| 摘 要： | 震级是大震速报中最基本的参数之一,震级偏差的大小直接影响资料的使用及台站的速报质量。本文根据兰州地震台测震数字化记录3年的资料,对此期间所发生的158例中强地震的震级进行统计,与《中国地震台网观测报告》提供的标准震级进行对比,对其偏差形成的几种因素进行分析,初步得出校正值,有利于提高兰州台速报地震震级的准确性。

| Abstract: | The magnitude of earthquake is one of the most primary parameters in earthquake prediction. The usage of data and quality of timely prediction are directly affected by its deviation. Based on digital data of 158 middle-strong earthquakes recorded in Lanzhou Seismic Station in 3 years, the factors causing magnitude deviation is analyzed by compare with standard in the Report of China Seismic Net and adjusting value is obtained for improving the prediction precision of earthquake magnitude in Lanzhou Seismic Station. |
