AbstractThe Adaptive Quantum Genetic Algorithm (AQGA) is introduced into the seismic relocation, and shows up its effectiveness, the strong global searching ability, and the anti-noise ability demonstrated by a variety of numerical tests. Even though the seismic stations are limited and are not distributed ideally, the obtained results are still satisfactory by averaging multiple inversion results. In addition, the AQGA has a higher accuracy in relocation and the error of relocation for the algorithm is estimated to be small by using several numerical tests. Then the algorithm is applied to the relocation of the earthquakes occurred in Shandong Province and neighboring areas. The root mean square residual decreases from 1.162s to 0.621s after relocation, and the focal depths of most earthquakes are less than 20 km, indicating that the earthquakes mostly occurred in the upper and middle crust. The distribution of the hypocenters along the profiles indicates that most earthquakes are controlled by the deep strike-slip faults in the study area, and the moderate and large earthquakes mainly took place around the high/low velocity anomalies, especially in the transitional zone between the high- and the low-velocity anomalies.
