摘要：An inland crustal earthquake with a magnitude of 6.5 that occurred in the southeast of Iran on December 20, 2010 ruptured an unknown fault at depth. Applying interferometric SAR (InSAR) analysis using ALOS/PALSAR data to the earthquake, we detected the coseismic signal from both ascending orbit interferogram of fine beam mode and descending orbit interferogram of ScanSAR mode. Our preferred fault model, assuming a rectangular fault with a uniform slip, shows a nearly pure dextral fault motion with NE-SW-oriented strike. The estimated moment magnitude is 6.6. The fault of the mainshock is on the southern extension of the Kahurak fault, suggesting that the causative fault of this event is probably the identical fault system to the Kahurak fault.
