| Abstract: | Taking the earthquake of ML5.5 of Wenan,Tianjin,as an example,abnormal variation appeared in fluid observation in Tianjin region before the shock is analyzed.The result shows that obvious short-term precursor anomalies occurred in wells of Wang No.3,mercuric gas in water and water levels in Pangzhuang and Hangushuangqiao wells in Tianjin before the earthquake. |
