| 摘 要： | 通过分析通海地震台垂直摆倾斜观测数据的长期、中期、短临、临震异常，发现2014年10月7日景谷6.6级地震发生前，观测数据曲线年变幅度变小，出现跳跃式变化，在地震发生前4天，NS向逐渐升高、突然降低，变化幅度达179×10-3"，具有长期、短临及临震异常特征。分析认为，通海地震台垂直摆倾斜形变响应数据，较好预示了此次景谷6.6级地震的发生。

| Abstract: | Based on analyses of the long-term, medium-term, short-impending and impending anomalies for the deformation data of vertical pendulum tilt observed at Tonghai Seismic Station before Jinggu M 6.6 earthquake on Oct. 7, 2014, we found that there were an annual variation amplitude decrease and jumping variations in the observed data, and the tilt deformation in north-south direction increased gradually and then suddenly decreased before 4 days of the occurrence of Jinggu M 6.6 earthquake, the variation amplitude reached 179×10-3". It is concluded through analyses that the vertical pendulum tilt data observed at Tonghai Seismic Station provided a fairly good indication for Jinggu M 6.6 earthquake on Oct. 7, 2014. |
