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.[著者文摘]
