摘    要:
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)等中强以上过程中的区域垂直应变率动态演化特征;在此基础上,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。

关 键 词:垂直应变率 动态图像 演化特征 强震预测 地震

Abstract:
Making use of the method of obtaining areal vertical strain rate from areal precision levelling data and gaining dynamic pictures combining with deformation data on spanning fault,the areal vertical strain dynamic evolution characteristics of several modenately strong earthquakes such as Lijiang ( M s 7 0) and Menyuan ( M s 6 4) earthquakes occurred in crustal deformation monitoring areas which are located at the West Yunnan and Qilianshan|Hexi;On the basis of above|mentioned,by studying the time|space nonhomogeneity and strain energy accumulation status,some medium|and short|term strong seismic risk,area criterion according to the areal vertical strain rate dynamic information are proposed.
Keywords:Area vertical strain rate Dynamic pictures evolution characteristics Medium|and short|term prediction criterion of strong earthquakes
