【摘要】 基于前兆数据跟踪及分析应用,对海拉尔台重力潮汐滤波观测值在远震前后有向下扰动的现象进行分析,对海拉尔地震台和乌加河地震台的重力潮汐滤波观测值在全球Ms7.0以上地震、中国大陆Ms6.0以上地震的震后效应及同震响应进行统计。得出,海拉尔台重力潮汐滤波值中叠加向下扰动属非地球物理事件。更多还原

【Abstract】 The downward disturbance appeared in filtered data of tidal gravity at Hailaer Station before and after distant earthquake is analyzed based on tracking and analysis of precursor data.Post seismic effect and coseismic response of filtered data of tidal gravity at Hailaer Station and Wujiahe Station to earthquakes of Ms≥7.0in globe and earthquakes of Ms≥6.0in Mainland of China are conducted statistics.It is concluded that the downward disturbance of filtered data in tidal gravity at Hailaer Station is not related to geophysical event.更多还原
