Active tectonics west of New Zealand ́s Alpine Fault: South Westland Fault Zone activity shows Australian Plate instability.

Abstract

The 300 km long South Westland Fault Zone (SWFZ) is within the footwall of the Central Alpine Fault (<20 km away) and has 3500m of dip-slip displacement, but it has been unknown if the fault is active. Here the first evidence for SWFZ thrust faulting in t
