| 英文摘要 | The 14 November 2001 Kunlun, China, earthquake with a moment magnitude (M-w) 7.8 occurred along the Kusai Lake-Kunlun Pass fault of the Kunlun fault system. We document the spatial distribution and geometry of surface rupture zone produced by this earthquake, based on high-resolution satellite (Landsat ETM, ASTER, SPOT and IKONOS) images combined with field measurements. Our results show that the surface rupture zone can be divided into five segments according to the geometry of surface rupture, including the Sun Lake, Buka Daban-Hongshui River, Kusai Lake, Hubei Peak and Kunlun Pass segments from west to east. These segments, each 55 to 130 km long, are separated by step-overs. The Sun Lake segment extends about 65 km with a strike of N45 degrees similar to 75 degrees W (between 90 degrees 05'E similar to 90 degrees 50'E) along the previously unrecognized West Sun Lake fault. A gap of about 30 km long exists between the Sun Lake and Buka Daban Peak where no obvious surface ruptures can be observed either from the satellite images or field observations. The Buka Daban-Hongshui River, Kusai Lake, Hubei Peak and Kunlun Pass segments run about 365 km striking N75 degrees similar to 85 degrees W along the southern slope of the Kunlun Mountains (between 91 degrees 07'E similar to 94 degrees 58'E). This segmentation of the surface rupture is well correlated with the pattern of slip distribution measured in the field. Detailed mapping suggest that these five first-order segments can be further separated into over 20 second-order segments with a length of 10-30 km, linked by smaller scale step-overs or bends. |
