摘要

Field investigations allow to constrain the co-seismic surface rupture zone of ~400km with a strike-slip up to 16.3 m associated with the 2001Mw 7.8 Central Kunlun earthquake that occurred along the western segment of the Kunlun fault,northern Tibet.The co-seismic rupture structures are almost duplicated on the pre-existing fault traces of the Kunlun fault.The deformational characteristics of the co-seismic surface ruptures reveal that the earthquake had a nearly pure strike-slip mechanism.Theg eologic and topographice vidence clearly shows that spatial distributions of the co-seismic surface ruptures are re-stricted by the pre-existing geological structures of the Kunlun fault.
