Abstract: A local earthquake locating method based on genetic algorithm is introduced in this paper. In this method, the floating-point gene expression and same value space for both gene and earthquake parameters are used to avoid coding and decoding. A dynamic termination condition and unique resolution are also suggested in this paper. It is verified by practical computation that this method is stable and does not depend on initial value, as the same, it reaches a high time efficiency. It is a practicable algorithm for daily local earthquake locating.

Key words: Earthquake locating, Genetic algorithm, Floating point gene expression, Stability, Time efficiency
