| 摘 要： | 用“双差法”对2002年12月14日甘肃玉门5．9级地震的主震和余震序列进行了重新精确定位，在此基础上讨论了本次地震的发震断层和发震机制。结果表明，在汇合处玉门断裂向深部延伸和旱峡一大黄沟断裂汇合在汇合处的断层面上发生逆推错动，造成这次主震和余震的能量释放。

| Abstract: | The sequence of the Yumen M5.9 earthquake on December 14, 2002 was relocated using the double-difference earthquake location algorithm. Based on this the seismic fault and mechanism were discussed. The result shows that the inverse-push dislocation occurred on the fault plane at the convergence of the Yumen fault and the Hanxia-Dahuanggou fault in the depth, and both faults contributed to the energy release of the mainshock and aftershocks. |
