Wherever a large earthquake occurs, the National Earthquake Information Center (NEIC), part of the U.S. Geological Survey (USGS), reports its hypocenter location within a few hours of the event. Since digital waveform data are available at many stations worldwide, it is in most cases easy to obtain a centroid moment tensor (CMT) solution and infer the preliminary rupture mechanism of a large earthquake soon after its occurrence, wherever it occurs (e.g., Dziewonski et al., 1994; Kawakatsu et al., 1994; Sipkin, 1994; Kikuchi et al., 1999). It is difficult, however, to determine...
