IASPEI宽频带面波震级与传统面波震级的对比
|
摘要
应用IASPEI新推荐的宽频带面波震级M_S(BB)标准,选取云南数字地震台网记录到的2000~2011年云南及周边地区4.0级以上的433个地震事件为研究对象,测定其宽频带面波震级M_S(BB),同时也重新测定面波震级M_S,并采用线性回归和正交回归方法,对M_S(BB)与M_S进行对比分析研究,得到了它们之间的回归关系式。结果表明:M_S比M_S(BB)系统偏高,当震级较大时,二者之间差别也偏大。
We applied the newbroadband surface wave magnitude MS( BB)standard recommended by IASPEI to determine the broadband surface wave magnitude M_S( BB),and re-determine the surface wave magnitude MSof the selected 433 M≥4. 0 seismic events in Yunnan and its adjacent area recorded by Yunnan Digital Seismic Network from 2000 to 2011. Then we compared and analyzed M_S( BB)and MSby using linear regression and orthogonal regression method,and obtained the relationship between them. The results showthat MSis higher than the M_S( BB)for the same earthquake,and the difference between them is large when the magnitude is lager.
