长期滑动速率是从昆仑断层沿着大部分长度的累积偏移量的一致10 Be、26 Al和14 C测年得出的。6个部位的数值表明自140 kyr BP以来的均匀滑动（11.5±2.0 mm/年）。这种相对较高的滑动速率对应于亚洲地壳速度场的一阶不连续性。在该断裂的两段上，分别每隔1850年和1420年发生一次8级和7.5级地震，其特征滑动量分别为1.10 ±2 m和4.4± 0.4m。
A long‐term slip‐rate is derived from concordant 10Be, 26Al and 14C dating of cumulative offsets along much of the length of the Kunlun Fault. Values at 6 sites indicate uniform slip (11.5±2.0 mm/yr) since ∼40 kyr BP. This relatively high slip rate corresponds to a first‐order discontinuity in the Asian crustal velocity field. M∼8 and M∼7.5 earthquakes on 2 segments of the fault recur with characteristic slip (∼10±2 m and 4.4±0.4 m) every ∼850 and ∼420 yrs, respectively.
