen system) and the post emulated displacement magnitude from Gangzhen system were compared with the displacement magnitude determinated by the simulated seismic network in Shanxi (i.e. 9 artificial watch stations of Datong,Taiyuan,Linfen,Changzhi),the correlation,consistency and difference between these magnitudes were analyzed.A conclusion was obtained that the correlation coefficient of the above-mentioned magnitudes is above 0.940 and their correlation is quite good.
