摘要
应用Mann-Kendall法对1998年泾阳4.8级地震和2009年高陵4.4级地震某些指标数据序列进行异常分析。分析结果表明地震前兆观测数据的某些指标呈现出异常变化,应用此方法可以确定出突变的具体时间。本研究对地震预报预测有积极作用。
Using the Mann-Kendall method, an abnormal analysis of some index data sequences collected from Jingyang Ms4.8 earthquake in 1998 and Gaoling Ms4.4 earthquake in 2009 is done. Analyse results show that some indexes of the precursory observation data of earthquake appeared abnormal change. Applying this method, the time of change-point can be identified. The works have impacted on earthquake forecast.
