... at the well-known Branch River and Saxton River sites along the Wairau (Alpine) and Awatere strike-slip faults, South Island, New Zealand, reveal that fault-related deformation patterns expressed in the topography at these sites are markedly less structurally complex along the higher-displacement (hundreds...

... anisotropic lower crust beneath the two northernmost faults of the fault system. These observations suggest that distributed deformation, not slip on a narrow vertical fault, accommodates displacement in the lower crust below the 120–480 km of right-lateral slip across the Wairau fault, one splay...

... restraining bend of the Alpine fault has the same average slip rate as the Wairau fault, 4-6 mm/yr. Even though the Alpine fault is an east-dipping, reverse-separation fault at the restraining bend, this low slip rate results in uplift of the Spenser Mountains east of the bend at a rate lower than...
