| 摘 要： | 分析库尔勒国家数字地震台2013年1月至2014年12月测定的1 403个近震事件,与新疆地震台网发布的地震目录事件进行对比,计算二者的震级偏差值,并从震级、震中距及方位角等分析二者之间的关系。结果发现,随着地震震级的逐渐增大,震级偏差也随着增大;震级偏差与震中距之间也存在着一些联系。

| Abstract: | The analysis of Korla National Digital Seismic Station from January 2013 to December 2014 was the 1 403 earthquake events, event publishing and earthquake catalogue in Xinjiang Seismic Network are compared, the magnitude deviation calculation of the two values, and the magnitude, epicentral distance and azimuth angle analysis of relationship between the two. It is found that the magnitude deviation increases with the increase of earthquake magnitude, and there is also some relation between magnitude deviation and epicentral distance. |
