摘要 惠灵顿断层是北岛南部主要的活动右旋走滑断层之一，对大惠灵顿地区具有重大的地震危险。 Long Gully/Karori 水库地区和 Kaitoke 附近断层上的沟槽挖掘，以及 Te Mania 的第四纪地层和土壤研究表明，沿惠灵顿断层南部最近发生的地表破裂事件为 300-450 cal B.P.。 （公元 1950 年之前的日历年），下一个最古老的事件是 670-830 cal B.P.这两次事件之间的时间间隔为 220-530 年。根据先前报告的在 Emerald Hill 计算的 6.0–7.6 mm/年长期（约 140 ka）平均水平滑移率，以及在 Te Marua 测量的 3.2–4.7 m 单事件偏移量（最近的五个事件），惠灵顿断层这部分的平均复发间隔为 420–780 年。在长沟沟遗址，两条河道横向位移 c。 50米....
Abstract The Wellington Fault is one of the major active right‐lateral strike‐slip faults of the southern North Island and represents a significant seismic hazard to the greater Wellington region. Trench excavations across the fault in the Long Gully/Karori Reservoir area and near Kaitoke, along with Quaternary stratigraphic and soil studies at Te Mania, indicate that the most recent surface rupture event along the southern portion of the Wellington Fault was 300–450 cal B .P. (calendar years before A.D. 1950) and the next oldest event was 670–830 cal B.P. The elapsed time between these two events is 220–530 years. Based on the previously reported 6.0–7.6 mm/yr, long‐term (c. 140 ka), average, horizontal slip rate calculated at Emerald Hill, and the 3.2–4.7 m single‐event offsets (the five most recent events) measured at Te Marua, the average recurrence interval for this portion of the Wellington Fault is 420–780 years. At the Long Gully trench site, two stream channels are laterally displaced by c. 50 m....
