摘要
龙陵地震是由８个６级以上地震组成的强震震群序列。采用地震活动图象和震源机制资料的构造分析方法，得到带有运动学和动力学特征的震源破裂组合在地面的投影图象。配合其它资料，提出龙陵地震序列强震的破裂特征是：由３条北东东向左旋走滑断层和２条北北西向右旋走滑断层组成的共轭破裂组合。进一步讨论了某些有关的地震地质问题。
The Longling earthquake sequence is an earthquake swarm including strong events of M≥8. The project of the pattern of the source rupture combination with kinetic and dynamic features on the ground was obtained by tectonically analyzing the seismicity pattern and source mechanisms. Combined with other data , the rupture characteristics of strong events in the Longling earthquake sequence .was found. It is a conjugate rupture combination of 3 NEE faults with left-lateral strike-slip and 2 NNW faults with right-lateral strike-slip. Some related seismogeological problems were further discussed.
