- Crustal Deformation and Earthquake Fault of the 2005 Northern Pakistan Earthquake Detected by Spaceborne Synthetic Aperture Rader
抄録
We mapped the crustal deformation of the Northern Pakistan earthquake of 8 October 2005 occurred in the Kashmir region spatially with Synthetic Aperture Radar (SAR) data from a satellite, and found that the area with more than 1-m of observed deformation occupies a ~90-km long northwest-southwest trending strip-shaped area. The area north of Muzaffarabad, a heavily-damaged area, has the maximum deformation more than 6-m. There are known active faults stretching to the northwest and southeast near the epicenter, which reveal some uplift (on the northeast side) and dextral strike-slip activities. We found that the detected crustal deformation was along these active faults and all observations were consistent in the sense of fault offsets. There are two important findings. First, the earthquake occurred on pre-existing active faults. This means surveying existing active faults is important for estimating future earthquake hazards and risk. Second, the satellite data show the ruptured earthquake faults in detail, allowing relief planners to quickly simulate and estimate the seismically damaged areas and the extent of the damage for prompt rescue and relief operations.
