摘要

This paper introduces the auxiliary function method, a novel, fast and simple approach for waveform based earthquake location. From any initial hypocenter and origin time, we can construct the auxiliary function, whose zero set contains the real earthquake hypocenter and the origin time. This translates the earthquake location problem into the problem of searching the common zeros of the auxiliary functions.
