Utilizing Results from InSAR to Develop Seismic Location Benchmarks and Implications for Seismic Source Studies
Search for Secondary Rupture Event
As the first step in determining the candidate events for the secondary rupture, we determined which of the events from the EDR catalog were within the time period for the InSAR satellite pass and after the mainshock (08 NOV1997 - 02 DEC 1997) (Peltzer et al., 1999). 42 were possible candidates for the secondary rupture (Figure 1).
Also used several different iterations of the JHD approach to attempt to identify secondary rupture event. Results were inconclusive.
