| Abstract: | This paper concluded the basic characteristics of the dynamic anomaly of the water level in Wan no. 1 well before occurrence of Dedu moderate earthquake and pointed out the four-step anomaly reflecting earthquakes of water level in Wan no. 1 well: steeply sudden drop-slow elevation-jumping at high level-stable earthquake occurrence at high level. Author also conducted the comparative analysis on the short-term and impending anomalies and discussed the important significance of the four-step anomaly reflecting earthquakes of the short-term and impending earthquake prediction. The problems concerned with the anomaly field of the regional stress and sensitivity were also discussed. |

| Keywords: | Dedu earthquake dynamic level of deep ground water anomaly reflecting earthquakes congnate relation of earthquake and ground water implication for earthquake prediction |
