| 摘 要： | 根据富蕴地震台地倾斜观测资料,对距该台360 km范围内地震震前异常进行了分析.结果表明:①一般情况下,异常的持续时间越长,资料的异常变化幅度越大,震级越大;②地倾斜观测资料的异常形态与震中位置有关,通常是单分量图和矢量图的拐弯处指向震中位置,震前震源区的应力集中往往造成矢量图畸变,单分量图形出现加速的异常特征;③阶跃...

| Abstract: | According to the ground tilt data in Fuyun station, the earthquake precursory anomaly was analyzed about 360 km around the station. The result showed ① Under normal circumstances the longer the anomaly lasted, the larger the data changed, the greater the target magnitude will be; ② the anomaly shape was related to the epicenter location, usually the turning corner of observation date pointed to the epicenter location and the stress concentration of focal area before the earthquake caused vectogram aberrance and single component accelerating change; ③Step is an important display of earthquake precursory anomaly. |
