【摘要】 结合朝阳及周边地区地震,分析地震前朝阳地倾斜观测数据异常变化,结果表明朝阳地倾斜观测在周边Ms≥3.0级地震发生前存在较明显的震前倾向异常变化,并具有以下特征:(1)同一方位的地震,震前出现地倾斜倾向异常的分量具有统一性,且加速方向具有一致性;(2)朝阳地倾斜观测倾向异常有较强的方向性,但幅度特征不明显,与震中距关系不大。更多还原

【Abstract】 Combined with the earthquakes in Chaoyang and surrounding area, the abnormal changes of observation data of ground tilt are analyzed. The results showed that there were obvious changes before Ms≥3.0 earthquakes occured And it has two characteristics as the following showed:(1) Earthquakes of the same range, has the unified components of the ground tilt abnormality before the earthquake occured;( 2) Chaoyang ground tilt observation tendency anomaly has a strong direction, but the amplitude characteristic is not obvious, which has has little relationship.with the epicentral distance.更多还原
