| Abstract: | In this paper, we briefly introduce the basic theory of S-wave splitting method, its calculating method in earthquake study and some preliminary application to the study on Rongchang earthquakes. The digital wave data of Rongchang station during the period from January 2003 to October 2005 are selected and processed. Using the S-wave splitting method, we obtain the predominant direction of the stress and the delay time of S-wave in different periods, which provides useful information for earthquake prediction and the study of the regional stress field. |
