| 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. |
