静乐井水位前驱波重现性问题探讨

Discussion about the reproducibility problem of Jingle well water level precursors

以山西静乐井为研究对象,对井水位前驱波重现性问题进行了探讨。结果表明,相似地震前前驱波起始时间和波动周期在一定范围内具有较强的重现性,其比例可达63.1%;部分相似地震前前驱波的波动形态和幅度也存在一定的相似性,但在研究范围内前驱波各项特征均相似的地震尚未发现,其原因可能与前驱波的成因、传播途径、相似地震的震源区特征等因素有关。

Choosing the Jingle well in Shanxi as the research object, the paper discusses the reproducibility problem of well water level precursor waves. The results show that the start time and fluctuation cycle before similar earthquakes are highly reproducible, the ratio of which is up to 63.1%. The fluctuation form and amplitude before some similar earthquakes are of certain similarity, but the earthquakes with all similar precursor features were not found in the research scope. The reason may be related to origin and transmission route of the precursor wave as well as seismic zone characteristics of the similar earthquakes.
