摘要： 分析研究川滇及邻区地下水异常在中期— 短期— 临震孕震阶段认为, 异常时空转移是地震短临跟踪的一种有效方法。根据中期— 短期— 临震异常井孔数量少— 增多— 减少( 密集) 等变化, 判定地震孕育所处阶段。并用有无区域性异常时空转移等特征预测强震和非强震;用异常时空转移的方向大致估计可能的发震地区;用短临孕震阶段时空转移的明显程度预测发震时间。

Abstract: Research on the medium-term sho rt term and imminent underground water anomalies in Sichuan-Yunnan and neighboring areas show s that the time-spatial diversio n is an effective method for sho rt-term and imminent tracing of seismicity.We may judge the stage of seismogenic process acco rding to the medium-term, short term and imminent variation of the number of anomalous wells, i.e.the number of anomalous wells decreases, increases, then decreases, and may use the phenomenon, i.e.whether there are time-space diversion of regional anomalies, to predict the strong earthquakes, and also may use the direction of time-space diversion to est imate the seismogenic region, use the ex tent of sho rt term and imminent timespace diversion to predict the occurrence time.

Key words: Anomaly of underg round water, Time-spatial diversion, Strong earthquake prediction
