Refraction, scattering and multipath are often severe in regional seismic array data. An example from the NORESS array in southeastern Norway shows the extent of the problem and illustrates the ambiguities in event location that can result from FK analysis. The location estimation problem might be recast as a multiple hypothesis test on location in regions which are characterized by a moderate number of discrete repeating sources. Unlocated events are correlated against calibrating "master" events for these source locations. The best match identifies the origins of the unlocated events. An example establishes the plausibility of the method.
