乌鲁木齐遥测地震台网测定的地震震级偏差初步分析
|
摘要
利用乌鲁木齐台网测定的2001—2003年469次新疆境内的地震,分别与新疆地震局编目结果进行对比,发现乌鲁木齐台网测定的平均地震震级与新疆地震目录给出的地震震级偏差较小,而台网内各子台测定的地震震级与新疆地震目录给出的地震震级相比,有些子台的震级偏差范围较大,有些则相对小些。计算得出乌鲁木齐遥测台网测定的平均震级偏差ΔM=0.104±0.268。
Comparison on the 469 earthquakes betwecn determined by Urumqi telemetric seismic station network and the catalog of seismological bureau of xinjiang from 2001 to 2003, the result showed the deviation of mean earthquake magnitude determined by Urumqi telemetric seismic station network is Smaller than the catalog of seismological bureau of xinjiang, but some stations' deviation in the seismic station network are large, some stations' deviation in the seismic station network are small. Author found the deviation formula of mean earthquake magnitude determined by Urumqi telemetric seismic network is ΔM=0.104±0.268.
