Ground Surface Rupture Complexity on the Northern Alpine Fault, Aotearoa New Zealand
Lidar data and field observations are used to investigate the factors influencing rupture morphology complexity along the Northern Alpine Fault in Aotearoa New Zealand. Structural and geomorphic mapping covering approximately 220 kilometres of the fault reveals enhanced rupture complexity at fault junctions and distinct variations in rupture complexity with geological and topographic variations. Measurement of fault zone widths at 50-meter intervals and fault corrugation analysis is used to quantify along-strike complexity. Rupture mapping results are used to speculate on rupture processes and extents in past and future Alpine Fault earthquakes.
