| 摘 要： | 选取赤峰地震监测中心站与阿古拉地震监测站分别记录的2019年2月1日至2021年2月1日418个地震事件，对2个台站所测定的地震震级分别与中国地震台网中心发布的正式目录震级进行比较。结果表明，赤峰地震监测中心站震级平均偏差为 0.178，标准差为±0.312；阿古拉地震监测站震级平均偏差为0.194，标准差为±0.387。MS(CIF)与MS(AGL)间的线性相关系数为0.938，表明二者震级偏差间有较强的线性相关性。另，统计分析了2个台站震级偏差与震级、震中距、方位之间的关系。

| Abstract: | In this paper, we compared the magnitude of 418 earthquake events measured at Chifeng Earthquake Monitoring Center Station and Agula Earthquake Monitoring Station from February 1, 2019 to February 1, 2021 for analysis and statistic. The earthquake events were compared with the official earthquake catalogue magnitude released by China Earthquake Networks Center. The results show that, the magnitude average deviation of the Chifeng Earthquake Monitoring Center is 0.178, the standard deviation is ±0.312; the magnitude average deviation of the Agula Earthquake Monitoring Station is 0.194, the standard deviation is ±0.387. The linear correlation coefficient of MS(CIF) and MS(AGL) is 0.938, showing that there is a strong linear correlation between Ms(CIF) and Ms(AGL). In addition, the relationship between the magnitude deviation and the magnitude, the epicenter distance and the azimuth angle of these two monitoring stations was statistically analyzed. |
