摘要
采用气象学上的累年均值法 ,求取了门源地倾斜的正常年变形态 ,然后利用形态法 ,对震前异常形态与正常年变形态相比较 ,通过震例分析 。
The authors have got the normal annual variation of ground tilt in Menyuan area by using the method of meteorological cumulative annual mean value, compared the abnormal and normal annual variations before Menyuan earthquake by using the morphologic method,and summarized the precursory anomalous characteristics and impending earthquake index of ground tilt in Menyuan area.
