英文摘要	Hypocentral loci are very useful for reliable and visual earthquake location, but they can hardly be analytically expressed when the velocity model is complex. There is a ray-tracing based numerical method to calculate them, in which a focal locus is represented in terms of ray paths from the minimum point ( namely initial point) to low residual points ( referred as hypocentral locus reference points, HLRPs) in its residual field. It has no restrictions on the complexity of the velocity model and can produce quite fine results. However, this method is incapable of addressing multi-segment loci and inadequate for processing large quantity of data. Additionally, it is rather laborious and difficult to set its controlling parameters for obtaining both fine and complete hypocentral loci. This paper presents an improvement of the ray-tracing based method.
