利用从区域精密水准重复测量资料中分离提取区域性垂直应变率与跨断层形变观测相配合生成的动态图像方法 ,分析了发生于滇西和祁连山 -河西地形变监测区及附近的丽江(MS7 0 )、门源 (MS6 4 )等中强以上地震过程中的区域垂直应变率动态演化特征 ;在此基础上 ,通过对孕震过程区域垂直应变率动态信息的时空非均匀性与应变能积累状况的研究探讨 ,提出了一些根据区域垂直应变率动态信息判定中短期强震危险区的判据。
Based on the dynamic image generated by separating and extracting the regional vertical strain rate and the cross-fault deformation observation from the regional precision leveling repeated data, the effects of the dynamic images generated in the west of Yunnan and Qilian Mountains and the Hexi Terrain Monitoring Area (MS7 0 ), And the source of MS6 4, and so on. On the basis of this, the dynamic characteristics of the vertical strain rate in the process of seismogenic process are analyzed, including the spatial-temporal heterogeneity and the accumulation of strain energy , Some criteria for judging the danger zone of medium and short term strong earthquake based on the dynamic information of regional vertical strain rate are put forward.
