Abstract

Combining remote sensing imagery interpretation of active faults with Landsat ETM, Google Earth and ASTER GDEM image data, this paper analysed the spatial distribution and geometry and motion characteristics of the south section of Longmenshan tectonic belt. The results showed that Longmenshan tectonic belt occurred obvious fracture dispersion in the process of extending to the south. The tectonic zone gradually widened, developing 5 faults and many secondary faults. The southernmost of Longmenshan tectonic zone was stopped by Xianshuihe sinistral strike-slip fault. Activities of Luding fault, Tianquan fault, Lushan fault and Dayi-Mingshan fault are more obvious. The former two are south-extending branches of Beichuan-Yingxiu fault, the latter two are south-extending branches of Anxian-Guanxian fault. The tectonic deformation of south Longmenshan tectonic belt was dispersed to a plurality of secondary faults, resulting in surface activity signs of single fault weaken significantly. So the potential earthquake frequency and intensity of single fault will also be correspondingly smaller, but potential seismic source region will be more dispersed. According to the existing seismic geological data, we should pay attention to the crustal stability and strong earthquake risk in Ya'an and Luding areas in the future.
