- Summary
- The Waverley FaultZone, c. 40 km northwest of Wanganui, New Zealand, has clearly defined surface fault scarps trending southwest-northeast for a distance of c. 8 km, from Lake Oturi in the south through to the Brunswick Terrace strandline northeast of Waverley. Paleoseismic studies involving trenching were carried out to determine the timing of past earthquakes, the amount of surface displacement associated with them, and an estimation of associated earthquake magnitudes. The Waverley Fault Zone has been the site of several large, surface-rupturing events in the past. Trench excavations across the fault zone revealed that the zone consists of normal faults dipping 50-80
