航卫片解译及野外实地调查结果表明，在错那、哲古错、穷结之间展布有一条北北西向的全新世活动断裂。在北北东向的主压应力场作用下，错那一哲古错断裂表现为右旋剪切运动性质。通过对历史地震资料较详细的研究和祖略的野外地震地质调查，笔者认为，1806年西藏错那7(1/2)级地震应为错那一哲古错断裂的右旋错动所致。
Hangwei film interpretation and field survey results show that, at the wrong, Zhege fault, poor knot between the distribution of a north-west movement of the Holocene. Under the action of the north-north-east principal compressive stress field, the fault of that Zhege ancient fault shows the nature of right-lateral shearing motion. Through the detailed study of historical seismic data and the field seismic geological survey of Zulu, the author thinks that the 7 (1/2) earthquakes in the fault of Tibet in 1806 should be caused by the dextral deviation of the Zhehe fault .
