【摘要】 2006年11月23日新疆精河Ms5.1级地震前,精河台的伸缩、倾斜和长水管资料均出现了明显的前兆异常变化。利用形态分析、一阶差分、矢量合成、卡尔曼滤波方法对资料进行分析处理,结果表明新疆乌苏、精河间Ms5.1级地震前的短临异常较为明显,年变幅观测曲线畸变、日均值曲线转折甚至打破年变、矢量转向、速率变化超两倍均方差等,显示出这次地震之前地形变异常具有较高的可信度。更多还原

【Abstract】 On November 23,2006,before Jinghe Ms5.1 earthquake,the extensometer,tilt and the long water pipe inclinometer in Jinghe seismic station presented obvious anomalies which are analyzed by the morphologic method,differential method,Kallman’s filtering method.The results show that the unusual variation,daily mean values and the ratio are extreamly anomaly before the Ms5.1 earthquake,and this also shows that these deformation anomalies are reliable before earthquakes.更多还原
