【摘要】 将高阶统计量方法运用到形变固体潮汐资料处理中,对2006年4月9日山东莘县与河南濮阳交界的濮阳ML4.6地震前泰安地震台的潮汐形变观测资料进行了处理与分析。发现在地震前的一段时间内有异常信号介入,分析结果中的低点对地震异常信息的提取有指导意义。此方法能较好的提取潮汐形变短临异常。更多还原

【Abstract】 The higher-order statistics method is applied to processing the earthquake tidal deformation observation data.The tidal deformation observation data of Tai′an seismic station before the ML4.6 earthquake in the boundary region of Puyang and Xinxian counties on April 9,2006,are processed and analyzed.In the period of time before the earthquake,intervention of abnormal signal is found.On low point of the results has guiding significance to seismic anomaly information extraction.This method can extract some short-impending anomalies of seismic tidal.更多还原
