| Abstract: | The author has studied the spatial characteristics of the LURR (Loading/Unloading Re spouse Ratio )in seismogenic zone before and after the Gonghe earthquake (Ms 7. 0 ), Y value(LURR ) anomaly before the earthquake is abvious .and it is useful to predict short -termstrong post - earthquake that Y value anomalism after major shock. |
