| Abstract: | The application of DIMAS software for earthquake location is introduced and the principle to determine the azimuth is expounded. The effect of earthquake location, include near earthquake, teleseimics and very far earthquakes is demonstrated. The reasons for location error are analyzed in detailed and the methods for improving the location precision are proposed. |
