| Abstract: | The characteristics of precursor variation before the M5.1 earthquake on July 4,2006,in Wenan of Hebei province is summarized.It is considered that the large number,completeness and acceleration of precursors are the characteristics of a coming strong earthquake.The geothermal variations at Sanmafang and Changping stations have the significance indicating the occuring time of Wenan earthquake.Through summarizing the precursor variations of Wenan earthquake,the necessities of synthetical prediction,precursor verification,precursor following and the further study are understanded. |
