| Abstract: | 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. |
