| Abstract: | The precursory anomaly of the south Yellow Sea of M S 6.1 on Nov.9, 1996 has been obtained using three well table record of groundwater dynamic observation network in Chao Lake through statistic processing. Their anomalies are mainly short medium term, and not synchronism. Finally, some problems of how to enhance the accuracy of earthquake prediction and the effect of rain to well table are discussed. |
