摘要
通过对云南省及邻近地区7级大震,震前群井水位记震能力变化的研究及异常、预报指标检验,表明震前记震能力减弱或消失与近大地震有关。其异常特征表现为形态相似、时间同步、幅度明显等特点。井孔水位记震能力变化可能是地下水中期预报地震的一种新方法。
Through a study of the recording capacity variation of water level in wells and a review of anomalies and predictive indicators before large earthquakes (M = 7.0) in Yunnan and its vicinities, it is suggested that the recording capacity decrement or dying out before those events has something to do with the impending large events. The anomalous characteristics show the similar shape, synchronous time, and obvious amplitude. The recording capacity variation of water level in wells might be a new method for the intermediate-term prediction in groundwater research domain.
