| Abstract: | The genetic algorithm is applied to seismic location, and its results are compared with those of Powell algorithm and traditional algorithm. It is shown that when genetic algorithm is used, the precision of determined origin time is higher and the determined depth is more reliable. This method is better when the stations concentrate on one side of an earthquake. |
