摘要
处理了聊古一井 1 981年至 1 998年氦的观测资料 ,发现在较近的 3次 5级以上地震发生前 ,氦的年动态有明显的异常变化 ,作者分析后认为 ,可以把该井氦的年动态异常作为附近 5级以上地震预报的参考指标。
In this paper,the data of observed Helium content in Liaogu 1 well from 1981 to 1998 has been processed,and it has been found that the Helium's yearly dynamic variations have clear abnormal changes before three earthquakes occured nearby with magnitudes greater that five.After analysis,the authors think that Helium's yearly dynamic anomaly in this well could be used as the prediction index for nearby earthquakes with magnitudes over five.
