| 摘 要： | 在对构造运动差异较大的柯坪块体和天山中部地区地震活动研究基础上,深入分析了这两个不同构造单元的中强地震活动对整体新疆地震形势的影响。不同构造环境下不同构造单元地震活动差异性很大。柯坪块体内构造运动强烈,它是新疆6级地震主要活动区之一。6级地震发生后的1年内,天山地震带是中强地震的主要响应区,在时间上具有短期预测意义。位于特殊构造环境的中天山地区地震少,地震强度低。4次5级地震后的1~3年,新疆地震活动呈明显增强趋势,中天山地区中强地震活动对周边地区中强地震活动会产生触发作用。

| Abstract: | Based on seismicity study of Keping block and middle Tienshan region with great difference of tectonic motion,we analyze thoroughly the influence that the mid-strong earthquake activity in two tectonic blocks acts on the whole Xinjiang seismic situation.The seismicity in different blocks under different tectonic conditions is diverse.Tectonic movement of Keping block is strong and concentrative active region of Xinjiang M_S6 earthquake.Within one year after M_S6 earthquake occurring,Tienshan seismic belt is main response region of mid-strong earthquakes,which is significant for short-term prediction.There occurs few earthquakes with weak intensity in middle Tienshan region locating in special tectonic conditions.Within 1 to 3 years after four M_S5 earthquakes,Xinjiang seismicity trends to increase remarkable,and mid-strong earthquake activity in middle Tienshan region could trigger seismicity surrounding Xinjiang. |
