中文摘要：

采用欧空局ERS—1卫星雷达数据获取了1993年Mw 6.2级西藏拉孜地震同震形变场,并采用弹性位错模型反演了该地震的断层参数。结果显示该地震产生的最大地表位移约为12 cm,断层倾角为42°,不支持该断层为低角度正断层的论断。

英文摘要：

We calculated coseismic deformation associated with the 1993 Mw 6. 2 Lhatse earthquake using radar images acquired by the ERS-1 satellite. Based on the coseismic interferograms,we constrained the fault parameters using an elastic dislocation model. The result shows maximum surface displacement of 12 cm,dip angle of 42 degrees,which does not support the low-angle normal fault of the Pamqu-Xianza Rift.
