摘要
利用常用的形态分析法,对阿合奇地震台地倾斜仪数字化观测数据进行分析,发现在距离台站300 km以内的MS5.0以上地震发生前,地倾斜仪通常会出现不同程度的短临前兆异常。研究结果表明:阿合奇地震台数字化地倾斜仪观测数据映震效果明显,异常特征主要表现为倾斜的反向变化、速率变化、固体潮形态畸变等。
Using morphological analysis method, this paper analyzed short term anomalies of ground tilt in Aheqi station before earthquakes with Ms5.0 for epicenter about 300 km. The results showed : the earthquake reflecting ability of ground tilt in Aheqi was significant and anomalies appeared with reverse change, velocity change and solid tide distortion.
