By analyzing shadow zone earthquakes in all direction recorded in Xi′an Seismic Station in recent year,the confirmation method for Lg1 ,Lg2 waves is elaborated.Using Matlab to analyze data,the traveltime relationship between S wave and Lg1 ,Lg2 wave is obtained,the analysis speed and accuracy for shadow zone seismic analysis speed and accuracy is improved. This result provides referencable experience for quick report of strong earthquake with the data of single station and rountine analysis.
