Figure 1 - Northridge Aftershocks

Figure 1. a) Magnitude 2.5 and larger aftershocks from January 17, 1994 to December 31, 1994. The event locations were obtained from the SCEC data center. Fault plane solutions of the mainshock, AS2 (23:33UTC) and their respective empirical Green's functions were computed by moment tensor inversion of long-period waves. b) Cross-section BB'. The filled symbols are those aftershocks which are located within 3 km of the fault plane defined by the mainshock hypocenter and the south dipping nodal plane of the moment tensor inversion.
