滇川地下水异常时空转移特征研究

Research on time-space diversion characteristics of underground water anomalies in Yunnan-Sichuan region

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。

Research on the medium-term short term and imminent underground water anomalies in Sichuan-Yunnan and neighboring areas shows that the time-spatial diversion is an effective method for short-term and imminent tracing of seismicity. We may judge the stage of seismogenic process according 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 estimate the seismogenic region, use the extent of short term and imminent time-space diversion to predict the occurrence time.
