广东省台网震级M_L的台站校正值

ON THE CORRECTION COEFFICIENT TO DETERMINE THE MAGNITUDE M_L FOR THE SEISMIC NETWORKS IN GUANGDONG PROVINCE

利用广东省地震台网多年的观测资料,选取了481个地震的数据计算了19个台站的M_L震级校正值。初步的结果表明,震级校正值受震中距、震级等因素影响较小,可以满足实际工作要求。

The correction coefficient of magnitude ML at 19 seismic stations is gained by selecting 481 seismic data and by using the observational data of seismic networks in Guangdong Province. The primary result shows that although some factors, such as epicentral distance, magnitude, have small influence on the values, they are suitable for our practical work.
