| Abstract: | The changes of some precursory observation in Shanxi area before Wenchuan Ms8.0 earthquake on May 12,2008 were analysed,and following conclutions are drawn.Firstly,the precursor waves of low frequent are main characters of the precursory change before the earthquake,and its superior period are 64-128 min.Secondly,the distribution of the abnormal points is in the same direction with the primary rupture of Wenchuan Ms8.0 earthquake.Thirdly,low-frequency precursory waves occured in a crowded time,mainly from 1... |
