陆地卫星影象表明西藏地区存在一系列活动断裂带,晚第三纪以来的新生盆地和火山活动都十分强烈。从卫星照片中的线性构造及其组合特征分析,西藏高原具有三种不同的构造组合,雅鲁藏布江以南多为近东西向线性构造,为强烈挤压的形变特征,中部多为连续分布的透镜状构造,反映了地壳物质塑性流动的形变特征,羌塘高原则为共轭破裂的形变特征。这些特征客观地反映了西藏高原各块体之间的力学性质和介质条件的差异,也控制了西藏地区的地震活动性。
Terrestrial satellite images show that there are a series of active fault zones in Tibet, and the Neocene basins and volcanic activities since the Late Tertiary are very strong. From the satellite images of the linear structure and characteristics of the combination of analysis, the Tibet Plateau has three different tectonic combinations, mostly south of the Yarlung Zangbo River near the east-west linear structure, a strong extrusion deformation characteristics, the central mostly continuous distribution of lenticular Structure, which reflects the deformation characteristics of crustal material plastic flow. The Qiangtang Plateau is the deformation feature of conjugate rupture. These characteristics objectively reflect the differences in mechanical properties and medium conditions between the blocks on the Tibetan Plateau and also control the seismicity in Tibet.
