| 摘 要： | 针对2013年9月20日甘肃肃南、青海门源交界5.1级地震,研究了其地震矩加速释放现象。采用不同的空间半径进行了"时-空"扫描计算,结果显示该地震前具有明显的地震矩加速释放现象,随着扫描半径的不同,异常表现为"异常出现—减弱—增强—发震"的特点,因此该方法在实际地震预测中具有一定的实用意义。但由于地震矩加速释放模型的研究较为复杂,影响因素较多,本文也只是针对一个震例进行了研究计算,因此更深入的研究工作需要在后续工作中展开。

STUDY ON ACCELERATING MOMENT RELEASE(AMR) BEFORE MS 5.1 EARTHQUAKE AT THE JUNCTION OF GANSU SUNAN AND QINGHAI MENYUAN ON SEPTEMBER 20, 2013 |

| Abstract: | Focusing at earthquake happening at junction of Guansu Sunan and Qinghai Menyuan on Spetember 20, 2013, we have carried out some researches on Accelerating Moment Releasse(AMR). Different spatial scale is used to carry out "time-spatial" scan calculation. The results show that there is obvious AMR phenomenon before main shock happens and It seems that AMR phenomenon appears at first, then it becomes weak later and strongest finally when main shock happens. So the AMR method has some kind of useful value for daily practical works. One point must be given that because AMR method is extremely complex and lots of factor effecting results have not mentioned on this paper, and it only one earthquake example, so some further works needs to be done in the future. |
