| 摘 要： | 选取2013-2017年吉林测震台网记录的部分地震，按测震台网运行管理细则对地震编目的要求，需对地震波形进行WA仿真处理后测量震级。对比仿真前后震级，发现仿真后量取的震级普遍较大，偏差在0.3以内。因此，地震编目需严格按照细则执行，地震速报使用仿真震级更加准确，而且掌握震级偏差可为新旧震级资料的连续性提供参考依据。

| Abstract: | Selecting some of the earthquakes recorded by Jilin Digital Seismic Network from 2013 to 2017 and conducting WA simulation according to the cataloging requirements of operational management of the seismograph network and then measuring the magnitude, the magnitude deviation before and after the simulation are calculated and comparative analyzed. We find that the magnitude after the simulation is generally larger and the deviation is within 0.3. Therefore, the earthquake cataloging should be executed in strict accordance with the rules. The quick report using the simulation magnitude is more accurate. And understanding of the magnitude deviation may provide a good reference for the continuity of old and new magnitude data. |
