| Abstract: | Taking five underground water level observation wells with high earthquake response capability and located in Shanxi, Hebei and Inner Mongolia as study objects, this paper studies and discusses the generality of precursor waves in well water levels before strong earthquakes. It is indicated that the precursor waves often happen before strong earthquakes, with the ratio of occurrence up to 65% (41/63); the precursor waves have poor generality in different observation wells, which may be related to the different well-aquifer system of different observation wells and the different source parameters of earthquakes. Compared to the seismic water level fluctuations in a single well, the number of precursor wave times recorded in well water levels before strong earthquakes is slightly less than that of seismic water level fluctuations, with a ratio between 39.7% and 50.7%, respectively. The number of observation wells with precursor wave recordings before earthquakes accounts for up to 66.7% of the total number of observation wells. The precursor wave in well water level records has a certain generality in terms of the number of times recorded and the spatial distribution, except for its manifestation characteristics. |
