摘要
在研究常熟台水管仪与垂直摆多年倾斜观测资料的基础上,利用潮汐因子调和分析、Nakai拟合检验、小波分析等方法对台站周边约250km范围内发生的高邮-宝应MS 4.9及如东近海MS 3.8等地震前的异常信息进行了提取,对数据异常分析方法进行评判,旨在为以后地震前及时发现地震提供参考。
Based on the year-observation data of vertical pendulum tilt and research of water pipe instrument in Changshu seismic station, we conducted the tide factor of harmonic analysis, Nakai test and wavelet analysis to extract the abnormal information of the range of 250km occurred near the station of the Gaoyou Ms 4.9 and Rudong Ms 3.8 offshore earthquakes. The abnormal data analysis method was evaluatedin order to find precursor reference before the earthquake in the future.
