| Abstract: | The theory to distinguish P wave and S wave in local events through Wadachi method was discussed in this paper.We got the basic formula and calculating method which could be used to express correlative coefficient r of s-p and p onset.We discussed the application of Wadachi method in seismic net to locate local events.We developed the software to improve precision of local earthquake locating through Wadachi method and showed how to use this software by some examples. |
