| 摘 要： | 丽江７．０级地震序列发生在该地区属次级构造的断裂上，而且这次地震的烈度分布，地表破坏分布和强余震分布都表现了异常不均匀性。根据大震震害损失评估调查和大震现场地面破坏调查取得的资料，对上述异常现象的原因进行了初步分析，认为主震发震构造为玉龙山山前近南北向断裂，但其破裂过程可能存在“跳跃”和偏转。

| Abstract: | The seismic sequence of the M 7 0 Lijiang earthquake occurred in the second-order fault in this area, and all the distributions of the intensity, surface damage and strong aftershocks display abormal inhomogeneity.The preliminary analysis of these abnormal phenomena has been made on the basis of the data from the evaluation and survey of the earthquake damage and the survey of the surface damage for the earthquake on the spot.The authous think that the seismogenic structure of the mainshock is the piedmont fault in near NS in Yulong mountin, but skipping and deflection may have occurred in the rupture process. |
