【摘要】 对比安西地震台数字记录所测定远震面波的震级与中国地震局给出的平均面波震级(Ms)的偏差,分析它们之间的相关程度、一致性、差异性,初步结果表明安西地震台测定的震级比中国地震局的平均震级略高0.04。这种偏差是在测量误差允许范围之内,最后给出了安西地震台不同方位、不同震中距的参考校正值,并得到较好的校正结果。更多还原

【Abstract】 The differences among the surface wave magnitude by Anxi digital seismic station and the average magnitude determined by China Earthquake Administration( CEA) are compared in the paper. The correlation,consistency and differences are analyzed,the preliminary results show that the magnitudes recorded by Anxi digital seismic station are 0.04 greater than average magmintudes of CEA,which is in the range of allowable error. Finally,the corrected value is obtained by different azimuthal angle and epicentral distance in the paper.更多还原
