Figure 1. Map view ( top) and cross-section ( bottom) of the aftershock distribution for the Northridge earthquake from January 17 to November 31, 1994. Aftershock locations shown are the 3-D relocations of Mori \ETAL, 1995. Thick lines indicate the dimensions of the surface projection of the fault plane used in this study. Contours (interval 0.4 m) show the slip pattern determined from the combined inversion of waveform and geodetic data.
