红山地震台面波震级Ms的研究
|
摘要
本文选用了红山地震台ＤＫ－１测震记录仪记录到的１９８７年—１９９０年Ｍ＿ｓ≥４．８地震共１１６４次，这些地震分布在全球各个区域。我们参照国家地震局地球物理研究所编篡的《中国地震台临时报告》￣［３］中的震级以及有关资料，对红山地震台所测定的面波震级Ｍ＿ｓ进行了对比、讨论。结果认为红山地震台以往测定的面波震级基本合理，对于６级以上地震震级相对偏差较大；通过震中距△分区间深入研究，我们给出了每个区间的面波震级台基校正值，供实际工作中参考使用。
The article has selected and used 1164 earthquakes with M_s≥4.8 distributed all over the world during 1987 1990,which were recorded by the DK-1 sersmography in Seismic Station Hongshan. With reference to the magnitudes of“preliminary Seismologi-cal Report of Ghina Seismic Station”compiled by Institute of Geophysics of State Seis-mological Bureau and other relative data, the article has compared and analysed the sur-face wave magnitudes Ms determined by Seismic Station Hongshan. The results show that the surface wave magnitude is generally reasonable,but for the magnitudes greater than 6.0 there is a bigger deviation.To further research various regions by epicenter dis-tance △, We have provided a correct value of surface wave magnitude for each region as a reference of the practical use.
