Slip rate of active faults is deterministic to compare active earthquake behaviors among different faults or different segments along a fault, and also it is a key parameter for seismic hazard assessment. Based on several three-dimension trench excavations, reliable radiocarbon dating at the bottom of stratigraphic unit in the triangular pull-apart basin, detailed field investigation along the Daqingliangzi section of Zemuhe fault and accurate RTK (GPS) survey, the authors suggest that Holocene average left-lateral slip rate of the Zemuhe fault is constrained between 2.4±0.2 mm/a and 3.6 mm/a. However this strike-slip rate is much more accordant with paleoseismic recurrence behaviors and present velocity field obtained from GPS measurement across the Zemuhe fault.
