| 摘 要： | 采用地形变前兆特征研究中的多种方法,利用常熟台定点形变观测资料,对自1985 年以来发生在江苏省及南黄海海域的中强地震进行了研究及观测手段的映震能力检验,得出:(1) 常熟地倾斜对其周围200 km 范围内MS≥4-5 地震有较好的中、短期前兆异常显示;(2) 归纳总结各分析方法判别获得的异常表明,常熟地倾斜单台信度较高,具有较强的映震能力。

| Abstract: | The responses of Changshu fixed point deformation observation to the Jiangsu and south Yellow Sea earthquakes occurred since 1985 are tested. It is concluded that (1) the tilt observations of Changshu seismological station can show better short medium term precursory anomalies of the earthquakes of M S≥4.5 around 200 km; (2) its observation credit is higher, better ability responded to earthquake. |
