| 摘 要： | Introduction When the distribution of a cluster of earthquakes is concentrated, distance between hypocen-ters is much smaller than the event-station distance and than the scale length of the velocity het-erogeneity in the hypocenter region; in this case, the ray path from each hypocenter to a common station will be almost the same. The relative location method can be applied to accurate location of the cluster in the above case. In this approach, the relative location is calculated with the ar…

| Abstract: | The theory and method of relative location technique were described in the paper. The travel-time difference equa-tions for five phases (Pg, Sg, P11, S11 and Ph) were given. By using the multiplet relative location approach andwave correlation correction, the aftershock cluster of the Shunyi earthquake occurred on December 16, 1996 wasrelocated. The depth calculation was constrained by using multiple seismic phases. The relocation results werecompared with that from traditional absolute location techniques. |
