| 摘 要： | 2001年6月5日乌拉特前旗发生4．8级地震，震中距乌加河台南东80km，震前乌加河台形变出现短临异常显示，震前1－3日观测值超出正常日变值2倍以上，观测人员及时反馈信息，及时跟踪通报异常信息，应用系统前光计算方法滤波、速率检验，该台资料对此地震映震效果较好。本文着重讨论震前出现的短临异常信息。

| Abstract: | some imminent anomalies appeared at Wujiahe crustal deformation station before the M 4.8 earthquake in Wulateqianqi on June 5,2001. The epicenter is 80 kilometers from the station in southeast.From the first days to the third day before the earthquake the observing value exceed 3 times of the normal value.The anomalies were tracked and reported in time.Processed With filtering and rate checking,the data of the station show a good effect in reflecting earthquake.The imminent anomalies before the earthquake is mainly discussed in this paper. |
