- Abstract:
- A earthquake of MS6.4 occurred at Ning'er county of Yunnan Province on June 3,2007.For a study of seismometric precursor of the earthquake,the method of spatial scan is used,and spatial evolution of earthquake frequency in Chuandian region before the earthquake is studied.Earthquake activity in Chuandian region continued enhancing before the earthquake since Feb.2007.Earthquake activity of Simao area had enhanced from Feb.to Apr.2007,then weakened in May.2007.Enhancing earthquake activity in Wenshan area occurred in the same period.A primary discussion of seismogenic process of the Ninger earthquake is present from viewpoint of stress field,which shows the occurrence of Ninger earthquake may be related with the difference of earthquake activity evolution between Simao and Wenshan.
