Abstract
The Porter’s Pass-Amberley Fault Zone (PPAFZ) is a complex zone of anastomosing faults and folds bounding the southeastern edge of the transition from subducting Pacific Plate to continental collision on the Australia Plate boundary. This study combines mapping of a 2000 km2 zone from the Southern Alps northeast to the coast near Amberley, 40 km north of metropolitan Christchurch, with an analysis of seismicity and a revision of regional seismic hazard.
