Coda waves arise from scattering to form the later arriving components of a seismogram. Coda wave interferometry is an emerging tool for constraining earthquake source properties from the intereference pattern of coda waves between nearby events. A new earthquake location algorithm is derived which relies on coda wave based probabilistic estimates of earthquake separation. The algorithm can be used with coda waves alone or in tandem with travel time data. Synthetic examples in 2D and 3D and real earthquakes on the Calaveras Fault, California are used to demonstrate the potential of coda waves for locating poorly recorded earthquakes. It is demonstrated that coda wave interferometry: (a) outperforms traditional earthquake location techniques when the number of stations is small; (b) is self-consistent across a broad range of station situations; and (c) can be used with a single station to locate earthquakes.
