| 摘 要： | 运用直接调和分析和速率合成方法对岫岩地震前后烟台形变观测资料进行了处理分析。结果表明,岫岩5.4级地震前,烟台地区形变观测资料出现了短临前兆异常,此次异常很可能是岫岩发震断层活动引起了相关的蓬莱-威海断裂活动,最终导致区域应力场增强的结果。 |
| 关 键 词： | 岫岩地震 形变异常 发震断层 烟台地区 |

| Abstract: | By using the methods of direct harmonic analysis and velocity synthesis,the deformation data observed at Yantai monitoring station before and after the M_S5.4 Xiuyan earthquake were analyzed.The results show that short-term deformation anomaly emerged before the event.The anomaly probably is the result of regional stress field enhancement caused by the motion of Weihai-penglai fault triggered by Xiuyan seismogenic fault. |
| Keywords: | Xiuyan earthquake Deformation anomaly Seismogenic fault Yantai area |
