Wrench tectonics flip at oblique subduction. A model from New Zealand Saut de tectonique décrochante en subduction oblique. Un modèle néo-zélandais
2003
In eastern North Island New Zealand, oblique subduction of the Pacific Plate beneath the Australian Plate is associated with strain partitioning. Dextral along-strike component of displacement occurred first at Early Miocene major faults within the eastern fore-arc domain. These faults were active from Early Miocene to Pliocene times. Since Pliocene times most of the movement occurs at western faults such as the Wellington Fault. The latter joins the back-arc domain to the north. The jump of wrench faulting is related with the oblique opening of the back- arc domain. Both phenomena are impeded southwards by the Hikurangi oceanic plateau entering
