| 摘 要： | 结合新疆构造活动的特点及地震活动的分区,探讨了境内强震活动的迁移特征,结果表明新疆强震活动始于乌恰地区,分别沿南天山西段由南向北迁移和沿西昆仑带由西向东迁移。其迁移方式主要表现为天山带强震活动由低纬向高纬地区成组迁移,各带内次级活动区的往返迁移。研究结果将为判断新疆各区(带)地震活动的趋势及强震危险地区提供依据。

| Abstract: | Combining tectonic characteristics with regional dividing of seismic activity of Xinjiang, the migration characteristics of strong earthquakes in Xinjiang are discussed. The result shows that the strong earthquake activity which starts in Wuqia area migrates from south to north along the west part of South Tianshan, and from west to east along the West Kunlun. The manner of migration shows the phenomenon that the strong earthquake activity in Tianshan Zone migrates from low latitudes to high latitudes and migrates repeatedly in active subareas of each zone. The research result would provide evidence for identifing the trend of earthquake activity and the strong earthquake risk area of each seismic belt and region in Xinjiang. |
