| 摘 要： | 通过分析,研究了青海及邻区Ms 6．8强震在不同地震带之间的迁移规律;6级地震在各个地震带内部不同地段的迁移特征及不同时段。强震集聚区在各个地震带的相互迁移规律和循环特征。研究结果表明,强震存在北东方向的迁移规律。同一个地震带内存在沿规模宏大的主活动断裂自西向东或者由东向西的迁移规律。利用马尔科夫过程讨论了其迁移概率。

| Abstract: | The migration pattern of strong earthquakes among different seismic-regions in Qinghai province and adjacent area, migration characteristics of MS 6.0 earthquakes among different areas in a seismic-region, migration and recurrence characteristics of strong earthquake assemble areas among each seismic-regions and different periods are analyzed and studied. The results suggest a northeast direction migration pattern of strong seismic action, and a pattern of strong seismic action migrating from west to east or from east to west along the great main active fault within a seismic-region. Migration probability is discussed using Markov method. |
