| 摘 要： | 通过对通河地震台、延寿地震台多年水位数据的分析,发现通河地震台与延寿地震台水位对周边中强地震有一定的响应。统计了扰动异常与地震的对应关系,总结了通河、延寿水位几次扰动异常形态、特征、指标。通河地震台和延寿地震台水位出现扰动异常,且扰动成组出现,持续几个小时以上,最大振幅超过7mm,最大周期超过6min,异常结束后一个月之内在测井周边550公里范围内,有发生3.0级以上地震的可能,其扰动持续时间越长,震级越大。

THE WATER STAGE OF THE TONGHE SEISMIC STATION AND YANSHOU SEISMIC STATION REFLECTING SHORT-TERM ANOMALIES OF THE EARTHQUAKE CHARACTERISTICS |

| Abstract: | Through years’ data analysis of the water stage of TongHe ,YanShou Seismic Station,the author finds that the water stage of TongHe,YanShou Seismic Station has a certain response on surrounding moderately strong earthquakes .At the same time, it counts the correspondence between abnormal disturbance and earthquake,and summarizes morphology,charateristics,indicaters when abnormal disturbance of the water stage of TongHe,YanShou occurred several times before. The disturbance occurs in groups ,continues for several hours and its maximum amplitude is more than 7mm and the maximum amplitude is more than 6min. 3.0 earthhquake may occur within one month and 550Kmarround longing after disturbance ends. Meanwhile, the longer the disturbance continues, the greater the magnitude becomes. |
