| 摘 要： | 分析了琼海加积井在苏门答腊MS8.7和MS8.5地震时水震波特征及震后出现的水位阶变特征,初步探讨了水位阶变现象的机理。同时还分析了三亚南滨井、文昌潭牛井在苏门答腊MS8.7和MS8.5地震时水震波的高采样率数字化观测资料,结果显示:3口井的水震波优势周期比较一致,同一地震在不同井孔的水震波幅度差别较大,同一井孔不同震级地震的水震波振荡持续时间不同

| Abstract: | The characteristics of seismic water-level fluctuations of the two Sumatra-Andeman strong earthquakes with magnitude 8.7 and 8.5 on December 26,2004 and March 29,2005 recorded at Jiaji station,Qionghai,Hainan were analyzed,the features of the infreguent "terrace" changes of the well water-level after the two earthquakes also were analyzed,the mechanism of "terrace" of the well water-level changes has been primarily discussed.Then the digital observation information with high sample ratio of the Sumatra-Ande |
