STUDY OF RELATIONSHIP BETWEEN PULSE TYPE CHANGE OF WATER LEVEL AT XINGJI-1 WELL AND SEISMICITY

Based on collecting and sorting of Xingji-1well water level data since 1998 and M_L≥4.0 earthquakes within the range of 260 km from the well,the pulse type changes of the water level are studied to explore the cause condition of the water level anomaly and the mechanism of the pulse type changes.In the end,the earthquake reflecting ability of the water level data of Xingji-1 well is evaluated.
