| 摘 要： | 1978年7月13日四川省黑水5.4级地震前,附近温江地区五个台的地倾斜显示出了几种短临异常特征,即震前10余天倾斜单分量日均值曲线出现了大幅度的变化;倾斜的速度变快;震前倾斜矢量打结,结的长轴方向基本指向震中,出结方向背向或指向地震方向;震前几天倾斜方向发生偏差等。这些异常是预报地震的依据之一。

| Abstract: | Before the Heishui earthquake (Ms=5.4) of July 13,1978,in Sichuan province, some short term and imminent anomaly characteristics of the ground tilt were recorded by five tiltmeters in Wenjiang area. About ten days before the earthquake the tilt monodirectional components daily daerage values curve showed a big change and a acceleration of tilt. Before the earthquake the tilt vectors tied. The long axes of the ties almost pointed to the epicentre. The directions coming out of ties pointed to the place where the earthquake took place or back from the future earthquake. For some days before the earthquake the deviations of tilt directions appeared. These anomalies can be regarded as one of the bases of predicting earthquake. |
