| 摘 要： | 通过对河南荥阳地震台水管观测记录中的60例“高频抖动信号”,与周围250 km范围内地震事件在时间域的前兆响应的统计分析,结果表明,这种信号与地震事件之间具有一定程度的前兆响应关系.认为该高频抖动信号与周围地震具有内在的关联性,是地壳形变过程的一种前兆反应,具有一定的前兆意义.

| Abstract: | The analysis on the relationship between 60 high-frequency tremble signals in water tube observation curves recorded in Xingyang Seismic Station and earthquake activities indicates that these signals have some relevance with the earthquake activities. The correlations are of great importance for prediction as a precursor of crustal deformation. |
