摘要

On 14 November 2001, an extraordinarily large earthquake (M_S 8.1) occurred on the Hoh Saihu segment of the eastern Kunlun fault, northern Tibetan Plateau. The seismogenic fault, Hoh Saihu segment, is a left-lateral fault with a high slip rate in the geological history,and the average slip rate reaches (14.8±2.8) mm/a since the Late Pleistocene. Different slip rates of Hoh Saihu segment can affect the fault motion in the future. So, this paper analyzes the effect of different slip rates and different initial friction coefficients on the fault surface of the Hoh Saihu segment of eastern Kunlun fault on the rupture behaviors of the fault.
