| 摘 要： | 以永胜、金官盆地和巍山、弥渡、祥云、云南驿等盆地分别作为程海断裂北端和南端结构,不难发现,随着时间的推移,断裂的活动部位不是固定不变的。侧向迁移是端部断裂活动转化的一种形式,断裂的不断更新使程海断裂端部地震活动增强。侧向迁移总是向着区域某一条地震带方向发展。

| Abstract: | Taking Yongsheng and Jinguan basins and Weishan, Xiangyun, Midu, Yunnanyi basins as the structures respectively of the northern and southern ends of Changhai fault zone, it seems to show that the active segments of faults tend to show time-dependent migrations. Lateral migration is a pattern of seismicity transformation at the fault's ends. The renewed activities of the fault strengthened the seismicity. As a whole, lateral migration tends to propagate toward the earthquake belt in an adjacent area. |
